Hello list,
My tree grammar looks as follow's:-
edges[Object g,String subID] returns [int nodeID] @init { nodeID= 0; } :
{ int edgeID = 0; }
( ^(D_EDGE_OP ( start=edges[g,subID] | start=node_id[g,subID] )
end=node_id[g,subID]
{
}
node_id[Object g,String subID] returns [int nodeID] @init { nodeID=0;}
:
( i=id
| ^(COLON i=id (r=ID) ? ( compass ) ? )
) {}
Simply put, *Can I get text of a next matched token using a grammar
action*. *Lookahead K=1 for example*.
Further description:-
For this sample edge cluster_A --> B, in the edges function,
start=node_id[g,subID] is the first match.
How do I do something like this, ( ^(D_EDGE_OP ( start=edges[g,subID] |
start=node_id[g,subID] (get value of matched id in node_id func here)
end=node_id[g,subID]
That is, I want to get the id of the matched node(which is obvious
node_id func) in the edges function.
