getValue

public java.lang.Object getValue()

Description copied from interface: CalcResult

Actual answer

Specified by:

getValue in interface CalcResult

Overrides:

getValue in class AbstractCalcResult

getCount

public int getCount()

The count used to calculate the average

Returns:

the count, or -1 if unknown

getSum

public java.lang.Object getSum()

The sum used to calculate the average

Returns:

isCompatible

public boolean isCompatible(CalcResult targetResults)

Determines if the target CalcResult object can be merged with this CalcResult object

Specified by:

isCompatible in interface CalcResult

Overrides:

isCompatible in class AbstractCalcResult

Parameters:

targetResults - a second CalcResult object (target)

Returns:

boolean

merge

public CalcResult merge(CalcResult resultsToAdd)
