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

make

public List<MethodCall.ArgumentLoader> make(Implementation.Target implementationTarget,
                                            TypeDescription instrumentedType,
                                            MethodDescription instrumentedMethod,
                                            MethodDescription invokedMethod)

Creates any number of argument loaders for an instrumentation.

Specified by:

make in interface MethodCall.ArgumentLoader.Factory

Parameters:

implementationTarget - The implementation target.

instrumentedType - The instrumented type.

instrumentedMethod - The instrumented method.

invokedMethod - The invoked method.

Returns:

Any number of argument loaders to supply for the method call.

resolve

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

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

Specified by:

resolve 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.

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.
