      Negates a long.
    • FLOAT

      public static final Negation FLOAT
      Negates a float.
    • DOUBLE

      public static final Negation DOUBLE

  • Field Details

    • opcode

      private final int opcode
      The opcode to apply.
  • Constructor Details

    • Negation

      private Negation(int opcode)
      Creates a new negation.
      Parameters:
      opcode - The opcode to apply.
  • Method Details

    • values

      public static Negation[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared
    • valueOf

      public static Negation valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
    • isValid

      public boolean isValid()
      Determines if this stack manipulation is valid.
      Specified by:
      isValid in interface StackManipulation
      Returns:
      If false, this manipulation cannot be applied and should throw an exception.
    • apply

      public StackManipulation.Size apply(org.objectweb.asm.MethodVisitor methodVisitor, Implementation.Context implementationContext)
      Applies the stack manipulation that is described by this instance.
      Specified by:
      apply in interface StackManipulation
      Parameters:
      methodVisitor - The method visitor used to write the method implementation to.
      implementationContext - The context of the current implementation.
      Returns:
      The changes to the size of the operand stack that are implied by this stack manipulation.
