  - JvmCfaEdge
```
public JvmCfaEdge()
```
    Create a disconnected JVM CFA edge.
  - JvmCfaEdge
```
public JvmCfaEdge(JvmCfaNode source,
                  JvmCfaNode target)
```
    Create a JVM CFA edge. Also sets it as the entering and leaving edge of the source and target nodes.
    
    Parameters:
    
    source - the source node of the edge
    
    target - the target node of the edge
- Method Detail
  - getSource
```
public JvmCfaNode getSource()
```
    Description copied from interface: CfaEdge
    
    Returns its source node.
    
    Specified by:
    
    getSource in interface CfaEdge<JvmCfaNode>
  - getTarget
```
public JvmCfaNode getTarget()
```
    Description copied from interface: CfaEdge
    
    Returns its target node.
    
    Specified by:
    
    getTarget in interface CfaEdge<JvmCfaNode>
  - setSource
```
public void setSource(JvmCfaNode source)
```
    Sets a node as the predecessor of the edge and adds the edge as leaving edge of the node.
  - setTarget
```
public void setTarget(JvmCfaNode target)
```
    Sets a node as the successor of the edge and adds the edge as entering edge of the node.
  - targetSignature
```
public MethodSignature targetSignature()
```
    Returns the signature of the target method. This is the current method or, for call edges, the target method of the call.
