Hi Gurus, I'm a novice using ANTLR for a development project. I am at a stage where I need to rewrite AST so that the transformed AST renders itself more easy for me to walk and emit the translation that I need. In this context I've a concept question.
In general, can I use the *same* tree adapter, used by the InputNodeStream used by the walker, in a java method that I code to restructure the tree without using the rewrite rule? That is can I add, delete, replace nodes at will in the source tree? I am looking at this option as I need to move up a subtree from deep down to a much higher level. In particular would manipulating the source tree mess up the iterator used by the ANTLR AST walker to parse the tree? (eg) Just want to know if I can effect this in JAVA. I am sure we can make it happen using rewrite rule. However I want to conceptually know if what I desire above is a feasibility or it it a totally wrong approach. ^(ROOT a b ^(ROOT c d ^(ROOT e f g))) I need to restructure the tree like, say, ^(ROOT a b ^(ROOT c d ) ^(ROOT e f g)) Based on your input I need to chalk the future course of my coding. Thanks in advance.
