org.apache.cayenne.dba.sqlite.SQLiteAdapter

All Implemented Interfaces:

DbAdapter

public class SQLiteAdapter
extends JdbcAdapter

A SQLite database adapter that works with Zentus JDBC driver. See https://www.zentus.com/sqlitejdbc/ for the driver information. Also look at https://github.com/xerial/sqlite-jdbc for another adapter option.

Method Summary

Modifier and Type	Method	Description
protected void	configureExtendedTypes(ExtendedTypeMap map)	Called from JdbcAdapter.initExtendedTypes(List, List, List, ValueObjectTypeRegistry) to load adapter-specific types into the ExtendedTypeMap right after the default types are loaded, but before the DI overrides are.
String	createFkConstraint(DbRelationship rel)	Returns a SQL string that can be used to create a foreign key constraint for the relationship.
void	createTableAppendColumn(StringBuffer sqlBuffer, DbAttribute column)	Appends AUTOINCREMENT clause to the column definition for generated columns.
protected void	createTableAppendPKClause(StringBuffer sqlBuffer, DbEntity entity)
String	createUniqueConstraint(DbEntity source, Collection<DbAttribute> columns)	Returns a DDL string to create a unique constraint over a set of columns.
SQLAction	getAction(Query query, DataNode node)	Uses JdbcActionBuilder to create the right action.
SQLTreeProcessor	getSqlTreeProcessor()

Method Details

configureExtendedTypes

protected void configureExtendedTypes(ExtendedTypeMap map)

Description copied from class: JdbcAdapter

Called from JdbcAdapter.initExtendedTypes(List, List, List, ValueObjectTypeRegistry) to load adapter-specific types into the ExtendedTypeMap right after the default types are loaded, but before the DI overrides are. This method has specific implementations in JdbcAdapter subclasses.

Overrides:

configureExtendedTypes in class JdbcAdapter

getSqlTreeProcessor

public SQLTreeProcessor getSqlTreeProcessor()

Specified by:

getSqlTreeProcessor in interface DbAdapter

Overrides:

getSqlTreeProcessor in class JdbcAdapter

Returns:

SQLTreeProcessor that can adjust SQL tree to specific database flavour

Since:

4.2

createFkConstraint

public String createFkConstraint(DbRelationship rel)

Description copied from class: JdbcAdapter

Returns a SQL string that can be used to create a foreign key constraint for the relationship.

Specified by:

createFkConstraint in interface DbAdapter

Overrides:

createFkConstraint in class JdbcAdapter

createUniqueConstraint

public String createUniqueConstraint(DbEntity source,
 Collection<DbAttribute> columns)

Description copied from class: JdbcAdapter

Returns a DDL string to create a unique constraint over a set of columns.

Specified by:

createUniqueConstraint in interface DbAdapter

Overrides:

createUniqueConstraint in class JdbcAdapter

getAction

public SQLAction getAction(Query query,
 DataNode node)

Description copied from class: JdbcAdapter

Uses JdbcActionBuilder to create the right action.

Specified by:

getAction in interface DbAdapter

Overrides:

getAction in class JdbcAdapter

createTableAppendColumn

public void createTableAppendColumn(StringBuffer sqlBuffer,
 DbAttribute column)

Appends AUTOINCREMENT clause to the column definition for generated columns.

Specified by:

createTableAppendColumn in interface DbAdapter

Overrides:

createTableAppendColumn in class JdbcAdapter

Parameters:

sqlBuffer - the StringBuffer to append the column type to

column - the DbAttribute defining the column to append type for

createTableAppendPKClause

protected void createTableAppendPKClause(StringBuffer sqlBuffer,
 DbEntity entity)

Overrides:

createTableAppendPKClause in class JdbcAdapter
