firstChild
public Term firstChild()
- Description copied from interface:
Term
- Return the first direct subterm performed when evaluating this term. If
this term has no subterms, this should return null.
This method is similar to the deprecated entry(), but it should *not*
recursively drill down to the innermost subterm. The direct child visited
first in this term's dataflow should be returned.
- Specified by:

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
- Parameters:
tc
- The type checking visitor.
- Throws:
SemanticException
copy
public Node copy(NodeFactory nf)
- Description copied from interface:
NodeOps
- Produce a copy of this node using the given NodeFactory.
- Specified by:
copy
in interface NodeOps
- Overrides:
copy
in class Assign_c
