public java.lang.String getServiceExtensionPointId()

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

public org.apache.hivemind.internal.Module getServiceModule()

Returns the module which contains the service extension point.

public java.lang.Class getServiceInterface()

Returns the interface for the service; the same as ServicePoint.getServiceInterface()>ServicePoint.getServiceInterface() 55 .

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() 55 , and should implement the service extension point's interface.
