Class ThreadPolicyValue

public class ThreadPolicyValue extends Object implements Serializable, IDLEntity

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 {@link Servant#_object_id()} and {@link 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
static ThreadPolicyValue	ORB_CTRL_MODEL An instance of ThreadPolicyValue, initialized to ORB_CTRL_MODEL.
static ThreadPolicyValue	SINGLE_THREAD_MODEL An instance of ThreadPolicyValue, initialized to SINGLE_THREAD_MODEL.
static int	_ORB_CTRL_MODEL The possible value of this enumeration (ORB_CTRL_MODEL).
static int	_SINGLE_THREAD_MODEL The possible value of this enumeration (SINGLE_THREAD_MODEL).

Constructor Summary
protected	ThreadPolicyValue(int a_value) Normally, no new instances are required, so the constructor is protected.

Method Summary
static ThreadPolicyValue	from_int(int code) Returns the ThreadPolicyValue, matching the given integer constant.
String	toString() Returns a short string representation.
int	value() Returns the integer code of the enumeration value.
