All Implemented Interfaces:

TreeVisitor<Node,Void>

Direct Known Subclasses:

CFCFGBuilder.CFCFGTranslationPhaseOne
```
public class CFGTranslationPhaseOne
extends TreePathScanner<Node,Void>
```
Class that performs phase one of the translation process. It generates the following information:
- A sequence of extended nodes.
- A set of bindings from Labels to positions in the node sequence.
- A set of leader nodes that give rise to basic blocks in phase two.
- A lookup map that gives the mapping from AST tree nodes to Nodes.
The return type of this scanner is Node. For expressions, the corresponding node is returned to allow linking between different nodes.
However, for statements there is usually no single Node that is created, and thus no node is returned (rather, null is returned).
Every visit* method is assumed to add at least one extended node to the list of nodes (which might only be a jump).

    Given a method element and as list of argument expressions, return a list of Nodes representing the arguments converted for a call of the method. This method applies to both method invocations and constructor calls.
    
    Parameters:
    
    method - an ExecutableElement representing a method to be called
    
    actualExprs - a List of argument expressions to a call
    
    Returns:
    
    a List of Nodes representing arguments after conversions required by a call to this method
