Class AdapterFactory

java.lang.Object
  |
  +--fr.umlv.jmmf.adapter.AdapterFactory

public class AdapterFactory

extends java.lang.Object

a factory for a generated specialized adapter. There 3 parts in the factory interface :

• the methods setKeepAdapteeInterfaces, isKeepAdapteeInterfaces, and addInterfaces, this methods permit to describe the interface of a generated adapter.
• the methods addMultiMethod provide implementation methods of a generated adapter.
• the method create, create a specilized adapter for an object.

All adapter created by this factory implements the Adapter interface.

void	addMultiMethods(java.lang.Object target, MultiMethod[] mms, int invocationOption)
java.lang.Object	create(java.lang.Object adaptee) generate a specialized adapter.
protected java.lang.Class[]	getInterfaces(java.lang.Class adapteeClass)
boolean	isKeepAdapteeInterfaces() get the keepAdapteeInterfaces flag. if this flag is true, the interfaces of the adaptee is implemented by the generic adapter.
void	setKeepAdapteeInterfaces(boolean keepAdapteeInterfaces) set the keepAdapteeInterfaces flag. if this flag is true, the interfaces of the adaptee is implemented by the generic adapter.

Constructor Detail

AdapterFactory

public AdapterFactory()

construct a default adapter factory.

AdapterFactory

public AdapterFactory(java.lang.Class type)

construct an adapter factory where all generated adapters implements the class take as argument.

Parameters:

type - must be an interface.

Method Detail

setKeepAdapteeInterfaces

public void setKeepAdapteeInterfaces(boolean keepAdapteeInterfaces)

set the keepAdapteeInterfaces flag. if this flag is true, the interfaces of the adaptee is implemented by the generic adapter.

Parameters:

keepAdapteeInterfaces - the new value of the flag.

isKeepAdapteeInterfaces

public boolean isKeepAdapteeInterfaces()

get the keepAdapteeInterfaces flag. if this flag is true, the interfaces of the adaptee is implemented by the generic adapter.

Returns:

the value of the keepAdapteeInterfaces flag.

addInterface

public void addInterface(java.lang.Class interfaze)

add an interface for all generated adapter.

Parameters:

interfaze - interface that all generated adapter must implements.

addInterface

public void addInterface(java.lang.Class adapteeClass,
                         java.lang.Class interfaze)

add an interface for all adapter for which the adaptee implements adapteeClass.

Parameters:

adapteeClass - class of one adaptee.

interfaze - all generated adapter that wrapped an adaptee that implements the adapteeClass must implements this interface.

addMultiMethod
