ResultSetJdbcGpsDevice

public class ResultSetJdbcGpsDevice extends AbstractJdbcActiveMirrorGpsDevice (Code)

A gps device that index a jdbc ResultSet to a set of Compass Resources. Each Resource maps to a ResultSet row. The device can handle multiple ResultSets.

The device holds a list of org.compass.gps.device.jdbc.mapping.ResultSetToResourceMapping s (or derived classes like org.compass.gps.device.jdbc.mapping.TableToResourceMapping ). Each one has all the required mappings setting to map the ResultSet with all it's rows to the set of corresponding Resources.

The device can perform active data base mirroring. The mirror operation is enabled only if the mirror flag is enabled, and will execute against each mapping that org.compass.gps.device.jdbc.mapping.ResultSetToResourceMapping.supportsVersioning .

The autoDetectVersionColumnSqlType setting (which defauls to true) will automatically set the version column jdbc type for mappings that support versioning.
