org.eclipse.jface.text.contentassist.IContentAssistProcessor.computeContextInformation()
Returns information about possible contexts based on the specified location within the document that corresponds to the current cursor position within the text viewer. @param viewer the viewer whose document is used to compute the possible contexts @param offset an offset within the document for which context information should be computed @return an array of context information objects or null if no context could be found
