Constructor Details

HanaDataStoreFactory

public HanaDataStoreFactory()

Method Details

getDescription

public String getDescription()

Description copied from interface: DataAccessFactory

Describe the nature of the datasource constructed by this factory.

A non localized description of this data store type.

Returns:

A human readable description that is suitable for inclusion in a list of available datasources.

getDatabaseID

protected String getDatabaseID()

Description copied from class: JDBCDataStoreFactory

Returns a string to identify the type of the database.

Example: 'postgis'.

Specified by:

getDatabaseID in class JDBCDataStoreFactory

getDriverClassName

protected String getDriverClassName()

Description copied from class: JDBCDataStoreFactory

Returns the fully qualified class name of the jdbc driver.

For example: org.postgresql.Driver

Specified by:

getDriverClassName in class JDBCDataStoreFactory

createSQLDialect

protected SQLDialect createSQLDialect(JDBCDataStore dataStore)

Description copied from class: JDBCDataStoreFactory

Creates the dialect that the datastore uses for communication with the underlying database.

Specified by:

createSQLDialect in class JDBCDataStoreFactory

Parameters:

dataStore - The datastore.

getValidationQuery

protected String getValidationQuery()

Description copied from class: JDBCDataStoreFactory

Override this to return a good validation query (a very quick one, such as one that asks the database what time is it) or return null if the factory does not support validation.

Specified by:

getValidationQuery in class JDBCDataStoreFactory

setupParameters

protected void setupParameters(Map<String,Object> parameters)

Description copied from class: JDBCDataStoreFactory

Sets up the database connection parameters.

Subclasses may extend, but should not override. This implementation registers the following parameters.

• JDBCDataStoreFactory.HOST
• JDBCDataStoreFactory.PORT
• JDBCDataStoreFactory.DATABASE
• JDBCDataStoreFactory.SCHEMA
• JDBCDataStoreFactory.USER
• JDBCDataStoreFactory.PASSWD

Subclass implementation may remove any parameters from the map, or may overrwrite any parameters in the map.

Overrides:

setupParameters in class JDBCDataStoreFactory

Parameters:

parameters - Map of DataAccessFactory.Param objects.

getJDBCUrl

protected String getJDBCUrl(Map<String,?> params)
                     throws IOException

Description copied from class: JDBCDataStoreFactory

Builds up the JDBC url in a jdbc:://:/ Override if you need a different setup

Overrides:

getJDBCUrl in class JDBCDataStoreFactory

Throws:

IOException

createDataStoreInternal

protected JDBCDataStore createDataStoreInternal(JDBCDataStore dataStore,
 Map<String,?> params)
                                         throws IOException

Description copied from class: JDBCDataStoreFactory

Subclass hook to do additional initialization of a newly created datastore.

Typically subclasses will want to override this method in the case where they provide additional datastore parameters, those should be processed here.

This method is provided with an instance of the datastore. In some cases subclasses may wish to create a new instance of the datastore, for instance in order to wrap the original instance. This is supported but the new datastore must be returned from this method. If not is such the case this method should still return the original passed in.

Overrides:

createDataStoreInternal in class JDBCDataStoreFactory

Parameters:

dataStore - The newly created datastore.

params - THe datastore parameters.

Throws:

IOException
