visitChildren
public Node visitChildren(NodeVisitor v)
- Description copied from interface:
NodeOps
- Visit the children of the node.
- Specified by:
visitChildren
in interface NodeOps
- Overrides:
visitChildren
in class Node_c
- Parameters:
v
- The visitor that will traverse/rewrite the AST.
- Returns:
- A new AST if a change was made, or
this
.
typeCheck
public Node typeCheck(TypeChecker tc)
throws SemanticException
- Description copied from interface:
NodeOps
- Type check 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.
- Specified by:
typeCheck
in interface NodeOps
- Overrides:
typeCheck
in class Node_c
- Parameters:
tc
- The type checking visitor.
- Throws:
SemanticException

.
- Specified by:
translate
in interface NodeOps
- Overrides:
