find

public org.antlr.v4.runtime.tree.ParseTree find(org.antlr.v4.runtime.tree.ParseTree from,
 Predicate<org.antlr.v4.runtime.tree.ParseTree> target,
 Predicate<org.antlr.v4.runtime.tree.ParseTree> stopAt)

The nearest strict ancestor of from that satisfies target, or null. An ancestor that satisfies stopAt ends the ascent (null) before it is offered to target.
