Method Summary

Modifier and Type	Method and Description
private void	collectAndNodes(AndPointcut apc, Set<Pointcut> nodesSoFar)
private void	collectOrNodes(Pointcut pc, Set<Pointcut> nodesSoFar)
public Pointcut	createAndsFor(Pointcut[] ps) Passed an array of pointcuts, returns an AND tree with them in.
private Pointcut	distributeNot(Pointcut pc)
public static String	format(Pointcut p) Allows formatting of the output pointcut for debugging...
private boolean	isAnd(Pointcut pc)
private boolean	isDNF(Pointcut pc) Check if a pointcut is in DNF - if it is then it should be lots of 'ORs' up the top with 'ANDs' beneath them.
private boolean	isDNFHelper(Pointcut pc, boolean canStillHaveOrs) Helper function for determining DNFness.
private boolean	isNot(Pointcut pc)
private boolean	isOr(Pointcut pc)
public Pointcut	not(Pointcut p) Returns a NOTted form of the pointcut p - we cope with already NOTted pointcuts.
private Pointcut	pullUpDisjunctions(Pointcut pc)
private Pointcut	removeNothings(Pointcut pc) Removes MATCHES_NOTHING pointcuts
public Pointcut	rewrite(Pointcut pc, boolean forceRewrite) Set forcerewrite if you want to override the checking for something already in DNF (useful for some testing) Repeated processing of something already in DNF is expensive (it ends up being done for every pointcut on every incremental compile) - so let's not do it if we don't have to.
