Method Details

apply

public double apply(int[] relevant,

getUniqueName

public String getUniqueName()

Description copied from interface: RelevancyFunction

Return a name which identifies this function in terms of its parameters. This is a temporary work-around until the graphite uniqueness semantics are removed and label set uniqueness works.

Returns:

A string which can be used to identify if the metric exists yet.
