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. |

Public methods
appendTo
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
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
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
public abstract String toString ()
Returns the formatted string as a Java String. Consider using appendTo(A) for greater efficiency.
| Returns | |
|---|---|
String | The formatted string. |
