Method Detail

enterScope

public Context enterScope(Context c)

A SwitchBlock differs from a normal block in that declarations made in the context of the switch block are in the scope following the switch block. For example

 switch (i) { 
     case 0: 
       int i = 4; 
     case 1: 
       // i is in scope, but may not have been initialized.
     ...
 } 
 

Specified by:

enterScope in interface NodeOps

Overrides:

enterScope in class AbstractBlock_c

Parameters:

c - the current Context

Returns:

the Context to be used for visiting this node.

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 Node_c
