Enum Constant Detail

ZERO

public static final FloatConstant ZERO

A float constant of value 0.0f.

ONE

public static final FloatConstant ONE

A float constant of value 1.0f.

TWO

public static final FloatConstant TWO

A float constant of value 2.0f.

Method Detail

values

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

Returns:

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

valueOf

public static FloatConstant 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

forValue

public static StackManipulation forValue(float value)

Creates a stack manipulation for loading a float value onto the operand stack.

This is achieved either by invoking a specific opcode, if any, or by creating a constant pool entry.

Parameters:

value - The float value to load onto the stack.

Returns:

A stack manipulation for loading the given float value.

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.
