Class OsgiServiceLifecycleListenerAdapter

java.lang.Object

org.eclipse.gemini.blueprint.config.internal.adapter.OsgiServiceLifecycleListenerAdapter

All Implemented Interfaces:

OsgiServiceLifecycleListener, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.InitializingBean

public class OsgiServiceLifecycleListenerAdapter
extends java.lang.Object
implements OsgiServiceLifecycleListener, org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.BeanFactoryAware

OsgiServiceLifecycleListener wrapper for custom beans, useful when custom methods are being used.

Note: To support cyclic injection, this adapter does dependency lookup for the actual listener.

bind

public void bind(java.lang.Object service,
                 java.util.Map properties)
          throws java.lang.Exception

Description copied from interface: OsgiServiceLifecycleListener

Called when a service is being binded inside the proxy (be it single or multi value). The service properties are made available as a Map which can be safely cast to a Dictionary if needed.

Specified by:

Parameters:

service - the OSGi service instance

properties - the service properties

Throws:

java.lang.Exception - custom exception that is logged but not propagated to other listeners

Called when a service is being unbinded inside the proxy (be it single or multi value). The service properties are made available as a Map which can be safely cast to a Dictionary if needed.

Specified by:

unbind in interface OsgiServiceLifecycleListener

Parameters:

service - the OSGi service instance

properties - the service properties

Throws:

java.lang.Exception - custom exception that is logged but not propagated to other listeners

setBindMethod

public void setBindMethod(java.lang.String bindMethod)

Parameters:
