Method Detail

newInstance

public static StatisticCalculations newInstance(DataSource dataSource,
                                SemanticView collectionSemanticView)

newInstance A factory resembling method that instantiates a new instance of the right StatisticCalculations concrete implementation. Currently two types are offered: The one that actually calculates statistics using the Endeca Server, and a mock one that stabs with dummy results (typically used for testing the speed of light).

Parameters:

dataSource -

collectionSemanticView -

Returns:

an instance of StatisticCalculations implementation.
