Hi folks
Having some trouble making ASTs using a custom node type. Before I ask any
stupid questions, what is the best place to look on how to do this ( I'm using
3.2 )? I'm finding bits and pieces, some of them contradictory. For example I
find this example
static class V extends CommonTree {
public int x,y,z;
public V(int ttype, int x, int y, int z) {
this.x=x; this.y=y; this.z=z; token=new CommonToken(ttype,"");
}
at http://www.antlr.org/wiki/display/ANTLR3/Tree+construction
When I try to define a constructor like this I'm forced to put a cast between
on CommonToken to Token, which causes a runtime can't cast error.
What I want is really quite simple. Need to add one extra field to my AST
nodes to carry DSL type information.
Any help appreciated. Thanks.
