Imports
org.antlr.v4.runtime.misc.IntegerStack, java.util.ArrayDeque, .Deque
An iterative (read: non-recursive) pre-order and post-order tree walker that doesn't use the thread stack but heap-based stacks. Makes it possible to process deeply nested parse trees.

Doc from org.antlr.v4.runtime.tree.ParseTreeWalker.walk.

Performs a walk on the given parse tree starting at the root and going down recursively with depth-first search. On each node, ParseTreeWalker#enterRule is called before recursively walking down into child nodes, then ParseTreeWalker#exitRule is called after the recursive call to wind up.

Parameters
listener:ParseTreeListener

The listener used by the walker to process grammar rules

t:ParseTree

The parse tree to be walked on
