                  NodeFactory nf)

Method Detail

enterCall

protected NodeVisitor enterCall(Node n)
                         throws SemanticException

Overrides:

enterCall in class ErrorHandlingVisitor

Throws:

SemanticException

leaveCall

protected Node leaveCall(Node parent,
             Node old,
             Node n,
             NodeVisitor v)
                  throws SemanticException

Description copied from class: ErrorHandlingVisitor

Contains all of the functionality that can be done in the leave method, but allows SemanticExceptions to be thrown. This method is in addition to the leave method, and allows the compiler writer to write code that can throw errors and let the Polyglot infrastructure handle the exceptions.

Overrides:

leaveCall in class ErrorHandlingVisitor

old - The original state of root of the current subtree.

n - The current state of the root of the current subtree.

v - The NodeVisitor object used to visit the children.

Returns:

The final result of the traversal of the tree rooted at n.

Throws:

SemanticException

isExtendedFor

protected boolean isExtendedFor(Node n)

freshName

protected java.lang.String freshName(java.lang.String desc)

translateExtForArray

                        java.util.List<java.lang.String> labels)
                             throws SemanticException

Throws:

SemanticException
