com.opengamma.engine.view.client.ViewClient
Represents a managed client of a specific view process in the context of a particular user. This is the unit of external interaction for accessing computation results.
The client begins detached from any particular view process. In order to receive results, it must be attached to a view process. This creates demand for the process to execute, ensuring that it remains executing while the client is attached.
If the application requires asynchronous updates, it must set a result listener. This receives notifications of events from the view process. The result mode for this client may be controlled using {@link #setResultMode(ViewResultMode)}; this allows unwanted types of result to be filtered out, potentially avoiding the overhead of unnecessary serialisation.
The application may poll for the latest full result by calling {@link #getLatestResult()}. Listeners can be set or changed even when the client is detached from a view process; this allows the necessary listeners to be in place before results commence.
The per-client flow of results is controlled through {@link #pause()} and {@link #resume()}. By default, results will flow immediately, but the client may be paused before attaching it to a view process.
When results are paused, they are incrementally batched to be delivered as a single, collapsed result when they are resumed. This result is specific to the individual client that has been paused.
Use {@link #setUpdatePeriod(long)} to throttle the frequency of updates exposed through this client.
Always call {@link #shutdown()} from any state to allow resources associated with the managed view to be releasedwhen the client is no longer required. Without this, the view process may continue executing indefinitely.
