Class CharacterIteratorFieldDelegate

java.lang.Object
  java.text.CharacterIteratorFieldDelegate

All Implemented Interfaces:

Format.FieldDelegate

class CharacterIteratorFieldDelegate

extends Object

implements Format.FieldDelegate

CharacterIteratorFieldDelegate combines the notifications from a Format into a resulting AttributedCharacterIterator. The resulting AttributedCharacterIterator can be retrieved by way of the getIterator method.

Field Summary

private ArrayList	attributedStrings Array of AttributeStrings.
private int	size Running count of the number of characters that have been encountered.

Constructor Summary

(package private)

CharacterIteratorFieldDelegate()

Method Summary

void	formatted(Format.Field attr, Object value, int start, int end, StringBuffer buffer) Notified when a particular region of the String is formatted.
void	formatted(int fieldID, Format.Field attr, Object value, int start, int end, StringBuffer buffer) Notified when a particular region of the String is formatted.
AttributedCharacterIterator	getIterator(String string) Returns an AttributedCharacterIterator that can be used to iterate over the resulting formatted String.

Field Detail

attributedStrings

private ArrayList attributedStrings

Array of AttributeStrings. Whenever formatted is invoked for a region > size, a new instance of AttributedString is added to attributedStrings. Subsequent invocations of formatted for existing regions result in invoking addAttribute on the existing AttributedStrings.

size

private int size

Running count of the number of characters that have been encountered.

Method Detail

formatted

public void formatted(Format.Field attr,
                      Object value,
                      int start,
                      int end,
                      StringBuffer buffer)

Description copied from interface: Format.FieldDelegate

Notified when a particular region of the String is formatted. This method will be invoked if there is no corresponding integer field id matching attr.

Specified by:

formatted in interface Format.FieldDelegate

Parameters:

attr - Identifies the field matched

value - Value associated with the field

start - Beginning location of the field, will be >= 0

end - End of the field, will be >= start and <= buffer.length()

buffer - Contains current formatted value, receiver should NOT modify it.

formatted

public void formatted(int fieldID,
                      Format.Field attr,
                      Object value,
                      int start,
                      int end,
                      StringBuffer buffer)

Description copied from interface: Format.FieldDelegate

Notified when a particular region of the String is formatted.

Specified by:

formatted in interface Format.FieldDelegate

Parameters:

fieldID - Identifies the field by integer

attr - Identifies the field matched

value - Value associated with the field

start - Beginning location of the field, will be >= 0

end - End of the field, will be >= start and <= buffer.length()

buffer - Contains current formatted value, receiver should NOT modify it.

getIterator

public AttributedCharacterIterator getIterator(String string)

Returns an AttributedCharacterIterator that can be used to iterate over the resulting formatted String.
