Class ControlFlowGraph

public class ControlFlowGraph extends Object

This class represents a control flow graph of a method.

Constructor Summary
	ControlFlowGraph(MethodGen method_gen) A Control Flow Graph.

Method Summary
InstructionContext	contextOf(InstructionHandle inst) Returns the InstructionContext of a given instruction.
InstructionContext[]	contextsOf(InstructionHandle[] insts) Returns the InstructionContext[] of a given InstructionHandle[], in a naturally ordered manner.
InstructionContext[]	getInstructionContexts() Returns an InstructionContext[] with all the InstructionContext instances for the method whose control flow is represented by this ControlFlowGraph (NOT ORDERED!)
boolean	isDead(InstructionHandle i) Returns true, if and only if the said instruction is not reachable; that means, if it is not part of this ControlFlowGraph.
