argumentStack

private int argumentStack

Stack used to keep track of class types that have arguments. Each element of this stack is a boolean encoded in one bit. The top of the stack is the lowest order bit. Pushing false = *2, pushing true = *2+1, popping = /2.

arrayStack

private int arrayStack

Stack used to keep track of array class types. Each element of this stack is a boolean encoded in one bit. The top of the stack is the lowest order bit. Pushing false = *2, pushing true = *2+1, popping = /2.
