public class: ThreadPolicyValue [javadoc | source]

java.lang.Object
   org.omg.PortableServer.ThreadPolicyValue

All Implemented Interfaces:
IDLEntity, Serializable

Defines the possible values for the POA thread policy. This enumeration can obtain the following values:

ORB_CTRL_MODEL Each object in POA has a separate serving thread and a separate server socket, listening on the objects individual port. Additionally, when the request is accepted, it is also served in a separate thread, so several requests to the same object can be processed in parallel. The servant can always get the Id and POA of the object it is currently serving by invoking Servant#_object_id() and Servant#_poa . These two methods use thread to data map and must work correctly even then the servant code is executed in several parallel threads.
SINGLE_THREAD_MODEL All objects in POA share the same server socket and are served in the same thread. This model is applicable when the number of objects is greater than the number of threads and (or) ports, supported by the system.

OMG also defines a MAIN_THREAD_MODEL, currently not supported by the java API.

Field Summary
public static final int	_ORB_CTRL_MODEL	The possible value of this enumeration (ORB_CTRL_MODEL).
public static final ThreadPolicyValue	ORB_CTRL_MODEL	An instance of ThreadPolicyValue, initialized to ORB_CTRL_MODEL.
public static final int	_SINGLE_THREAD_MODEL	The possible value of this enumeration (SINGLE_THREAD_MODEL).
public static final ThreadPolicyValue	SINGLE_THREAD_MODEL	An instance of ThreadPolicyValue, initialized to SINGLE_THREAD_MODEL.

Constructor:
protected ThreadPolicyValue(int a_value) { _value = a_value; } Normally, no new instances are required, so the constructor is protected.
