All Implemented Interfaces:

CfaNode<JvmCfaEdge,MethodSignature>

public class JvmCatchCfaNode
extends JvmCfaNode

A JvmCfaNode representing the beginning of a catch or finally block.

The finally blocks are identified by catch type 0.

JvmCatchCfaNode

public JvmCatchCfaNode(MethodSignature signature,
 int offset,
 int catchType,
 Clazz clazz)

Create a JVM CFA catch 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

catchType - an integer representing the exception type caught by the handler in the node's method exception table

clazz - the class of the method the node belongs to

JvmCatchCfaNode

public JvmCatchCfaNode(List<JvmCfaEdge> leavingEdges,
 List<JvmCfaEdge> enteringEdges,
 MethodSignature signature,
 int offset,
 int catchType,
 Clazz clazz)

Create JVM CFA catch 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

catchType - an integer representing the exception type caught by the handler in the node's method exception table

clazz - the class of the method the node belongs to

Method Details

getCatchType

public int getCatchType()

Returns the integer representing the exception type in the exception table of the method the node belongs to.

isFinallyNode

public boolean isFinallyNode()

Returns true if the catch node represents the beginning of a finally block.
