Interface AggregationValue

All Known Implementing Classes:
AvgValue, CountValue, Distribution, LinearDistribution, LogDistribution, MaxValue, MinValue, StddevValue, SumValue

public interface AggregationValue

A value accumulated by an aggregating DTrace action such as count() or sum(). Each AggregationValue is associated with a Tuple in an AggregationRecord. In other words it is a value in a key-value pair (each pair representing an entry in a DTrace aggregation).

This value may be a single number or consist of multiple numbers, such as a value distribution. In the latter case, it still has a single, composite value useful for display and/or comparison.
