Method Detail

getValue

public ReferencedEnvelope getValue()

Description copied from interface: CalcResult

Actual answer

Specified by:

getValue in interface CalcResult

Overrides:

getValue in class AbstractCalcResult

Returns:

the calculation result as a generic object

isCompatible

public boolean isCompatible(CalcResult targetResults)

Description copied from interface: CalcResult

Returns true if the target results is a compatible type with the current results, with compatible meaning that the two results may be merged.

Specified by:

isCompatible in interface CalcResult

Overrides:

isCompatible in class AbstractCalcResult

Parameters:

targetResults - the second CalcResult Object

Returns:

true if the targetResults can be merged with the current results

merge

public CalcResult merge(CalcResult resultsToAdd)

Description copied from interface: CalcResult

Returns the merged results of two CalcResult. The way in which the results are merged is dependent on the type of the results added. A new instance is created containing the merged results.

For example: merging two min functions would return the smaller of the two values; merging a count and a sum would return an average.

Specified by:

merge in interface CalcResult

Overrides:

merge in class AbstractCalcResult

Returns:

the merged results
