JDBC2DataStore

abstract public class JDBC2DataStore extends JDBC1DataStore (Code)

This JDBCDataStore is able to take advantage of additonal functionality provided by JDBC2 level drivers - for example ConnectionPools.

This class provides a default implementation of a JDBC data store. Support for vendor specific JDBC data stores can be easily added to Geotools by subclassing this class and overriding the hooks provided.

At a minimum subclasses should implement the following methods:

JDBC2DataStore.buildAttributeType(ResultSet) buildAttributeType(ResultSet) - This should be overriden to construct an attribute type that represents any column types not supported by the default implementation, such as geometry columns.
JDBC2DataStore.getGeometryAttributeIO(AttributeType,QueryData)getGeometryAttributeIO(AttributeType, QueryData) - Should be overriden to provide a way to read/write geometries into the format of the database

Additionally subclasses can optionally override the following:

Use a specific FIDMapperFactory by overriding the JDBC2DataStore.buildFIDMapperFactory(JDBCDataStoreConfig)buildFIDMapperFactory(JDBCDataStoreConfig) method, and eventually disallow user overrides by throwing an java.lang.UnsupportedOperationException UnsupportedOperationException in the JDBC2DataStore.setFIDMapperFactory(FIDMapperFactory) setFidMapperFactory() method.
JDBC2DataStore.allowTable(String) allowTable - Used to determine whether a table name should be exposed as a feature type.
JDBC2DataStore.determineSRID(String,String) determineSRID - Used to determine the SpatialReference ID of a geometry column in a table.
JDBC2DataStore.buildSQLQuery(String,AttributeType[],Filter,boolean)buildSQLQuery() - Sub classes can override this to build a custom SQL query.
JDBC2DataStore.getResultSetType(boolean) getResultSetType if the standard result set type is not satisfactory/does not work with a normal FORWARD_ONLY resultset type
JDBC2DataStore.getConcurrency(boolean) getConcurrency to set the level of concurrency for the result set used to read/write the database

Additionally subclasses may want to set the value of:

sqlNameEscape - character (String) to surround names of SQL objects to support mixed-case and non-English names.
