Class TokenScanner.RangedReentrantIterator

java.lang.Object
  com.google.common.collect.UnmodifiableIterator<ILexerTokenRegion>
      org.eclipse.xtext.ui.editor.syntaxcoloring.TokenScanner.RangedReentrantIterator

All Implemented Interfaces:

java.util.Iterator<ILexerTokenRegion>

Enclosing class:

TokenScanner

protected class TokenScanner.RangedReentrantIterator
extends com.google.common.collect.UnmodifiableIterator<ILexerTokenRegion>

A reentrant iterator allows to reuse and filter the elements another iterator and may update its filter criteria continuously.

It is assumed that setRange(IDocument, int, int) will be called with ascending order most of the time thus a sorted iterator may be reused and traversed further after the range has been updated.
