Method Detail

getInstance

public static BytecodeInstructionPool getInstance(ClassLoader classLoader)

registerMethodNode

public List<BytecodeInstruction> registerMethodNode(org.objectweb.asm.tree.MethodNode node,
                                                    String className,
                                                    String methodName)

Called by each CFGGenerator for it's corresponding method. The MethodNode contains all instructions within a method. A call to registerMethodNode() fills the instructionMap of the BytecodeInstructionPool with the instructions in that method and returns a List containing the BytecodeInstructions within that method. While registering all instructions the lineNumber of each BytecodeInstruction is set.

Parameters:

node - a MethodNode object.

className - a String object.

methodName - a String object.

Returns:

a List object.

registerInstruction

public void registerInstruction(BytecodeInstruction instruction)

registerInstruction

Parameters:

instruction - a BytecodeInstruction object.

getInstruction

public BytecodeInstruction getInstruction(String className,
                                          String methodName,
