init(AdaptorContext context)
Initialize adaptor with the current context.

Provides the opportunity for the Adaptor to create new configuration values
or override default values.

AbstractAdaptorConfig.addKey(java.lang.String, java.lang.String) should likely be
called. The user's configuration will override any values set in this way.
This method is called by AbstractAdaptor.main(com.google.enterprise.adaptor.Adaptor, java.lang.String[]) before Adaptor.init(com.google.enterprise.adaptor.AdaptorContext)
is called.
This implementation does nothing.
initConfig in interface AdaptorinitConfig in class AbstractAdaptorpublic void init(AdaptorContext context) throws Exception
AbstractAdaptorcontext
points to other useful objects that can be used at any time. For example,
methods on DocIdPusher provided via AdaptorContext.getDocIdPusher() are allowed to be called whenever the
Adaptor wishes. This allows doing event-based incremental pushes at any
time.
The method is called at the end of GsaCommunicationHandler.start(java.lang.Runnable).
If you experience a fatal error during initialization, feel free to
throw an Exception to cancel the startup process.
This implementation does nothing.
