public final class UtilizationFilter extends org.palladiosimulator.edp2.datastream.filter.AbstractAdapter implements org.palladiosimulator.edp2.datastream.filter.IFilter, IPersistable, IPersistableElement
This class is a moving average implementation that calculates the utilization of an active resource based on a set of (point in time, state of active resource) tuple measurements, or,
in case of a multi-core resource, based on a set of (point in time, 'overall' utilization of active resource) tuple measurements.
That is, when being applied to an IDataSource that provides measurements adhering to this metric, this filter outputs a set of subsequent (point in time, utilization) tuples. This result set can be obtained by calling the getDataStream() method.
