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. | ||
| Java Source File Name | Type | Comment |
| Column.java | Class | Represents a database column. |
| ColumnIO.java | Class | Metadata about column I/O in a specific context. |
| Constraint.java | Class | A table constraint. |
| DataSourceFactory.java | Class | Factory for DataSource objects. |
| DriverDataSource.java | Interface | A DataSource that allows additional configuration options to be set into it, so that it can wrap a JDBC driver or other DataSource. |
| DynamicSchemaFactory.java | Class | Factory whose schema group dynamically fills itself with information
as mappings validate themselves in their map method.
Tables are added when
SchemaGroup.findTable is called. |
| FileSchemaFactory.java | Class | Factory that uses an XML schema file to construct the system schema. |
| ForeignKey.java | Class | Represents a database foreign key; may be a logical key with no database representation. |
| Index.java | Class | Represents a database index. |
| LazySchemaFactory.java | Class | Factory that uses database metadata to construct the system schema. The lazy schema factory only loads table data as it is requested. |
| LocalConstraint.java | Class | Constraint over local table columns, as opposed to a foreign key which spans tables. |
| NameSet.java | Class | Name sets track what names have been taken, ignoring case. |
| PrimaryKey.java | Class | Represents a table primary key. |
| ReferenceCounter.java | Class | Some schema components count references so that unused components can be detected. |
| Schema.java | Class | Represents a database schema. |
| SchemaFactory.java | Interface | Factory for SchemaGroup s. |
| SchemaGenerator.java | Class | The SchemaGenerator creates Schema s matching the current database. |
| SchemaGroup.java | Class | Represents a grouping of schemas used in a database. |
| SchemaParser.java | Interface | Interface class for parers that read schema information. |
| Schemas.java | Class | Helper class to deal with schemas. |
| SchemaSerializer.java | Interface | Interface for schema serializers. |
| SchemaTool.java | Class | The SchemaTool is used to manage the database schema. |
| Sequence.java | Class | Represents a database sequence. |
| SimpleDriverDataSource.java | Class | Non-pooling driver data source. |
| Table.java | Class | Represents a database table. |
| TableSchemaFactory.java | Class | Factory that uses an XML schema definition stored in a database table to record the system schema. |
| Unique.java | Class | Represents a unique constraint. |
| XMLSchemaParser.java | Class | Custom SAX parser used to parse Schema objects. |
| XMLSchemaSerializer.java | Class | Serializes Schema s to XML matching the document type definition defined by the XMLSchemaParser . |
