Enum Constant Detail

SINGLE_SINGLE

public static final Duplication.WithFlip SINGLE_SINGLE

A flip instruction that flips a single-sized element over another single-size element.

SINGLE_DOUBLE

public static final Duplication.WithFlip SINGLE_DOUBLE

A flip instruction that flips a double-sized element over a single-size element.

DOUBLE_SINGLE

public static final Duplication.WithFlip DOUBLE_SINGLE

A flip instruction that flips a single-sized element over a double-size element.

DOUBLE_DOUBLE

public static final Duplication.WithFlip DOUBLE_DOUBLE

A flip instruction that flips a double-sized element over another double-size element.

Field Detail

opcode

private final int opcode

The opcode to apply.

stackSize

private final StackSize stackSize

The size that is added to the operand stack.

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.
