- Method Detail
  - getMethod
```
IMethod getMethod()
```
    Return the method this CGNode represents. This value will never be null.
    
    Returns:
    
    the target IMethod for this CGNode.
  - getContext
```
Context getContext()
```
    Return the context this CGNode represents. This value will never be null.
    
    Returns:
    
    the Context for this CGNode.
  - addTarget
```
@Deprecated
boolean addTarget(CallSiteReference site,
                  CGNode target)
```
    Deprecated.
    
    This is for use only by call graph builders ... not by the general public. Clients should not use this. Record that a particular call site might resolve to a call to a particular target node. Returns true if this is a new target
  - getIR
```
IR getIR()
```
    Returns:
    
    the "default" IR for this node used by the governing call graph
  - getDU
```
DefUse getDU()
```
    Returns:
    
    DefUse for the "default" IR for this node used by the governing call graph
  - iterateNewSites
```
Iterator<NewSiteReference> iterateNewSites()
```
    Returns:
    
    an Iterator of the types that may be allocated by a given method in a given context.
  - iterateCallSites
```
Iterator<CallSiteReference> iterateCallSites()
```
    Returns:
    
    an Iterator of the call statements that may execute in a given method for a given context
