All Implemented Interfaces:

InvocationCodes, TimeBaseCodes, InvocationProvider

public class TimeBaseProvider
extends Object
implements InvocationProvider, TimeBaseCodes

Provides the server-side of the time base services. The time base services provide a means by which delta times can be sent over the network which are expanded based on a shared base time into full time stamps.

Field Summary

protected static InvocationManager	_invmgr The invocation manager with which we interoperate.
protected static RootDObjectManager	_omgr The distributed object manager with which we interoperate.
protected static HashMap<String,TimeBaseObject>	_timeBases Used to keep track of our time base objects.

Constructor Summary

TimeBaseProvider()

Method Summary

static TimeBaseObject	createTimeBase(String timeBase) Creates a time base object which can subsequently be fetched by the client and used to send delta times.
static TimeBaseObject	getTimeBase(String timeBase) Returns the named timebase object, or null if no time base object has been created with that name.
void	getTimeOid(ClientObject source, String timeBase, TimeBaseService.GotTimeBaseListener listener) Processes a request from a client to fetch the oid of the specified time object.
static void	init(InvocationManager invmgr, RootDObjectManager omgr) Registers the time provider with the appropriate managers.
