Hello everyone,
Is there an (easy) way to skip a subtree in a tree grammar? For
example in a conditional expression:
if bool_exp {
// Whatever is here should be skipped
}
---
--- from the tree grammar:
---
bool_function_content[Boolean value]
: {value != null && value.booleanValue()}? => function_content*
;
catch [FailedPredicateException e] {
BufferedTreeNodeStream commonInput = (BufferedTreeNodeStream)
input;
// This is what I had in mind, but how to skip the
current subtree?
}
I found the link
http://www.antlr.org/wiki/display/ANTLR3/6.+Advanced+processing , but
unfortunately that is about parser grammars. The incoming Boolean
value in bool_function_content already contains what to do (true means
evaluate and execute function_content*, false is skip the content).
Thanks a lot for your time!
Martijn
