accumulate

public Accumulator<NullSupportingData> accumulate(Quantity quantity)

Description copied from interface: Accumulator

Add the specified Quantity to the accumulated value. It is permissible to mix calls to accumulate with Quantity and CalculatedValue.

Specified by:

accumulate in interface Accumulator<NullSupportingData>

Parameters:

quantity - The Quantity to include in the accumulated value.

Returns:

This Accumulator.

accumulate

public Accumulator<NullSupportingData> accumulate(CalculatedValue<NullSupportingData> calculatedValue)

Description copied from interface: Accumulator

Add the specified CalculatedValue to the accumulated value. The CalculatedValue was produced by this Accumulator in a different context. For example, for a different time period or a different host. It is permissible to mix calls to accumulate with Quantity and CalculatedValue.

Specified by:

accumulate in interface Accumulator<NullSupportingData>

Parameters:

calculatedValue - The CalculatedValue to include in the accumulated value.

Returns:

This Accumulator.

calculate

public CalculatedValue<NullSupportingData> calculate(Map<Statistic,Calculator<?>> dependencies)

Description copied from interface: Calculator

Compute the value of a statistic.

Specified by:

calculate in interface Calculator<NullSupportingData>

Parameters:

dependencies - The Map of Statistic to its Calculator.

Returns:

The CalculatedValue for the statistic.
