public class InputMethodHighlight

extends Object

A InputMethodHighlight is used to describe in an abstract way the highlight attributes of text being composed. A range of text can be selected or unselected, and it can be highlighted in different ways to indicate the conversion state or other interesting, input method specific information about the text. Two states are predefined and supported directly by Graphics2D: raw (unconverted) and converted text. These styles are recommended for use before and after the main conversion step of text composition, say, before and after kana->kanji or pinyin->hanzi conversion. However, input methods can add their own style variations as necessary. InputMethodHighlight instances are typically used as attribute values returned from AttributedCharacterIterator for the INPUT_METHOD_HIGHLIGHT attribute.
