      public static final DefaultValue DOUBLE
      The default value of a double.
    • VOID

      public static final DefaultValue VOID
      The default value of a void which resembles a no-op manipulation.
    • REFERENCE

      public static final DefaultValue REFERENCE
      The default value of a reference type which resembles the null reference.
  • Field Details

    • stackManipulation

      private final StackManipulation stackManipulation
      The stack manipulation that represents the loading of a given default value onto the operand stack.
  • Constructor Details

    • DefaultValue

      private DefaultValue(StackManipulation stackManipulation)
      Creates a new default value load operation.
      Parameters:
      stackManipulation - The stack manipulation that represents the loading of a given default value onto the operand stack.
  • Method Details

    • values

      public static DefaultValue[] 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 DefaultValue 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
    • of

      public static StackManipulation of(TypeDefinition typeDefinition)
      Creates a stack assignment that loads the default value for a given type.
      Parameters:
      typeDefinition - The type for which a default value should be loaded onto the operand stack.
      Returns:
      A stack manipulation loading the default value for the given type.
    • 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.
