Properties

BaseClassShouldFilterColumns

Subclass contract: Return true if the base class should filter columns according to SetDesiredColumns. If this property is false, the actual ArchiveRow objects are returned; otherwise a typed copy is made and ColumnData are populated accoprding to DesiredColumns.

Declaration
protected override bool BaseClassShouldFilterColumns { get; }
Property Value
Type Description
bool
Overrides
Remarks

If columns are cheap to get, the subclass can save code by leaving the filtering to this base class. Conversely, if somecolumns are expensive to calculate, the subclass should do the filtering itself to improve performance.

BaseClassShouldFilterEntities

Subclass contract: Return true if the base class should filter columns according to SetDesiredColumns. If this property is false, the actual ArchiveRow objects are returned; otherwise a typed copy is made and ColumnData are populated accoprding to DesiredColumns.

Declaration
protected override bool BaseClassShouldFilterEntities { get; }
Property Value
Type Description
bool
Overrides
Remarks

If columns are cheap to get, the subclass can save code by leaving the filtering to this base class. Conversely, if somecolumns are expensive to calculate, the subclass should do the filtering itself to improve performance.

BaseClassShouldPage

Subclass contract: Return true if the base class should perform filter entities according to SetDesiredEntities. If this property is false, the result set is assumed to represent the chosen entities only.

Declaration
protected override bool BaseClassShouldPage { get; }
Property Value
Type Description
bool
Overrides
Remarks

If rows are cheap to get, the subclass can save code by leaving the filtering to this base class. Conversely, if rows are expensive to calculate, the subclass should do the entity filtering itself to improve performance.

BaseClassShouldSort

We should keep the sort from the rank in the database and not let the base class sort this.

Declaration
protected override bool BaseClassShouldSort { get; }
Property Value
Type Description
bool
