Method Detail

numDimensions

void numDimensions(GroupByQuery query)

Sets the size of GroupByQuery.getDimensions() of the given query as dimension.

numMetrics

void numMetrics(GroupByQuery query)

Sets the number of metrics of the given groupBy query as dimension.

numComplexMetrics

void numComplexMetrics(GroupByQuery query)

Sets the number of "complex" metrics of the given groupBy query as dimension. By default it is assumed that "complex" metric is a metric of not long or double type, but it could be redefined in the implementation of this method.

granularity

void granularity(GroupByQuery query)

Sets the granularity of BaseQuery.getGranularity() of the given query as dimension.
