The pure class interface. 
public abstract class OperationFactoryFilter
  extends OperationFactory
An instance of this class delegates all methods to another OperationFactory. It is intended to be used as a base class for classes that prevent certain kinds of Operations from being created.

Constructors

O OperationFactoryFilter
public OperationFactoryFilter(OperationFactory factory);
Creates an OperationFactory that delegates all requests to the given OperationFactory, except the ones overridden by subclasses.

Parameters:
factory - the OperationFactory it delegates to.

Methods

O getObject
public final Object getObject();
Should return the Object this OperationFactory creates Operations for. For static Operations, it will be the target class.

Returns:
the target Object for this class.
Overrides:
getObject in class OperationFactory

O nop

public Operation nop()
  throws IllegalAccessException;
Asks the OperationFactoryFilter specified in the constructor to create a do-nothing Operation.

Returns:
the new Operation.
Throws:
IllegalAccessException -propagated.
Overrides:
nop in class OperationFactory

O invoke

public Operation invoke(Method method,
                        Object[] arguments,
                        Operation operation)
  throws IllegalArgumentException, IllegalAccessException;
Asks the OperationFactoryFilter specified in the constructor to create a Method invocation Operation.

Parameters:
method - the Method to be invoked.
arguments - the argument list to be passed to the Method.
operation - an Operation that should be replaced. If it is null, a non-replacement Operation is created.
Returns:
the new Operation.
Throws:
IllegalArgumentException -propagated.
IllegalAccessException -propagated.
Overrides:
invoke in class OperationFactory

O construct

public Operation construct(Constructor constructor,
                           Object[] arguments,
                           Operation operation)
  throws IllegalArgumentException, IllegalAccessException;
Asks the OperationFactoryFilter specified in the constructor to create a Constructor invocation Operation.

Parameters:
constructor - the Constructor to be invoked.
arguments - the argument list to be passed to the Constructor.
operation - an Operation that should be replaced. If it is null, a non-replacement Operation is created.
Returns:
the new Operation.
Throws:
IllegalArgumentException -propagated.
IllegalAccessException -propagated.
Overrides:
construct in class OperationFactory

O monitorEnter

public Operation monitorEnter(Operation operation)
  throws IllegalArgumentException, IllegalAccessException;
Asks the OperationFactoryFilter specified in the constructor to create a start-of-synchronization Operation.

Parameters:
operation - an Operation that should be replaced. If it is null, a non-replacement Operation is created.
Returns:
the new Operation.
Throws:
IllegalArgumentException -propagated.
IllegalAccessException -propagated.
Overrides:
monitorEnter in class OperationFactory

O monitorExit

public Operation monitorExit(Operation operation)
  throws IllegalArgumentException, IllegalAccessException;
Asks the OperationFactoryFilter specified in the constructor to create an end-of-synchronization Operation.

Parameters:
operation - an Operation that should be replaced. If it is null, a non-replacement Operation is created.
Returns:
the new Operation.
Throws:
IllegalArgumentException -propagated.
IllegalAccessException -propagated.
Overrides:
monitorExit in class OperationFactory

O read

public Operation read(Field field,
                      Operation operation)
  throws IllegalArgumentException, IllegalAccessException;
Asks the OperationFactoryFilter specified in the constructor to create a Field read Operation.

Parameters:
field - the Field whose value is to be obtained.
operation - an Operation that should be replaced. If it is null, a non-replacement Operation is created.
Returns:
the new Operation.
Throws:
IllegalArgumentException -propagated.
IllegalAccessException -propagated.
Overrides:
read in class OperationFactory

O write

public Operation write(Field field,
                       Object value,
                       Operation operation)
  throws IllegalArgumentException, IllegalAccessException;
Asks the OperationFactoryFilter specified in the constructor to create a Field write Operation.

Parameters:
field - the Field whose value is to be changed.
value - the value to be stored in the Field.
