Detailed Description

A singleton class that serves as a global registry for Chem.ReactionInputHandler and Chem.ReactionOutputHandler implementation instances.

DataIOManager provides static methods for the registration and lookup of Chem.ReactionInputHandler and Chem.ReactionOutputHandler implementation instances that handle different input and output storage formats.

Input and output handlers are registered by the methods registerInputHandler() and registerOutputHandler(). These methods expect a reference to an instance of the respective handler implementation as an argument (please note that the registered instance must not be destroyed as long as it is accessible via the DataIOManager interface!).

For the removal of registered handlers the unregisterInputHandler() and unregisterOutputHandler() family of overloaded methods is provided. These methods accept a reference to the registered handler instance, the handler index, the handled data format or an iterator pointing to the handler as an argument.

Registered input handlers can be queried by the methods getInputHandlerByFormat(), getInputHandlerByName(), getInputHandlerByFileExtension() and getInputHandlerByMimeType(), which allow to find a suitable handler for a given data format, data format name, file extension or mime-type. For the registered output handlers similar methods are provided.

I/O handlers for data formats and object types supported by the CDPL are registered in the static library initialization code. These built-in handlers are accessible by the linking client code as soon as the library initialization has finished.
