Method Detail

getDescriptor

public Descriptor getDescriptor()

eval

public Transportable eval(Transportable doc)
                   throws ServiceException
Main method called by the Vinci Service Layer. All requests coming in from clients go through this method. Each request comes in as a VinciFrame and is expected to contain a valid VINCI:COMMAND. Currently, two such operations are supported: 1) Annotate - triggers document analysis 2) GetData - triggers return of the AE meta data ( descriptor)

Specified by:
eval in interface VinciServable
Specified by:
eval in class VinciServableAdapter
Parameters:
{@link - org.apache.vinci.transport.Transportable} - a VinciFrame containing client request
Returns:
Transportable - a VinciFrame containg result of performing the service
Throws:
ServiceException - thrown when there is an application level error that should result in the client receiving the same ServiceException on the other end.

start

protected void start()
Starts this service and associates a ShutdownHook to handle gracefull shutdown.


stop

public void stop()
Terminate this service


main

public static void main(java.lang.String[] args)

makeTransportable

public Transportable makeTransportable()
Description copied from interface: TransportableFactory
Creates a new (empty) document of the desired type.

Specified by:
makeTransportable in interface TransportableFactory
Overrides:
makeTransportable in class VinciServableAdapter
Returns:
The new document.
