Enum Constant Detail

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.

Method Detail

values

public static Removal[] 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 (Removal c : Removal.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Removal 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

pop

public static StackManipulation pop(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()

Description copied from interface: StackManipulation

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(MethodVisitor methodVisitor,
                                    Implementation.Context implementationContext)

Description copied from interface: StackManipulation

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.

toString

public String toString()

Overrides:

toString in class Enum<Removal>
