Summary

Public constructors

AutoCloseInputStream(ParcelFileDescriptor pfd)

Public methods

void close()

Closes this file input stream and releases any system resources associated with the stream.

int read()

Reads a byte of data from this input stream.

int read(byte[] b, int off, int len)

Reads up to len bytes of data from this input stream into an array of bytes.

int read(byte[] b)

Reads up to b.length bytes of data from this input stream into an array of bytes.

Inherited methods

int available()

Returns an estimate of the number of remaining bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream.

void close()

Closes this file input stream and releases any system resources associated with the stream.

void finalize()

Ensures that the close method of this file input stream is called when there are no more references to it.

FileChannel getChannel()

Returns the unique FileChannel object associated with this file input stream.

final FileDescriptor getFD()

Returns the FileDescriptor object that represents the connection to the actual file in the file system being used by this FileInputStream.

int read()

Reads a byte of data from this input stream.

int read(byte[] b, int off, int len)

Reads up to len bytes of data from this input stream into an array of bytes.

int read(byte[] b)

Reads up to b.length bytes of data from this input stream into an array of bytes.

long skip(long n)

Skips over and discards n bytes of data from the input stream.

int available()

Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected.

void close()

Closes this input stream and releases any system resources associated with the stream.

void mark(int readlimit)

Marks the current position in this input stream.

boolean markSupported()

Tests if this input stream supports the mark and reset methods.

static InputStream nullInputStream()

Returns a new InputStream that reads no bytes.

int read(byte[] b)

Reads some number of bytes from the input stream and stores them into the buffer array b.

abstract int read()

Reads the next byte of data from the input stream.

int read(byte[] b, int off, int len)

Reads up to len bytes of data from the input stream into an array of bytes.

byte[] readAllBytes()

Reads all remaining bytes from the input stream.

int readNBytes(byte[] b, int off, int len)

Reads the requested number of bytes from the input stream into the given byte array.

byte[] readNBytes(int len)

Reads up to a specified number of bytes from the input stream.

void reset()

Repositions this stream to the position at the time the mark method was last called on this input stream.

long skip(long n)

Skips over and discards n bytes of data from this input stream.

void skipNBytes(long n)

Skips over and discards exactly n bytes of data from this input stream.

long transferTo(OutputStream out)

Reads all bytes from this input stream and writes the bytes to the given output stream in the order that they are read.

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

abstract void close()

Closes this stream and releases any system resources associated with it.

abstract void close()

Closes this resource, relinquishing any underlying resources.

Public constructors

AutoCloseInputStream

Added in API level 1
public AutoCloseInputStream (ParcelFileDescriptor pfd)

Parameters
pfd ParcelFileDescriptor

Public methods

close

Added in API level 1
public void close ()

Closes this file input stream and releases any system resources associated with the stream.

If this stream has an associated channel then the channel is closed as well.

Throws
IOException

read

Added in API level 1
public int read ()

Reads a byte of data from this input stream. This method blocks if no input is yet available.

Returns
int the next byte of data, or -1 if the end of the file is reached.

Throws
IOException

read

Added in API level 1
public int read (byte[] b, 
                int off, 
                int len)

Reads up to len bytes of data from this input stream into an array of bytes. If len is not zero, the method blocks until some input is available; otherwise, no bytes are read and 0 is returned.

Parameters
b byte: the buffer into which the data is read.

off int: the start offset in the destination array b

len int: the maximum number of bytes read.

Returns
int the total number of bytes read into the buffer, or -1 if there is no more data because the end of the file has been reached.

Throws
IOException

read

Added in API level 1
public int read (byte[] b)

Reads up to b.length bytes of data from this input stream into an array of bytes. This method blocks until some input is available.

Parameters
b byte: the buffer into which the data is read.

Returns
int the total number of bytes read into the buffer, or -1 if there is no more data because the end of the file has been reached.

Throws
IOException
