|
| - *
|
| - * <code>UnicodeFilter</code> defines a protocol for selecting a
|
| - * subset of the full range (U+0000 to U+10FFFF) of Unicode characters.
|
| - * Currently, filters are used in conjunction with classes like {@link
|
| - * Transliterator} to only process selected characters through a
|
| - * transformation.
|
| - *
|
| - * <p>Note: UnicodeFilter currently stubs out two pure virtual methods
|
| - * of its base class, UnicodeMatcher. These methods are toPattern()
|
| - * and matchesIndexValue(). This is done so that filter classes that
|
| - * are not actually used as matchers -- specifically, those in the
|
| - * UnicodeFilterLogic component, and those in tests -- can continue to
|
| - * work without defining these methods. As long as a filter is not
|
| - * used in an RBT during real transliteration, these methods will not
|
| - * be called. However, this breaks the UnicodeMatcher base class
|
| - * protocol, and it is not a correct solution.
|
| - *
|
| - * <p>In the future we may revisit the UnicodeMatcher / UnicodeFilter
|
| - * hierarchy and either redesign it, or simply remove the stubs in
|
| - * UnicodeFilter and force subclasses to implement the full
|
| - * UnicodeMatcher protocol.
