Method Detail

query

public void query(GroupByQuery query)

Description copied from interface: QueryMetrics

Pulls all information from the query object into dimensions of future metrics.

Specified by:

query in interface QueryMetrics<GroupByQuery>

Overrides:

query in class DefaultQueryMetrics<GroupByQuery>

numDimensions

public void numDimensions(GroupByQuery query)

Description copied from interface: GroupByQueryMetrics

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

Specified by:

numDimensions in interface GroupByQueryMetrics

numMetrics

public void numMetrics(GroupByQuery query)

Description copied from interface: GroupByQueryMetrics

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

Specified by:

numMetrics in interface GroupByQueryMetrics

numComplexMetrics

public void numComplexMetrics(GroupByQuery query)

Description copied from interface: GroupByQueryMetrics

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.

Specified by:

numComplexMetrics in interface GroupByQueryMetrics

granularity

public void granularity(GroupByQuery query)

Description copied from interface: GroupByQueryMetrics
