Method Detail

communicationChannelBroken

public void communicationChannelBroken()

Description copied from class: ServiceCallee

This abstract method is called for each member of the bus when the bus is being stopped.

Specified by:

communicationChannelBroken in class ServiceCallee

handleCall

public ServiceResponse handleCall(ServiceCall call)

Handles the incoming ServiceCall and check if it fits to methods declared by wrapped object. If so, it invoke such method with reflection and create proper ServiceResponse It is crucial to remember that Output in ServiceResponse has to be either List or RDF object because TypeMapper.asLiteral does not support other types. If output is an Array it is automatically converted into a List.

Specified by:

handleCall in class ServiceCallee

Parameters:

call - the call that needs to be serviced.

Returns:

the result of the call execution.

getProfiles

public ServiceProfile[] getProfiles()
