static String	STORAGE_BINDING A mandatory client interface bound to a storage.

Constructor Summary

BasicRepository()

Method Summary

void	bindFc(String clientItfName, Object serverItf) Binds the client interface whose name is given to a server interface.
String[]	listFc() Returns the names of the client interfaces of the component to which this interface belongs.
Component	loadComponent(String name) Loads a component (and all its sub components) from this repository.
Object	lookupFc(String clientItfName) Returns the interface to which the given client interface is bound.
String	storeComponent(Component component) Stores a component (and all its sub components) into this repository.
void	unbindFc(String clientItfName) Unbinds the given client interface.

Method Detail

listFc

public String[] listFc()

Description copied from interface: BindingController

Returns the names of the client interfaces of the component to which this interface belongs.

Specified by:

listFc in interface BindingController

Returns:

the names of the client interfaces of the component to which this interface belongs.

lookupFc

public Object lookupFc(String clientItfName)

Description copied from interface: BindingController

Returns the interface to which the given client interface is bound. More precisely, returns the server interface to which the client interface whose name is given is bound. This server interface is necessarily in the same address space as the client interface (see bindFc).

Specified by:

lookupFc in interface BindingController

Parameters:

clientItfName - the name of a client interface of the component to which this interface belongs.

Returns:

the server interface to which the given interface is bound, or null if it is not bound.

bindFc

public void bindFc(String clientItfName,
                   Object serverItf)

Description copied from interface: BindingController

Binds the client interface whose name is given to a server interface. More precisely, binds the client interface of the component to which this interface belongs, and whose name is equal to the given name, to the given server interface. The given server interface must be in the same address space as the client interface.

Specified by:

bindFc in interface BindingController

Parameters:

clientItfName - the name of a client interface of the component to which this interface belongs.

serverItf - a server interface.

unbindFc

public void unbindFc(String clientItfName)

Description copied from interface: BindingController

Unbinds the given client interface. More precisely, unbinds the client interface of the component to which this interface belongs, and whose name is equal to the given name.

Specified by:

unbindFc in interface BindingController

Parameters:

clientItfName - the name of a client interface of the component to which this interface belongs.

loadComponent

public Component loadComponent(String name)
                        throws Exception

Description copied from interface: Repository

Loads a component (and all its sub components) from this repository.

Specified by:

loadComponent in interface Repository

Parameters:

name - the name of the component to be loaded.

Returns:

the loaded component.

Throws:

Exception - if the component cannot loaded.

storeComponent

public String storeComponent(Component component)
                      throws Exception

Description copied from interface: Repository

Stores a component (and all its sub components) into this repository.

Specified by:

storeComponent in interface Repository

Parameters:

component - the component to be stored.

Returns:

the name of the component that has been stored.

Throws:

Exception - if the component cannot be stored.
