Constructor Detail

ClassConstant

private ClassConstant(java.lang.Class<?> type)

Creates a new class constant for a primitive type.

Parameters:

type - The primitive type to represent.

Method Detail

values

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

Returns:

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

valueOf

public static ClassConstant 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

of

public static StackManipulation of(TypeDescription typeDescription)

Returns a stack manipulation that loads a Class type onto the operand stack which represents the given type.

Parameters:

typeDescription - The type to load onto the operand stack.

Returns:

The corresponding stack manipulation.

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.
