public interface InterceptorManager

InterceptorManager interface. This interface is responsible for handling the registration, unregistration and invocation of the interceptors.

Method Summary

List	getInterceptors(InterceptionPoint ip) Returns the list of interceptors available at the given position.
Map	getInterceptorsAndIndice(InterceptionPoint ip) Returns the list of interceptors and their indices available at the given position.
void	register(Interceptor interceptor, InterceptionPoint ip, int index) Registers an interceptor at a given index and position.
void	register(Interceptor interceptor, InterceptionPoint ip, int index, boolean replacementAllowed) Registers an interceptor at a given index and position.
void	registerListener(InterceptorManagerListener listener) Register a listener.
void	unregister(Interceptor interceptor, InterceptionPoint ip) Unregister an interceptor.
void	unregister(int index, InterceptionPoint ip) Unregister an interceptor.
void	unregisterListener(InterceptorManagerListener listener) Unregister a listener.
void	update() Updates the current interceptors with any changes that have been made since the last call to update().

Method Detail

getInterceptors

public List getInterceptors(InterceptionPoint ip)

Returns the list of interceptors available at the given position.

Parameters:

ip - The interception point to get the interceptors

Returns:

The interceptors found at the given position

getInterceptorsAndIndice

public Map getInterceptorsAndIndice(InterceptionPoint ip)

Returns the list of interceptors and their indices available at the given position.

Parameters:

ip - The interception point to get the interceptors

Returns:

The interceptors found at the given position

register

public void register(Interceptor interceptor,
                     InterceptionPoint ip,
                     int index)

Registers an interceptor at a given index and position. The index indicates where the interceptor will be located in the flow of interceptors for a given position. The index can be any positive (MAX_INT) or negative integer (MIN_INT): the interceptors will be executed from the lowest to the largest index. Note: the method update() must be called for this action to take effect.

Parameters:

interceptor - The interceptor to register

ip - The interception point of the request at which the interceptor should be invoked

index - The index where the interceptor will be located in the flow

register

public void register(Interceptor interceptor,
                     InterceptionPoint ip,
                     int index,
                     boolean replacementAllowed)

Registers an interceptor at a given index and position. The index indicates where the interceptor will be located in the flow of interceptors for a given position. The index can be any positive (MAX_INT) or negative integer (MIN_INT): the interceptors will be executed from the lowest to the largest index.

Parameters:

interceptor - The interceptor to register

ip - interceptor The interceptor to register

index - The index where the interceptor will be located in the flow

replacementAllowed - If true, it means the interceptor can replace existed one with same index

registerListener

public void registerListener(InterceptorManagerListener listener)

Register a listener.

Parameters:

listener - listener

unregister

public void unregister(Interceptor interceptor,
                       InterceptionPoint ip)

Unregister an interceptor. Note: the method update() must be called for this action to take effect.

Parameters:

interceptor - The interceptor to unregister

ip - The interception point of the request at which the interceptor should be invoked

unregister

public void unregister(int index,
                       InterceptionPoint ip)

Unregister an interceptor. Note: the method update() must be called for this action to take effect.

Parameters:

index - The index of the interceptor

ip - The interception point of the request at which the interceptor should be invoked

unregisterListener

public void unregisterListener(InterceptorManagerListener listener)

Unregister a listener.

Parameters:

listener - listener

update

public void update()

Updates the current interceptors with any changes that have been made since the last call to update().
