public JvmCfaNode(MethodSignature signature,
                  int offset,
                  Clazz clazz)
```
    Create a JVM CFA node without edges. Since in most cases we expect to have just one element in the lists of leaving and entering edges the lists are initialized with size 1.
    
    Parameters:
    
    signature - the signature of the method the node belongs to
    
    offset - a number indicating the program location offset of the node
    
    clazz - the class of the method the node belongs to
  - JvmCfaNode
```
public JvmCfaNode(java.util.List<JvmCfaEdge> leavingEdges,

                  int offset,
                  Clazz clazz)
```
    Create JVM CFA node with the specified entering and exiting edges.
    
    Parameters:
    
    leavingEdges - a list of edges leaving the node
    
    enteringEdges - a list of edges entering the node
    
    signature - the signature of the method the node belongs to
    
    offset - a number indicating the program location offset of the node
