Constructor Detail

CompositeDatasetFilter

public CompositeDatasetFilter(DatasetFilter... filters)

Creates a conjunction for several filters.

Parameters:

filters - the filters

CompositeDatasetFilter

public CompositeDatasetFilter(java.util.List<? extends DatasetFilter> filters)

Method Detail

combine

public static DatasetFilter combine(DatasetFilter filter,
                                    DatasetFilter other)

Combines two filter in a conjunction.

Parameters:

filter - the first filter

other - the second filter

init

public void init(DatasetFillContext context)

Description copied from interface: DatasetFilter

Initializes the filter.

Specified by:

init in interface DatasetFilter

Parameters:

context - dataset context information

matches

public boolean matches(EvaluationType evaluation)

Description copied from interface: DatasetFilter

Determines whether the current row matches the filter criteria. Matching rows are included in the report, while non-matching rows are skipped.

Specified by:

matches in interface DatasetFilter

Parameters:

evaluation - the evaluation type. Currently only EvaluationType.ESTIMATED is used.

Returns:

true if the row is to be included in the report.
