    • Method Detail

      • contextsOf

        public InstructionContext[] contextsOf​(InstructionHandle[] insts)
        Returns the InstructionContext[] of a given InstructionHandle[], in a naturally ordered manner.
      • getInstructionContexts

        public InstructionContext[] getInstructionContexts()
        Returns an InstructionContext[] with all the InstructionContext instances for the method whose control flow is represented by this ControlFlowGraph (NOT ORDERED!).
      • isDead

        public 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.
