Class ServiceContext

java.lang.Object

com.sun.corba.se.spi.servicecontext.ServiceContext

Direct Known Subclasses:

UEInfoServiceContext, UnknownServiceContext

public abstract class ServiceContext
extends Object

Base class for all ServiceContext classes. There is a derived ServiceContext class for each service context that the ORB supports. Each subclass encapsulates the representation of the service context and provides any needed methods for manipulating the service context. Each subclass must provide the following members:

a public static final int SERVICE_CONTEXT_ID that gives the OMG (or other) defined id for the service context. This is needed for the registration mechanism defined in ServiceContexts. OMG defined service context ids are taken from section 13.6.7 of ptc/98-12-04.
• a public constructor that takes an InputStream as its argument.
• Appropriate definitions of getId() and writeData(). getId() must return SERVICE_CONTEXT_ID.

The subclass can be constructed either directly from the service context representation, or by reading the representation from an input stream. These cases are needed when the service context is created and written to the request or reply, and when the service context is read from the received request or reply.
