Class UnsafeHackConcreteClassImposteriser

java.lang.Object
  org.jmock.lib.nonstd.UnsafeHackConcreteClassImposteriser

All Implemented Interfaces:

Imposteriser

public class UnsafeHackConcreteClassImposteriser
extends Object
implements Imposteriser

This class lets you imposterise concrete classes with CGLIB without calling the constructors of the mocked class. However, it uses undocumented, internal features of Sun's JVM. It will not work on JVMs from other vendors. Sun may remove the undocumented feature this class relies upon in any future versions. You have been warned!

Method Detail

canImposterise

public boolean canImposterise(Class<?> type)

Description copied from interface: Imposteriser

Reports if the Imposteriser is able to imposterise a given type.

Specified by:

canImposterise in interface Imposteriser

Parameters:

type - The type in question.

Returns:

True if this imposteriser can imposterise type, false otherwise.

imposterise

public <T> T imposterise(Invokable mockObject,
                         Class<T> mockedType,
                         Class<?>... ancilliaryTypes)

Description copied from interface: Imposteriser

Creates an imposter for a given type that forwards Invocations to an Invokable object.

Specified by:

imposterise in interface Imposteriser

Type Parameters:

T - The static type of the imposter that is created.

Parameters:

mockObject - The object that is to receive invocations forwarded from the imposter.

mockedType - The class representing the static type of the imposter.

ancilliaryTypes - Other types for the imposter. It must be possible to dynamically cast the imposter to these types. These types must all be interfaces because Java only allows single inheritance of classes.

Returns:

A new imposter. The imposter must implement the mockedType and all the ancialliaryTypes.
