Package org.apache.openjpa.jdbc.schema

OpenJPA-JDBC Schema Management

This package provides utilities for managing the schema of persistent objects stored in a relational database.

Schema components themselves are little more than standard Java beans. Helper classes are responsible for added functionality such as XML serialization/deserialization, etc.

Interface Summary

Interface	Description
DriverDataSource	A DataSource that allows additional configuration options to be set into it, so that it can wrap a JDBC driver or other DataSource.
SchemaFactory	Factory for SchemaGroups.
SchemaGenerator.Listener	A listener for a potentially lengthy schema generation process.
SchemaParser	Interface class for parers that read schema information.
SchemaSerializer	Interface for schema serializers.

Class Summary

Class	Description
AutoDriverDataSource	Automatic Commons DBCP pooling or Simple non-pooling driver data source.
Column	Represents a database column.
ColumnIO	Metadata about column I/O in a specific context.
Constraint	A table constraint.
DataSourceFactory	Factory for DataSource objects.
DBCPDriverDataSource	Commons DBCP basic pooling driver data source.
DynamicSchemaFactory	Factory whose schema group dynamically fills itself with information as mappings validate themselves in their map method.
FileSchemaFactory	Factory that uses an XML schema file to construct the system schema.
ForeignKey	Represents a database foreign key; may be a logical key with no database representation.
ForeignKey.FKMapKey
Index	Represents a database index.
LazySchemaFactory	Factory that uses database metadata to construct the system schema.
LocalConstraint	Constraint over local table columns, as opposed to a foreign key which spans tables.
NameSet	Name sets track what names have been taken, ignoring case.
PrimaryKey	Represents a table primary key.
Schema	Represents a database schema.
SchemaGenerator	The SchemaGenerator creates Schemas matching the current database.
SchemaGenerator.Event	An event corresponding to the generation of a schema object.
SchemaGroup	Represents a grouping of schemas used in a database.
Schemas	Helper class to deal with schemas.
SchemaTool	The SchemaTool is used to manage the database schema.
SchemaTool.Flags	Run flags.
Sequence	Represents a database sequence.
SimpleDriverDataSource	Non-pooling driver data source.
Table	Represents a database table.
TableSchemaFactory	Factory that uses an XML schema definition stored in a database table to record the system schema.
Unique	Represents a unique constraint.
XMLSchemaParser	Custom SAX parser used to parse Schema objects.
XMLSchemaParser.UniqueInfo	Used to hold unique constraint info before it is resolved.
XMLSchemaSerializer	Serializes Schemas to XML matching the document type definition defined by the XMLSchemaParser.
