Class AbstractMetricFunction<N>

java.lang.Object
  com.tibco.rta.runtime.metric.AbstractMetricFunction<N>

Type Parameters:

N - The data type of the metric computation.

All Implemented Interfaces:

MetricFunction<N>

Direct Known Subclasses:

MultiValueMetricFunction, SingleValueMetricFunction

public abstract class AbstractMetricFunction<N>
extends java.lang.Object
implements MetricFunction<N>

An abstract metric function. Metric function implementations will indirectly extend this as a result of extending either SingleValue of MultiValueMetricFunction.
