[antlr-interest] Tree construction - Adding subtrees

[Stephen Tuttlebee]

One last attempt to make the code display better:

componentDefinition
:  ^(COMPONENT_DEF IDENTIFIER ^(BOUNDARY_DECLS boundaryDeclaration*) 
^(FIELD_DECLS fieldDeclaration*) runMethodDeclaration* ^(HANDLER_DECLS 
handlerDeclaration*) ^(METHOD_DECLS methodDeclaration*))

{ ... some actions here you can ignore... }

-> ^(COMPONENT_DEF IDENTIFIER ^(BOUNDARY_DECLS boundaryDeclaration*) 
^(FIELD_DECLS fieldDeclaration*) runMethodDeclaration*

   ^(HANDLER_DECLS handlerDeclaration*
   {
   for(String boundaryName : boundariesWithNoHandler) {
     // .... calculate/get values to put in subtree ...

     /* I want to be able to use ANTLR's friendly tree construction 
syntax here somehow whilst in the middle of this action.
          Every iteration of the for loop creates a new subtree --- if I 
can't do it this way, what is the tree construction code I would need 
here? */
     ^(HANDLER_DECL {$boundaryName} ^(IDENT {$b.getType}) 
{$b.getDirectionString()} ^(BLOCK BLOCK_STATEMENT))
   } // end for
   }

   )  ^(METHOD_DECLS methodDeclaration*))
;

Hope that displays better.
