FormattedNumberRange
open class FormattedNumberRange : FormattedValue
kotlin.Any | |
↳ | 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.

Public methods
appendTo
open fun <A : Appendable!> appendTo(appendable: A): A
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. |
Return | |
---|---|
A |
The same Appendable, for chaining. |
Exceptions | |
---|---|
android.icu.util.ICUUncheckedIOException |
if the Appendable throws IOException |
equals
open fun equals(other: Any?): Boolean
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 returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
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 | |
---|---|
obj |
the reference object with which to compare. |
Return | |
---|---|
Boolean |
true if this object is the same as the obj argument; false otherwise. |
get
open fun get(index: Int): Char
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 |
Return | |
---|---|
Char |
the specified char value |
Exceptions | |
---|---|
java.lang.IndexOutOfBoundsException |
if the index argument is negative or not less than length() |
getFirstBigDecimal
open fun getFirstBigDecimal(): BigDecimal!
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.
Return | |
---|---|
BigDecimal! |
A BigDecimal representation of the first formatted number. |
getIdentityResult
open fun getIdentityResult(): NumberRangeFormatter.RangeIdentityResult!
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.
Return | |
---|---|
NumberRangeFormatter.RangeIdentityResult! |
A RangeIdentityType indicating the resulting identity situation in the formatted number range. |
getSecondBigDecimal
open fun getSecondBigDecimal(): BigDecimal!
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.
Return | |
---|---|
BigDecimal! |
A BigDecimal representation of the second formatted number. |
hashCode
open fun hashCode(): Int
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.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 inequals
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 thehashCode
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 thehashCode
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.
Return | |
---|---|
Int |
a hash code value for this object. |
nextPosition
open fun nextPosition(cfpos: ConstrainedFieldPosition!): Boolean
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 . |
Return | |
---|---|
Boolean |
true if a new occurrence of the field was found; false otherwise. |
subSequence
open fun subSequence(
startIndex: Int,
endIndex: Int
): CharSequence
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 char
s) of the returned sequence is end - start
, so if start == end
then an empty sequence is returned.
Parameters | |
---|---|
start |
the start index, inclusive |
end |
the end index, exclusive |
Return | |
---|---|
CharSequence |
the specified subsequence |
Exceptions | |
---|---|
java.lang.IndexOutOfBoundsException |
if start or end are negative, if end is greater than length() , or if start is greater than end |
toCharacterIterator
open fun toCharacterIterator(): AttributedCharacterIterator!
Exports the formatted number as an AttributedCharacterIterator.
Consider using nextPosition
if you are trying to get field information.
Return | |
---|---|
AttributedCharacterIterator! |
An AttributedCharacterIterator containing full field information. |
toString
open fun toString(): String
Returns a string representation of the object.
Return | |
---|---|
String |
The formatted string. |
Properties
length
open val length: Int
Returns the length of this character sequence. The length is the number of 16-bit char
s in the sequence.
Return | |
---|---|
Int |
the number of char s in this sequence |
