Enum Constant Detail

INSTANCE

public static final MethodCall.ArgumentLoader.ForNullConstant INSTANCE

The singleton instance.

Method Detail

values

public static MethodCall.ArgumentLoader.ForNullConstant[] 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 (MethodCall.ArgumentLoader.ForNullConstant c : MethodCall.ArgumentLoader.ForNullConstant.values())
    System.out.println(c);

Returns:

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

valueOf

public static MethodCall.ArgumentLoader.ForNullConstant 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

prepare

public InstrumentedType prepare(InstrumentedType instrumentedType)

Prepares a given instrumented type.

Specified by:

prepare in interface InstrumentedType.Prepareable

Parameters:

instrumentedType - The instrumented type in its current form.

Returns:

The prepared instrumented type.

make

public MethodCall.ArgumentLoader.ArgumentProvider make(Implementation.Target implementationTarget)

Creates an argument provider for the supplied implementation target.

Specified by:

make in interface MethodCall.ArgumentLoader.Factory

Parameters:

implementationTarget - The implementation target to use.

Returns:

An appropriate argument provider.

resolve

public List<MethodCall.ArgumentLoader> resolve(MethodDescription instrumentedMethod,
                                               MethodDescription invokedMethod)

Resolves this provider to an argument loader for each provided argument.

Specified by:

resolve in interface MethodCall.ArgumentLoader.ArgumentProvider

Parameters:

instrumentedMethod - The instrumented method.

invokedMethod - The invoked method.

Returns:

A list of provided argument loaders.

toStackManipulation

public StackManipulation toStackManipulation(ParameterDescription target,
                                             Assigner assigner,
                                             Assigner.Typing typing)

Loads the argument that is represented by this instance onto the operand stack.

Specified by:

toStackManipulation in interface MethodCall.ArgumentLoader

Parameters:

target - The target parameter.

assigner - The assigner to be used.

typing - Indicates if dynamic type castings should be attempted for incompatible assignments.

Returns:

The stack manipulation that loads the represented argument onto the stack.
