    • INTEGER

      public static final Subtraction INTEGER
      Subtracts two integers or integer-compatible values.
    • LONG

      public static final Subtraction LONG
      Subtracts two longs.
    • FLOAT

      public static final Subtraction FLOAT
      Subtracts two floats.
    • DOUBLE

      public static final Subtraction DOUBLE
      Subtracts two doubles.
  • Field Details

    • opcode

      private final int opcode
      The opcode to apply.
    • stackSize

      private final StackSize stackSize
      The stack size of the subtracted primitive.
  • Constructor Details

    • Subtraction

      private Subtraction(int opcode, StackSize stackSize)
      Creates a new subtraction.
      Parameters:
      opcode - The opcode to apply.
      stackSize - The stack size of the subtracted primitive.
  • Method Details

    • values

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

      public static Subtraction valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class 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.
