term.

disambiguate
public Node disambiguate(AmbiguityRemover ar)
throws SemanticException
- Description copied from interface:
NodeOps
- Remove any remaining ambiguities from the AST.
This method is called by the
leave()
method of the
visitor. The method should perform work that should be done
after visiting the children of the node. The method may return
this
or a new copy of the node which will be
installed as a child of the node's parent.
The node should not assume that its children have been disambiguated.
If it depends on a child being disambiguated,
it may just return this
without doing any work.
- Specified by:
disambiguate
in interface NodeOps
- Overrides:
disambiguate
in class Node_c
- Parameters:
ar
- The visitor which disambiguates.
- Throws:
SemanticException
typeCheck
public Node typeCheck(TypeChecker tc)
throws SemanticException
- Description copied from class:
Assign_c
- Type check the expression.
- Specified by:
typeCheck
in interface NodeOps
- Overrides:
typeCheck
in class Assign_c
- Throws:
SemanticException
