Constructor Details

SumAccumulator

public SumAccumulator(Statistic statistic)

Public constructor.

Parameters:

statistic - The Statistic.

Method Details

accumulate

public Accumulator<Void> 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<Void>

Parameters:

quantity - The Quantity to include in the accumulated value.

Returns:

This Accumulator.

accumulate

public Accumulator<Void> accumulate(CalculatedValue<Void> 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<Void>

Parameters:

calculatedValue - The CalculatedValue to include in the accumulated value.

Returns:

This Accumulator.

accumulateAny

public Accumulator<Void> accumulateAny(CalculatedValue<?> 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. If the CalculatedValue's supporting data is of an unsupported type then an IllegalArgumentException will be thrown.

Specified by:

accumulateAny in interface Accumulator<Void>

Parameters:

calculatedValue - The CalculatedValue to include in the accumulated value.

Returns:

This Accumulator.

calculate

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

Description copied from interface: Calculator

Compute the value of a statistic.

Specified by:

calculate in interface Calculator<Void>

Parameters:

dependencies - The Map of Statistic to its Calculator.

Returns:

The CalculatedValue for the statistic.
