[antlr-interest] How can I modify a tree node value according to the value of another tree node ?

[YINGAnnie]

Hi everyone,

 

 

What I want to do is to replace var t:Number=Math.ceil(1.5);  to  var t:int=int(1.5); The tree I got is something like this:

 

PROPERTY_DECL (VARIABLE_STATEMENT (VAR_DECL_LIST (VAR_ID_DECL t (QUALIFIED_NAME Number)) = (ASSIGNMENT_EXPRESSION (CONDITION_EXPRESSION (...........(QUALIFIED_NAME Math . ceil))) (ARGUMENT_SUFFIX (.........(PRIMARY_EXPRESSION 1.5))))

 

....... stands for some other nodes.

 

 

Replacing Math.ceil(1.5) to int(1.5) is easy to implement.But cos Number rule and Math.ceil rule belong to different tree, how can I replace Number to int when value of the other tree's node equals to Math.ceil? 

 

Thanks in advance!

 

 

Annie
