filterList

public RowSetIterator filterList(Map valuesMap,
                                 Row curRow,
                                 ViewCriteria vc)

Advanced internal method.

Given a map of attribute names and values that they map to, shorten the data that this list is exposing.

This method establishes a new ViewCriteria on the collection that the list source iterator binding is bound to. Looks up values from the given map based on the Attribute names in the associated list source collection and sets the corresponding values on a new ViewCriteria row that is added to the ViewCriteria and then applied on the collection to filter the collection.

If the filtered list has only one row then that row is assumed as the selected row and list selection index is set to that row.

filterList

public RowSetIterator filterList(Map valuesMap,
                                 Row curRow,
                                 ViewCriteria vc,
                                 ArrayList varvals)

Deprecated. use filterList(Map, Row, ViewCriteria, ArrayList, boolean)

Advanced internal method...may be removed in a future release.

                                 ViewCriteria vc,

                                 boolean exactMatch)

Advanced internal method.

Given a map of attribute names and values that they map to, shorten the data that this list is exposing.

This method establishes a new ViewCriteria on the collection that the list source iterator binding is bound to. Looks up values from the given map based on the Attribute names in the associated list source collection and sets the corresponding values on a new ViewCriteria row that is added to the ViewCriteria based on exactMatch flag and then applied on the collection to filter the collection.

If the filtered list has only one row then that row is assumed as the selected row and list selection index is set to that row.

If exactMatch flag is not on, then each value is appended with a wildChar for LIKE kind of queries to get all possible choices.
