Package org.apache.ojb.broker.platforms Description

This package contains classes that provide compatibility to a range of RDBM platforms.

The Platform interface provides callbacks that allow to perform RDBMS Platform specific operations whereever neccessary.

The class PlatformDefaultImpl implements Platform and provides default implementations of all methods.

For each supported Platform Xxx there is a class PlatformXxxImpl which extends PlatformDefaultImpl and may override the methods of the baseclass.

The factory class PlatformFactory can be used to create Platform instances. It uses information from a JdbcConnectionDescriptor to select the appropriate PlatformXxxImpl class.

Patterns applied: Configurable Factory, Strategy, Bridge

Todo: Provide more Platform-Implementations
