Method Detail

clone

public DecayingKeyspaceAverage clone()

Description copied from interface: RunningAverage

Copy the RunningAverage (create a snapshot). Deep copy, the new RA won't change when the first one does. Will synchronize on the original during the copy process.

Specified by:

clone in interface RunningAverage

Overrides:

clone in class java.lang.Object

currentValue

public double currentValue()

Specified by:

currentValue in interface RunningAverage

Returns:

report

public void report(double d)

Specified by:

report in interface RunningAverage

Parameters:

d -

valueIfReported

public double valueIfReported(double d)

Description copied from interface: RunningAverage

Get what currentValue() would be if we reported some given value

Specified by:

valueIfReported in interface RunningAverage

Parameters:

d - the value to mimic reporting

Returns:

the output of currentValue() if we were to report r

countReports

public long countReports()

Specified by:

countReports in interface RunningAverage

Returns:

the total number of reports on this RunningAverage so far. Used for weighted averages, confidence/newbieness estimation etc.

report

public void report(long d)

Specified by:

report in interface RunningAverage

Parameters:

d -

changeMaxReports

public void changeMaxReports(int maxReports)

Parameters:

maxReports -

exportFieldSet
