An API for QueryPart.$replace(Replacer) query part transformations.

• #supplier()
• #abort()
• recurse()
• #before()
• #after()
• #finisher()

Method Summary

Modifier and Type	Method	Description
static Replacer	of(Function<? super QueryPart,? extends QueryPart> replacer)	Convenience method to create a Replacer with a replacer().
static Replacer	of(Predicate<? super QueryPart> recurse, Function<? super QueryPart,? extends QueryPart> replacer)	Convenience method to create a Replacer with a recurse() and replacer().
Predicate<QueryPart>	recurse()	An optional recursion condition to prevent entering a specific subtree, e.g.
Function<QueryPart,QueryPart>	replacer()	A callback that is invoked on all elements of the QueryPart expression tree.
