Additional Inherited Members

- Public Member Functions inherited from Storage_Schema
 Storage_Schema ()
 Builds a storage/retrieval algorithm based on a given data schema. Example For example, if ShapeSchema is the class inheriting from Storage_Schema and containing the description of your application data schema, you create a storage/retrieval algorithm as follows: Handle(ShapeSchema) s = new ShapeSchema;

void Write (Storage_BaseDriver &s, const Handle< Storage_Data > &aData) const
 Writes the data aggregated in aData into the container defined by the driver s. The storage operation is performed according to the data schema with which this algorithm is working. Note: aData may aggregate several root objects to be stored together. More...
 
Handle< Storage_DataRead (Storage_BaseDriver &s) const
 Returns the data read from the container defined by the driver s. The retrieval operation is performed according to the data schema with which this algorithm is working. These data are aggregated in a Storage_Data object which may be browsed in order to extract the root objects from the container. More...

static Standard_Boolean CheckTypeMigration (const TCollection_AsciiString &theTypeName, TCollection_AsciiString &theNewName)
 returns True if theType migration is identified the callback support provides a way to read a file with a incomplete schema. ex. : A file contains 3 types a,b and c. The application's schema contains only 2 type a and b. If you try to read the file in the application, you will have an error.To bypass this problem you can give to your application's schema a callback used when the schema dosent know how to handle this type.
