Method Detail

configureExtendedTypes

protected final void configureExtendedTypes(org.objectstyle.cayenne.access.types.ExtendedTypeMap map)

Installs appropriate ExtendedTypes used as converters for passing values between JDBC and Java layers.

buildAttribute

public final org.objectstyle.cayenne.map.DbAttribute buildAttribute(String name,
                                                                    String typeName,

createFkConstraint

public final String createFkConstraint(org.objectstyle.cayenne.map.DbRelationship rel)

Throws an exception, since FK constraints are not supported by MySQL.

tableTypeForView

public final String tableTypeForView()

Returns null, since views are not yet supported in MySQL. Views support is promised in MySQL 4.1.

createPkGenerator

protected final org.objectstyle.cayenne.dba.PkGenerator createPkGenerator()

Creates and returns a primary key generator. Overrides superclass implementation to return an instance of MySQLPkGenerator that does the correct table locking.
