Class OptimizedCompositeBindingMixin

java.lang.Object
  org.objectweb.fractal.julia.control.binding.OptimizedCompositeBindingMixin

All Implemented Interfaces:

BindingController

public abstract class OptimizedCompositeBindingMixin

extends Object

implements BindingController

Provides optimized ComponentInterface management to a BindingController. This mixin uses shortcut links between component interfaces where possible, i.e. when some interfaces do not have associated interceptors.

Requirements

• the component to which this controller object belongs must provide the Component and ContentController interfaces.
• TODO.

The weaveableC field required by this mixin. This field is supposed to reference the Component interface of the component to which this controller object belongs.

_this_weaveableCC

public ContentController _this_weaveableCC

The weaveableCC field required by this mixin. This field is supposed to reference the ContentController interface of the component to which this controller object belongs.

Method Detail

bindFc

public void bindFc(InterfaceType clientItfType,

                   IllegalLifeCycleException

Sets the shortcuts for the given binding and then calls the overriden method.

Parameters:

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

serverItf - a server interface.

Throws:

NoSuchInterfaceException - if there is no such client interface.

IllegalBindingException - if the binding cannot be created.

IllegalLifeCycleException - if this component has a LifeCycleController interface, but it is not in an appropriate state to perform this operation.

unbindFc

public void unbindFc(InterfaceType clientItfType,
                     String clientItfName)
              throws NoSuchInterfaceException,

                     IllegalLifeCycleException

Updates the shortcuts for the given binding and then calls the overriden method.

Parameters:

clientItfType - the type of the clientItfName interface.

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.

setFcShortcuts

public void setFcShortcuts(InterfaceType clientItfType,

                    throws NoSuchInterfaceException,
                           IllegalBindingException

Creates the given binding and updates the shortcuts links accordingly.

Parameters:

clientItfType - the type of the 'clientItfName' interface.

clientItfName - a client interface name.

serverItf - the server interface to which the client interface must be bound, or null if it must be unbound.

Throws:

NoSuchInterfaceException - if there is no client interface whose name is equal to 'clientItfName'.

IllegalBindingException - if a problem occurs.

setFcClientShortcuts

public void setFcClientShortcuts(Interface clientItf,
