Class BasicBindingControllerMixin

java.lang.Object
  extended byorg.objectweb.fractal.julia.control.binding.BasicBindingControllerMixin
All Implemented Interfaces:
BindingController

public abstract class BasicBindingControllerMixin
extends Object
implements BindingController

Provides a basic implementation of the BindingController interface. This mixin uses a map to store the bindings of the component.

Requirements


Field Summary
 Map fcBindings
          The bindings of the component to which this controller object belongs.
 
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.
 Object lookupFc(String clientItfName)
          Returns the interface to which the given client interface is bound.
 void unbindFc(String clientItfName)
          Unbinds the given client interface.

Field Detail

fcBindings

public Map fcBindings
The bindings of the component to which this controller object belongs. This map associates to each client interface name the server interface to which it is bound. If a client interface is not bound, its name is not associated to null, but to the fcBindings map itself. This way the listFc method returns the names of all the client interfaces of the component, and not only the names of the interfaces that are bound.

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)
                throws NoSuchInterfaceException
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.
Throws:
NoSuchInterfaceException - if the component to which this interface belongs does not have a client interface whose name is equal to the given name.

bindFc

public void bindFc(String clientItfName,
                   Object serverItf)
            throws NoSuchInterfaceException,
                   IllegalBindingException,
                   IllegalLifeCycleException
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.
Throws:
IllegalLifeCycleException - if this component has a LifeCycleController interface, but it is not in an appropriate state to perform this operation.
NoSuchInterfaceException - if there is no such client interface.
IllegalBindingException - if the binding cannot be created.

unbindFc

public void unbindFc(String clientItfName)
              throws NoSuchInterfaceException,
                     IllegalBindingException,
                     IllegalLifeCycleException
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.
Throws:
NoSuchInterfaceException - if there is no such client interface.
IllegalBindingException - if the binding cannot be removed.
IllegalLifeCycleException - if this component has a LifeCycleController interface, but it is not in an appropriate state to perform this operation.
