Class JumpInsnNode


  • public class JumpInsnNode
    extends AbstractInsnNode
    A node that represents a jump instruction. A jump instruction is an instruction that may jump to another instruction.
    • Field Detail

      • label

        public LabelNode label
        The operand of this instruction. This operand is a label that designates the instruction to which this instruction may jump.

      • JumpInsnNode

        public JumpInsnNode​(int opcode,
                            LabelNode label)
        Constructs a new JumpInsnNode.
        Parameters:
        opcode - the opcode of the type instruction to be constructed. This opcode must be IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.
        label - the operand of the instruction to be constructed. This operand is a label that designates the instruction to which the jump instruction may jump.

      • setOpcode

        public void setOpcode​(int opcode)
        Sets the opcode of this instruction.
        Parameters:
        opcode - the new instruction opcode. This opcode must be IFEQ, IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.
      • getType

        public int getType()
        Description copied from class: AbstractInsnNode
        Returns the type of this instruction.
        Specified by:
        getType in class AbstractInsnNode
        Returns:
        the type of this instruction, i.e. one the constants defined in this class.
      • accept

        public void accept​(MethodVisitor methodVisitor)
        Description copied from class: AbstractInsnNode
        Makes the given method visitor visit this instruction.
        Specified by:
        accept in class AbstractInsnNode
        Parameters:
        methodVisitor - a method visitor.
