Method Detail

getSelectTranslator

public SelectTranslator getSelectTranslator(SelectQuery<?> query,
                                            EntityResolver entityResolver)

Description copied from interface: DbAdapter

Returns a SelectTranslator that works with the adapter target database.

Specified by:

getSelectTranslator in interface DbAdapter

Overrides:

getSelectTranslator in class OracleAdapter

Since:

4.0

getAction

public SQLAction getAction(Query query,
                           DataNode node)

Uses OracleActionBuilder to create the right action.

Specified by:

getAction in interface DbAdapter

Overrides:

getAction in class OracleAdapter

findResource

protected URL findResource(String name)

Description copied from class: JdbcAdapter

Locates and returns a named adapter resource. A resource can be an XML file, etc.

This implementation is based on the premise that each adapter is located in its own Java package and all resources are in the same package as well. Resource lookup is recursive, so that if DbAdapter is a subclass of another adapter, parent adapter package is searched as a failover.

Overrides:

findResource in class JdbcAdapter

getQualifierTranslator

public QualifierTranslator getQualifierTranslator(QueryAssembler queryAssembler)

Description copied from class: OracleAdapter

Returns a trimming translator.

Specified by:

getQualifierTranslator in interface DbAdapter

Overrides:

getQualifierTranslator in class OracleAdapter
