Method Detail

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 classJDBCDataStoreFactory
- Parameters:
dataStore
- The datastore.
-
getDatabaseID
public String getDatabaseID()
Description copied from class:JDBCDataStoreFactory
Returns a string to identify the type of the database.Example: 'postgis'.
- Specified by:
getDatabaseID
in classJDBCDataStoreFactory
-
getDisplayName
public String getDisplayName()
Description copied from interface:DataAccessFactory
Name suitable for display to end user.A non localized display name for this data store type.
- Specified by:
getDisplayName
in interfaceDataAccessFactory
- Overrides:
getDisplayName
in classJDBCDataStoreFactory
- Returns:
- A short name suitable for display in a user interface.
-
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.
-
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 classJDBCDataStoreFactory
-
checkDBType
protected boolean checkDBType(Map<String,?> params)
- Overrides:
checkDBType
in classJDBCDataStoreFactory
-
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 classJDBCDataStoreFactory
- Parameters:
dataStore
- The newly created datastore.params
- THe datastore parameters.- Throws:
IOException
-
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.
Subclass implementation may remove any parameters from the map, or may overrwrite any parameters in the map.- Overrides:
setupParameters
in classJDBCDataStoreFactory
- Parameters:
parameters
- Map ofDataAccessFactory.Param
objects.
-
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 classJDBCDataStoreFactory
-
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 classJDBCDataStoreFactory
- Throws:
IOException
