All Implemented Interfaces:

org.eclipse.jface.text.ITextDoubleClickStrategy

public class LexerTokenAndCharacterPairAwareStrategy
extends AbstractWordAwareDoubleClickStrategy

This implementation uses the tokens of an Xtext document to identify words in the document. Thereby it recognizes keywords that consist only of characters that are no letters, e.g. += or ?=. Furthermore it will select the contents of a brace pair if the opening or closing peer is clicked. Tokens with a length of one character have a lower priority in case a token boundary is selected.
