public enum ShiftLeft extends Enum<ShiftLeft> implements StackManipulation
A stack manipulation that shifts left two numbers on the operand stack.
  • Enum Constant Details

    • INTEGER

      public static final ShiftLeft INTEGER
      Shifts left two integers or integer-compatible values.
    • LONG

      public static final ShiftLeft LONG
      Shifts left two longs.
  • Field Details

    • opcode

      private final int opcode
      The opcode to apply.
    • stackSize

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

    • ShiftLeft

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

    • values

      public static ShiftLeft[] 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 ShiftLeft 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.
