Field Summary

protected org.apache.commons.logging.Log

_log This log is created from the log's service id, which is the appropriate place to log any messages related to creating (or managing) the service implementation, proxy, etc.

Constructor Summary

AbstractServiceModelImpl(ConstructableServicePoint servicePoint)

Method Summary

protected java.lang.Object	addInterceptors(java.lang.Object core)
protected java.lang.Object	constructBridgeProxy(java.lang.Object service) Need to bridge from the service interface to the actual type.
protected java.lang.Object	constructCoreServiceImplementation() Constructs the core service implementation (by invoking the ImplementationConstructor), and checks that the result is non-null and assignable to the service interface.
protected java.lang.Object	constructNewServiceImplementation() Constructs a new implementation of the service, starting with a core implementation, then adding any interceptors.
protected java.lang.Object	constructServiceImplementation() Constructs the service implementation; this is invoked from ServicePoint.getService(Class) (for singletons), or from the generated deferrable proxy (for most service models).
ConstructableServicePoint	getServicePoint()
protected void	registerWithShutdownCoordinator(java.lang.Object service) Invoked after creating a service implementation object; if the object implements RegistryShutdownListener, then the object is added as a listener.

Field Detail

_log

protected final org.apache.commons.logging.Log _log

This log is created from the log's service id, which is the appropriate place to log any messages related to creating (or managing) the service implementation, proxy, etc. Subclasses should make use of this Log as well.

Constructor Detail

AbstractServiceModelImpl

public AbstractServiceModelImpl(ConstructableServicePoint servicePoint)

Method Detail

addInterceptors

protected java.lang.Object addInterceptors(java.lang.Object core)

constructCoreServiceImplementation

protected java.lang.Object constructCoreServiceImplementation()

Constructs the core service implementation (by invoking the ImplementationConstructor), and checks that the result is non-null and assignable to the service interface.

constructServiceImplementation

protected java.lang.Object constructServiceImplementation()

Constructs the service implementation; this is invoked from ServicePoint.getService(Class) (for singletons), or from the generated deferrable proxy (for most service models). Primarily, invokes constructNewServiceImplementation() from within a block that checks for recursive builds.

constructNewServiceImplementation

protected java.lang.Object constructNewServiceImplementation()

Constructs a new implementation of the service, starting with a core implementation, then adding any interceptors.

getServicePoint

public ConstructableServicePoint getServicePoint()

constructBridgeProxy

protected java.lang.Object constructBridgeProxy(java.lang.Object service)

Need to bridge from the service interface to the actual type.

Since:

1.1

registerWithShutdownCoordinator

protected void registerWithShutdownCoordinator(java.lang.Object service)

Invoked after creating a service implementation object; if the object implements RegistryShutdownListener, then the object is added as a listener.

Parameters:

service - the service implementation

Since:

1.2
