Method Detail

combine

public static DatasetFilter combine(DatasetFilter filter,
                                    DatasetFilter other)

Combines two filter in a conjunction.

Description copied from interface: DatasetFilter

Initializes the filter.

Specified by:

init in interface DatasetFilter

Parameters:

context - dataset context information

matches

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.
