Detailed Description

persistent implementation of storage.

The application must redefine one the two Make() methods. The first one, if the application wants to put only one document in the storage file.

The second method should be redefined to put additional document that could be used by the retrieval instead of the principal document, depending on the schema used during the retrieval. For example, a second document could be a standard CDMShape_Document. This means that a client application will already be able to extract a CDMShape_Document of the file, if the Shape Schema remains unchanged.

Warning! raises DriverError if an error occurs during inside the Make method. stores the content of the Document into a new file.

by default Write will use Make method to build a persistent document and the Schema method to write the persistent document.

Implements PCDM_Writer.

Reimplemented in XmlLDrivers_DocumentStorageDriver, and BinLDrivers_DocumentStorageDriver.

◆ Write() [2/2]

virtual void PCDM_StorageDriver::Write	(	const Handle< CDM_Document > &	theDocument,
		Standard_OStream &	theOStream,
		const Message_ProgressRange &	theRange = `Message_ProgressRange()`
	)
