Method Summary

java.lang.String	getServiceExtensionPointId() Return the full id of the service extension point for which interceptors are being fabricated.
java.lang.Class	getServiceInterface() Returns the interface for the service; the same as ServicePoint.getServiceInterface().
org.apache.commons.logging.Log	getServiceLog() Returns the Log instance that should be used to log any information about the service, or the construction of the service.
Module	getServiceModule() Returns the module which contains the service extension point.
java.lang.Object	peek() Returns the current top object on the stack.
void	push(java.lang.Object interceptor) Pushes a new instance onto the stack.

Method Detail

getServiceExtensionPointId

public java.lang.String getServiceExtensionPointId()

Return the full id of the service extension point for which interceptors are being fabricated.

getServiceModule

public Module getServiceModule()

Returns the module which contains the service extension point.

getServiceInterface

public java.lang.Class getServiceInterface()

Returns the interface for the service; the same as ServicePoint.getServiceInterface().

peek

public java.lang.Object peek()

Returns the current top object on the stack.

push

public void push(java.lang.Object interceptor)

Pushes a new instance onto the stack. The new instance should be a wrapper around peek(), and should implement the service extension point's interface.

The stack checks that the interceptor is not null, and that the interceptor implements the service interface.

getServiceLog

public org.apache.commons.logging.Log getServiceLog()

Returns the Log instance that should be used to log any information about the service, or the construction of the service.
