ShortBuffer

abstract class ShortBuffer : Buffer, Comparable<ShortBuffer!>

allocate

open static fun allocate(capacity: Int): ShortBuffer!

Allocates a new short buffer.

The new buffer's position will be zero, its limit will be its capacity, its mark will be undefined, each of its elements will be initialized to zero, and its byte order will be the native order of the underlying hardware. It will have a backing array, and its array offset will be zero.

Parameters
capacity	Int: The new buffer's capacity, in shorts

Return
ShortBuffer!	The new short buffer

Exceptions
java.lang.IllegalArgumentException	If the capacity is a negative integer

array

fun array(): ShortArray!

Returns the short array that backs this buffer  (optional operation).

Modifications to this buffer's content will cause the returned array's content to be modified, and vice versa.

Invoke the hasArray method before invoking this method in order to ensure that this buffer has an accessible backing array.

Return
ShortArray!	The array that backs this buffer

Exceptions
java.nio.ReadOnlyBufferException	If this buffer is backed by an array but is read-only
java.lang.UnsupportedOperationException	If this buffer is not backed by an accessible array

arrayOffset

fun arrayOffset(): Int

Returns the offset within this buffer's backing array of the first element of the buffer  (optional operation).

If this buffer is backed by an array then buffer position p corresponds to array index p + arrayOffset().

Invoke the hasArray method before invoking this method in order to ensure that this buffer has an accessible backing array.

Return
Int	The offset within this buffer's array of the first element of the buffer

Exceptions
java.nio.ReadOnlyBufferException	If this buffer is backed by an array but is read-only
java.lang.UnsupportedOperationException	If this buffer is not backed by an accessible array

asReadOnlyBuffer

abstract fun asReadOnlyBuffer(): ShortBuffer!

Creates a new, read-only short buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer; the new buffer itself, however, will be read-only and will not allow the shared content to be modified. The two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, mark values, and byte order will be identical to those of this buffer.

If this buffer is itself read-only then this method behaves in exactly the same way as the duplicate method.

Return
ShortBuffer!	The new, read-only short buffer

clear

open fun clear(): Buffer!

Clears this buffer. The position is set to zero, the limit is set to the capacity, and the mark is discarded.

Invoke this method before using a sequence of channel-read or put operations to fill this buffer. For example:

buf.clear();     // Prepare buffer for reading
  in.read(buf);    // Read data

This method does not actually erase the data in the buffer, but it is named as if it did because it will most often be used in situations in which that might as well be the case.

Return
Buffer!	This buffer

compact

abstract fun compact(): ShortBuffer!

Compacts this buffer  (optional operation).

The shorts between the buffer's current position and its limit, if any, are copied to the beginning of the buffer. That is, the short at index p = position() is copied to index zero, the short at index p + 1 is copied to index one, and so forth until the short at index limit() - 1 is copied to index n = limit() - 1 - p. The buffer's position is then set to n+1 and its limit is set to its capacity. The mark, if defined, is discarded.

The buffer's position is set to the number of shorts copied, rather than to zero, so that an invocation of this method can be followed immediately by an invocation of another relative put method.

Return
ShortBuffer!	This buffer

Exceptions
java.nio.ReadOnlyBufferException	If this buffer is read-only

compareTo

open fun compareTo(other: ShortBuffer!): Int

Compares this buffer to another.

Two short buffers are compared by comparing their sequences of remaining elements lexicographically, without regard to the starting position of each sequence within its corresponding buffer. Pairs of short elements are compared as if by invoking Short#compare(short,short).

A short buffer is not comparable to any other type of object.

Parameters
o	the object to be compared.

Return
Int	A negative integer, zero, or a positive integer as this buffer is less than, equal to, or greater than the given buffer

Exceptions
java.lang.NullPointerException	if the specified object is null
java.lang.ClassCastException	if the specified object's type prevents it from being compared to this object.

duplicate

abstract fun duplicate(): ShortBuffer!

Creates a new short buffer that shares this buffer's content.

The content of the new buffer will be that of this buffer. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.

The new buffer's capacity, limit, position, mark values, and byte order will be identical to those of this buffer. The new buffer will be direct if, and only if, this buffer is direct, and it will be read-only if, and only if, this buffer is read-only.

Return
ShortBuffer!	The new short buffer

equals

open fun equals(other: Any?): Boolean

Tells whether or not this buffer is equal to another object.

Two short buffers are equal if, and only if,

1. They have the same element type,
2. They have the same number of remaining elements, and
3. The two sequences of remaining elements, considered independently of their starting positions, are pointwise equal.

A short buffer is not equal to any other type of object.

Parameters
obj	the reference object with which to compare.
ob	The object to which this buffer is to be compared

Return
Boolean	true if, and only if, this buffer is equal to the given object

flip

open fun flip(): Buffer!

Flips this buffer. The limit is set to the current position and then the position is set to zero. If the mark is defined then it is discarded.

After a sequence of channel-read or put operations, invoke this method to prepare for a sequence of channel-write or relative get operations. For example:

buf.put(magic);    // Prepend header
  in.read(buf);      // Read data into rest of buffer
  buf.flip();        // Flip buffer
  out.write(buf);    // Write header + data to channel

This method is often used in conjunction with the compact method when transferring data from one place to another.

Return
Buffer!	This buffer

get

abstract fun get(): Short

Relative get method. Reads the short at this buffer's current position, and then increments the position.

Return
Short	The short at the buffer's current position

Exceptions
java.nio.BufferUnderflowException	If the buffer's current position is not smaller than its limit

get

abstract fun get(index: Int): Short

Absolute get method. Reads the short at the given index.

Parameters
index	Int: The index from which the short will be read

Return
Short	The short at the given index

Exceptions
java.lang.IndexOutOfBoundsException	If index is negative or not smaller than the buffer's limit

get

open fun get(
    dst: ShortArray!, 
    offset: Int, 
    length: Int
): ShortBuffer!

Relative bulk get method.

This method transfers shorts from this buffer into the given destination array. If there are fewer shorts remaining in the buffer than are required to satisfy the request, that is, if length > remaining(), then no shorts are transferred and a BufferUnderflowException is thrown.

Otherwise, this method copies length shorts from this buffer into the given array, starting at the current position of this buffer and at the given offset in the array. The position of this buffer is then incremented by length.

In other words, an invocation of this method of the form src.get(dst, off, len) has exactly the same effect as the loop

<code>for (int i = off; i &lt; off + len; i++)
          dst[i] = src.get();
  </code>

except that it first checks that there are sufficient shorts in this buffer and it is potentially much more efficient.

Parameters
dst	ShortArray!: The array into which shorts are to be written
offset	Int: The offset within the array of the first short to be written; must be non-negative and no larger than dst.length
length	Int: The maximum number of shorts to be written to the given array; must be non-negative and no larger than dst.length - offset

Return
ShortBuffer!	This buffer

Exceptions
java.nio.BufferUnderflowException	If there are fewer than length shorts remaining in this buffer
java.lang.IndexOutOfBoundsException	If the preconditions on the offset and length parameters do not hold

get

open fun get(dst: ShortArray!): ShortBuffer!

Relative bulk get method.

This method transfers shorts from this buffer into the given destination array. An invocation of this method of the form src.get(a) behaves in exactly the same way as the invocation

src.get(a, 0, a.length) 

Parameters
dst	ShortArray!: The destination array

Return
ShortBuffer!	This buffer

Exceptions
java.nio.BufferUnderflowException	If there are fewer than length shorts remaining in this buffer

get

open fun get(
    index: Int, 
    dst: ShortArray!, 
    offset: Int, 
    length: Int
): ShortBuffer!

Absolute bulk get method.

This method transfers length shorts from this buffer into the given array, starting at the given index in this buffer and at the given offset in the array. The position of this buffer is unchanged.

An invocation of this method of the form src.get(index, dst, offset, length) has exactly the same effect as the following loop except that it first checks the consistency of the supplied parameters and it is potentially much more efficient:

<code>for (int i = offset, j = index; i &lt; offset + length; i++, j++)
          dst[i] = src.get(j);
  </code>

Parameters
index	Int: The index in this buffer from which the first short will be read; must be non-negative and less than limit()
dst	ShortArray!: The destination array
offset	Int: The offset within the array of the first short to be written; must be non-negative and less than dst.length
length	Int: The number of shorts to be written to the given array; must be non-negative and no larger than the smaller of limit() - index and dst.length - offset

Return
ShortBuffer!	This buffer

Exceptions
java.lang.IndexOutOfBoundsException	If the preconditions on the index, offset, and length parameters do not hold

get

open fun get(
    index: Int, 
    dst: ShortArray!
): ShortBuffer!

Absolute bulk get method.

This method transfers shorts from this buffer into the given destination array. The position of this buffer is unchanged. An invocation of this method of the form src.get(index, dst) behaves in exactly the same way as the invocation:

src.get(index, dst, 0, dst.length) 

Parameters
index	Int: The index in this buffer from which the first short will be read; must be non-negative and less than limit()
dst	ShortArray!: The destination array

Return
ShortBuffer!	This buffer

Exceptions
java.lang.IndexOutOfBoundsException	If index is negative, not smaller than limit(), or limit() - index < dst.length

hasArray

fun hasArray(): Boolean

Tells whether or not this buffer is backed by an accessible short array.

If this method returns true then the array and arrayOffset methods may safely be invoked.

Return
Boolean	true if, and only if, this buffer is backed by an array and is not read-only

hashCode

open fun hashCode(): Int

Returns the current hash code of this buffer.

The hash code of a short buffer depends only upon its remaining elements; that is, upon the elements from position() up to, and including, the element at limit() - 1.

Because buffer hash codes are content-dependent, it is inadvisable to use buffers as keys in hash maps or similar data structures unless it is known that their contents will not change.

Return
Int	The current hash code of this buffer

isDirect

abstract fun isDirect(): Boolean

Tells whether or not this short buffer is direct.

Return
Boolean	true if, and only if, this buffer is direct

limit

open fun limit(newLimit: Int): Buffer!

Sets this buffer's limit. If the position is larger than the new limit then it is set to the new limit. If the mark is defined and larger than the new limit then it is discarded.

Parameters
newLimit	Int: The new limit value; must be non-negative and no larger than this buffer's capacity

Return
Buffer!	This buffer

Exceptions
java.lang.IllegalArgumentException	If the preconditions on newLimit do not hold

mark

open fun mark(): Buffer!

Sets this buffer's mark at its position.

Return
Buffer!	This buffer

mismatch

open fun mismatch(that: ShortBuffer!): Int

Finds and returns the relative index of the first mismatch between this buffer and a given buffer. The index is relative to the position of each buffer and will be in the range of 0 (inclusive) up to the smaller of the remaining elements in each buffer (exclusive).

If the two buffers share a common prefix then the returned index is the length of the common prefix and it follows that there is a mismatch between the two buffers at that index within the respective buffers. If one buffer is a proper prefix of the other then the returned index is the smaller of the remaining elements in each buffer, and it follows that the index is only valid for the buffer with the larger number of remaining elements. Otherwise, there is no mismatch.

Parameters
that	ShortBuffer!: The byte buffer to be tested for a mismatch with this buffer

Return
Int	The relative index of the first mismatch between this and the given buffer, otherwise -1 if no mismatch.

order

abstract fun order(): ByteOrder!

Retrieves this buffer's byte order.

The byte order of a short buffer created by allocation or by wrapping an existing short array is the native order of the underlying hardware. The byte order of a short buffer created as a view of a byte buffer is that of the byte buffer at the moment that the view is created.

Return
ByteOrder!	This buffer's byte order

position

open fun position(newPosition: Int): Buffer!

Sets this buffer's position. If the mark is defined and larger than the new position then it is discarded.

Parameters
newPosition	Int: The new position value; must be non-negative and no larger than the current limit

Return
Buffer!	This buffer

Exceptions
java.lang.IllegalArgumentException	If the preconditions on newPosition do not hold

put

abstract fun put(s: Short): ShortBuffer!

Relative put method  (optional operation).

Writes the given short into this buffer at the current position, and then increments the position.

Parameters
s	Short: The short to be written

Return
ShortBuffer!	This buffer

Exceptions
java.nio.BufferOverflowException	If this buffer's current position is not smaller than its limit
java.nio.ReadOnlyBufferException	If this buffer is read-only

put

abstract fun put(
    index: Int, 
    s: Short
): ShortBuffer!

Absolute put method  (optional operation).

Writes the given short into this buffer at the given index.

Parameters
index	Int: The index at which the short will be written
s	Short: The short value to be written

Return
ShortBuffer!	This buffer

Exceptions
java.lang.IndexOutOfBoundsException	If index is negative or not smaller than the buffer's limit
java.nio.ReadOnlyBufferException	If this buffer is read-only

put

open fun put(src: ShortBuffer!): ShortBuffer!

Relative bulk put method  (optional operation).

This method transfers the shorts remaining in the given source buffer into this buffer. If there are more shorts remaining in the source buffer than in this buffer, that is, if src.remaining() > remaining(), then no shorts are transferred and a BufferOverflowException is thrown.

Otherwise, this method copies n = src.remaining() shorts from the given buffer into this buffer, starting at each buffer's current position. The positions of both buffers are then incremented by n.

In other words, an invocation of this method of the form dst.put(src) has exactly the same effect as the loop

while (src.hasRemaining())
          dst.put(src.get()); 

except that it first checks that there is sufficient space in this buffer and it is potentially much more efficient. If this buffer and the source buffer share the same backing array or memory, then the result will be as if the source elements were first copied to an intermediate location before being written into this buffer.

Parameters
src	ShortBuffer!: The source buffer from which shorts are to be read; must not be this buffer

Return
ShortBuffer!	This buffer

Exceptions
java.nio.BufferOverflowException	If there is insufficient space in this buffer for the remaining shorts in the source buffer
java.lang.IllegalArgumentException	If the source buffer is this buffer
java.nio.ReadOnlyBufferException	If this buffer is read-only

    src: ShortBuffer!, 
    offset: Int, 
    length: Int
): ShortBuffer!

Absolute bulk put method  (optional operation).

This method transfers length shorts into this buffer from the given source buffer, starting at the given offset in the source buffer and the given index in this buffer. The positions of both buffers are unchanged.

In other words, an invocation of this method of the form dst.put(index, src, offset, length) has exactly the same effect as the loop

<code>for (int i = offset, j = index; i &lt; offset + length; i++, j++)
      dst.put(j, src.get(i));
  </code>

except that it first checks the consistency of the supplied parameters and it is potentially much more efficient. If this buffer and the source buffer share the same backing array or memory, then the result will be as if the source elements were first copied to an intermediate location before being written into this buffer.

abstract fun slice(): ShortBuffer!

Creates a new short buffer whose content is a shared subsequence of this buffer's content.

The content of the new buffer will start at this buffer's current position. Changes to this buffer's content will be visible in the new buffer, and vice versa; the two buffers' position, limit, and mark values will be independent.
