Direct Known Subclasses:

PlainTextBidiRegionsSeparator, TokenSetBidiRegionsSeparator

public abstract class BidiRegionsSeparator
extends java.lang.Object

Defines boundaries between regions for which bidi layout should be performed independently. This is required e.g. to make sure that programming language elements (e.g. identifiers) are not reordered visually even if they are named using RTL languages.

Currently it can be specified as a language-level extension (see LanguageBidiRegionsSeparator).

Default implementation assumes a border between any two tokens of different types.
