com.yahoo.bard.webservice.table.resolver.DimensionIdFilter

All Implemented Interfaces:

DataSourceFilter, Function<DataSourceConstraint,Boolean>

public class DimensionIdFilter
extends Object
implements DataSourceFilter

An implementation of DataSourceFilter which uses dimensionApiFilters to match partition data sources. The matching algorithm requires that for each dimension specified, the query filters must match one of the corresponding values.

Constructor Detail

DimensionIdFilter

public DimensionIdFilter(Map<Dimension,Set<String>> dimensionMappingValues)

Constructor.

Parameters:

dimensionMappingValues - The map of dimension to sets of dimension values which map this table.

Method Detail

anyRowsMatch

protected boolean anyRowsMatch(@NotNull
                               Dimension dimension,
                               @NotNull
                               Set<ApiFilter> constraintFilters)

Check if for a given set of request filters, adding in the filters for this `DataSourceFilter` there is a corresponding row. This method should never be called with a dimension that isn't a key in dimensionKeySelectFilters

Parameters:

dimension - The dimension whose rows are being tested on.

constraintFilters - The api filters from the constraint

Returns:

true if for this dimension there are rows matching the query filters AND the embedded filters.
