newPosition

protected LightweightPosition newPosition(int offset,
                                          int length,
                                          int timestamp,
                                          java.lang.String... ids)

newPosition

protected LightweightPosition newPosition(int offset,
                                          int length,
                                          int timestamp,
                                          LightweightPosition.IntToStringArray[] ids)

provideHighlightingFor

public void provideHighlightingFor(org.eclipse.xtext.resource.XtextResource resource,
                                   IHighlightedPositionAcceptor acceptor,
                                   org.eclipse.xtext.util.CancelIndicator cancelIndicator)

Specified by:

Parameters:

resource - the resource that will be highlighted. May be null in some rare cases.

acceptor - used to announce the mapping from text-range to the style's id. The acceptor will never be null.

cancelIndicator - used to determine whether we should stop searching for highlighting positions (use OperationCanceledManager to check)
