use of org.eclipse.tracecompass.statesystem.core.exceptions.TimeRangeException in project tracecompass by tracecompass.

/**
 * Return the state history of a given attribute, but with at most one
 * update per "resolution". This can be useful for populating views (where
 * it's useless to have more than one query per pixel, for example). A
 * progress monitor can be used to cancel the query before completion.

 * @param attributeQuark
 *            Which attribute this query is interested in
 * @param t1
 *            Start time of the range query
 * @param t2
 *            Target end time of the query. If t2 is greater than the end of
 *            the trace, we will return what we have up to the end of the
 *            history.
 * @param resolution
 *            The "step" of this query
 * @param monitor
 *            A progress monitor. If the monitor is canceled during a query,
 *            we will return what has been found up to that point. You can
 *            use "null" if you do not want to use one.
 * @return The List of states that happened between t1 and t2
 * @throws TimeRangeException
 *             If t1 is invalid, if t2 {@literal <=} t1, or if the
 *             resolution isn't greater than zero.
 * @throws AttributeNotFoundException
 *             If the attribute doesn't exist
 * @throws StateSystemDisposedException
 *             If the query is sent after the state system has been disposed
