FormattedValue

public interface FormattedValue
implements CharSequence

android.icu.text.FormattedValue


An abstract formatted value: a string with associated field attributes. Many formatters format to classes implementing FormattedValue.

Summary

Public methods

abstract <A extends Appendable> A appendTo(A appendable)

Appends the formatted string to an Appendable.

abstract boolean nextPosition(ConstrainedFieldPosition cfpos)

Iterates over field positions in the FormattedValue.

abstract AttributedCharacterIterator toCharacterIterator()

Exports the formatted number as an AttributedCharacterIterator.

abstract String toString()

Returns the formatted string as a Java String.

Inherited methods

Public methods

appendTo

Added in API level 31
public abstract 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.

Throws
ICUUncheckedIOException if the Appendable throws IOException

nextPosition

Added in API level 31
public abstract 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.

toCharacterIterator

Added in API level 31
public abstract 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 31
public abstract String toString ()

Returns the formatted string as a Java String. Consider using appendTo(A) for greater efficiency.

Returns
String The formatted string.
