Examples of org.rioproject.impl.watch.WatchDataSourceImpl

org.rioproject.impl.watch.WatchDataSourceImpl

The WatchDataSourceImpl provides support for the WatchDataSource interface. The WatchDataSourceImpl supports the following configuration entries; where each configuration entry name is associated with the component name org.rioproject.watch

watchDataSourceExporter

Type:	Exporter
Default:	A new `BasicJeriExporter` with a `TcpServerEndpoint` created on a random port, a `BasicILFactory`, distributed garbage collection turned off, keep alive on.
Description:	The Exporter used to export the WatchDataSourceImpl server. A new exporter is obtained every time a WatchDataSourceImpl needs to export itself.

collectionSize

Type:
int

Default:
1000

Description:
The size of the WatchDataSource history collection.
