Class AutoRefreshManager

java.lang.Object

org.lsst.ccs.gconsole.plugins.trending.AutoRefreshManager

public final class AutoRefreshManager
extends Object

Handles automatic refreshing of trending plots. The class is thread-safe, all public methods can be called from any thread.

Auto-refreshing is started by calling start(), stopped by calling stop(). updatePreferences() should be called if relevant preferences change.

A singleton of this class maintains an executor for auto-refreshing, and runs a task on the Agent's scheduler to find plots that require refreshing. For these plots, LsstTrendingPlugin.refresh(trends) is called on the executor thread.
