FormattedNumberRange


public class FormattedNumberRange
extends Object implements FormattedValue

java.lang.Object
   ↳ android.icu.number.FormattedNumberRange


The result of a number range formatting operation. This class allows the result to be exported in several data types, including a String, an AttributedCharacterIterator, and a BigDecimal. Instances of this class are immutable and thread-safe.

Inherited methods

Public methods

appendTo

Added in API level 31
public A appendTo (A appendable)

Appends the formatted string to an Appendable.

If an IOException occurs when appending to the Appendable, an unchecked ICUUncheckedIOException is thrown instead.

Parameters
appendable A: The Appendable to which to append the string output.

Returns
A The same Appendable, for chaining.

charAt

Added in API level 30
public char charAt (int index)

Returns the char value at the specified index. An index ranges from zero to length() - 1. The first char value of the sequence is at index zero, the next at index one, and so on, as for array indexing.

If the char value specified by the index is a surrogate, the surrogate value is returned.

Parameters
index int: the index of the char value to be returned

Returns
char the specified char value

equals

Added in API level 30
public boolean equals (Object other)

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

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
other Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getFirstBigDecimal

Added in API level 30
public BigDecimal getFirstBigDecimal ()

Export the first formatted number as a BigDecimal. This endpoint is useful for obtaining the exact number being printed after scaling and rounding have been applied by the number range formatting pipeline.

Returns
BigDecimal A BigDecimal representation of the first formatted number.

getIdentityResult

Added in API level 30
public NumberRangeFormatter.RangeIdentityResult getIdentityResult ()

Returns whether the pair of numbers was successfully formatted as a range or whether an identity fallback was used. For example, if the first and second number were the same either before or after rounding occurred, an identity fallback was used.

Returns
NumberRangeFormatter.RangeIdentityResult A RangeIdentityType indicating the resulting identity situation in the formatted number range.

getSecondBigDecimal

Added in API level 30
public BigDecimal getSecondBigDecimal ()

Export the second formatted number as a BigDecimal. This endpoint is useful for obtaining the exact number being printed after scaling and rounding have been applied by the number range formatting pipeline.

Returns
BigDecimal A BigDecimal representation of the second formatted number.

hashCode

Added in API level 30
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
int a hash code value for this object.

length

Added in API level 30
public int length ()

Returns the length of this character sequence. The length is the number of 16-bit chars in the sequence.

Returns
int the number of chars in this sequence

nextPosition

Added in API level 31
public boolean nextPosition (ConstrainedFieldPosition cfpos)

Iterates over field positions in the FormattedValue. This lets you determine the position of specific types of substrings, like a month or a decimal separator. To loop over all field positions:

     ConstrainedFieldPosition cfpos = new ConstrainedFieldPosition();
     while (fmtval.nextPosition(cfpos)) {
         // handle the field position; get information from cfpos
     }
 

Parameters
cfpos ConstrainedFieldPosition: The object used for iteration state. This can provide constraints to iterate over only one specific field; see ConstrainedFieldPosition#constrainField.

Returns
boolean true if a new occurrence of the field was found; false otherwise.

subSequence

Added in API level 30
public CharSequence subSequence (int start, 
                int end)

Returns a CharSequence that is a subsequence of this sequence. The subsequence starts with the char value at the specified index and ends with the char value at index end - 1. The length (in chars) of the returned sequence is end - start, so if start == end then an empty sequence is returned.

Parameters
start int: the start index, inclusive

end int: the end index, exclusive

Returns
CharSequence the specified subsequence

toCharacterIterator

Added in API level 30
public AttributedCharacterIterator toCharacterIterator ()

Exports the formatted number as an AttributedCharacterIterator.

Consider using nextPosition(ConstrainedFieldPosition) if you are trying to get field information.

Returns
AttributedCharacterIterator An AttributedCharacterIterator containing full field information.

toString

Added in API level 30
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.
