org.compass.gps.device.jdbc.mapping .ResultSetToResourceMapping

All known Subclasses:   org.compass.gps.device.jdbc.mapping .TableToResourceMapping,
ResultSetToResourceMapping
public class ResultSetToResourceMapping (Code)
Maps a Jdbc ResultSet to a Compass Resource.
The required mappings are the alias of the Resource, the select query that generates the ResultSet, and at least one id mapping that maps the ResultSet identifiers columns ( org.compass.gps.device.jdbc.mapping.IdColumnToPropertyMapping ).
Mapping data columns ( org.compass.gps.device.jdbc.mapping.DataColumnToPropertyMapping ) is optional, but provides the meta data (Resource Proeprty) for searching. You can also enable (which is disabled by default) for indexing all the un mapped columns of the ResultSet using the ResultSetToResourceMapping.setIndexUnMappedColumns(boolean) .
For real time mirroring, the version query and at least one version column mapping ( org.compass.gps.device.jdbc.mapping.VersionColumnMapping ) is required.
