Sequence	eval(Sequence contextSequence) Execute the compiled query, optionally using the specified sequence as context.
XQueryContext	getContext()
XACMLSource	getSource() Gets the source of this query.
boolean	isValid() Is the compiled expression still valid? Returns false if, for example, the source code of one of the imported modules has changed.
void	reset() Reset the compiled expression tree.
void	setContext(XQueryContext context)
void	setSource(XACMLSource source) Sets the source of this query.
