Examples of ICharacterPairMatcher

org.eclipse.jface.text.source.ICharacterPairMatcher
A character pair matcher finds to a character at a certain document offset the matching peer character. It is the matchers responsibility to define the concepts of "matching" and "peer". The matching process starts at a given offset. Starting of this offset, the matcher chooses a character close to this offset. The anchor defines whether the chosen character is left or right of the initial offset. The matcher then searches for the matching peer character of the chosen character and if it finds one, delivers the minimal region of the document that contains both characters.
In order to provide backward compatibility for clients of ICharacterPairMatcher, extension interfaces are used to provide a means of evolution. The following extension interface exists:
- {@link org.eclipse.jface.text.source.ICharacterPairMatcherExtension} since version 3.8introducing the concept of matching peer character and enclosing peer characters for a given selection.
Clients may implement this interface and its extension interface or use the default implementation provided by DefaultCharacterPairMatcher.
@see org.eclipse.jface.text.source.ICharacterPairMatcherExtension @since 2.1
