    • Method Detail

      • values

        public static Duplication.WithFlip[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (Duplication.WithFlip c : Duplication.WithFlip.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static Duplication.WithFlip valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.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.
