Enum Class Removal

java.lang.Object
java.lang.Enum<Removal>
net.bytebuddy.implementation.bytecode.Removal
All Implemented Interfaces:
Serializable, Comparable<Removal>, Constable, StackManipulation

public enum Removal extends Enum<Removal> implements StackManipulation
Removes a value from the operand stack.
  • Enum Constant Details

    • ZERO

      public static final Removal ZERO
      A removal of no value. This corresponds a no-op instruction.
    • SINGLE

      public static final Removal SINGLE
      A removal of a single-sized value.
    • DOUBLE

      public static final Removal DOUBLE
      A removal of a double-sized value.
  • Field Details

    • size

      private final StackManipulation.Size size
      The size impact of the removal onto the operand stack.
    • opcode

      private final int opcode
      The opcode to execute for the removal.
  • Constructor Details

    • Removal

      private Removal(StackSize stackSize, int opcode)
      Creates a new removal stack manipulation.
      Parameters:
      stackSize - The size impact of the removal onto the operand stack.
      opcode - The opcode to execute for the removal.
  • Method Details

    • values

      public static Removal[] 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 Removal 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
    • of

      public static StackManipulation of(TypeDefinition typeDefinition)
      Removes a value from the operand stack dependant of its size.
      Parameters:
      typeDefinition - The type to remove from the stack.
      Returns:
      A stack manipulation that represents the removal.
    • 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.
