Class FormattedValueStringBuilderImpl

java.lang.Object

org.graalvm.shadowed.com.ibm.icu.impl.FormattedValueStringBuilderImpl

public class FormattedValueStringBuilderImpl
extends Object

Implementation of FormattedValue based on FormattedStringBuilder. The implementation currently revolves around numbers and number fields. However, it can be generalized in the future when there is a need. In C++, this implements FormattedValue. In Java, it is a stateless collection of static functions to avoid having to use nested objects.

public FormattedValueStringBuilderImpl()

Method Detail

findSpan

public static int findSpan(FormattedStringBuilder self,
                           Object value)

Finds the index at which a span field begins.

Parameters:

value - The value of the span field to search for.

Returns:

The index, or -1 if not found.

applySpanRange

public static void applySpanRange(FormattedStringBuilder self,
                                  UFormat.SpanField spanField,
                                  Object value,
                                  int start,
                                  int end)

Upgrade a range of a string to a span field. Similar to appendSpanInfo in ICU4C.

nextFieldPosition

public static boolean nextFieldPosition(FormattedStringBuilder self,
                                        FieldPosition fp)

toCharacterIterator

public static AttributedCharacterIterator toCharacterIterator(FormattedStringBuilder self,
                                                              Format.Field numericField)

nextPosition

public static boolean nextPosition(FormattedStringBuilder self,
                                   ConstrainedFieldPosition cfpos,
                                   Format.Field numericField)

Implementation of nextPosition consistent with the contract of FormattedValue.

Parameters:

cfpos - The argument passed to the public API.

numericField - Optional. If non-null, apply this field to the entire numeric portion of the string.

Returns:

See FormattedValue#nextPosition.
