Detailed Description

A base class for delegating session I/O.

Sessions sometimes need to import and export additional state beyond a list of operations. For example, when it is not possible to store SMTK UUIDs as modeling-kernel-native attributes, the session may keep an array of UUIDs in order of iteration.

Sessions should not have methods tied to any particular format (e.g., JSON, XML, etc.); so we provide this base class. To use this class:

• format-and-session-specific subclasses of this base class should be written; and
• the session subclass should override its createIODelegate() method to return instances of the above as required.

Note that the I/O format being handled will dictate additional subclass methods to be implemented.

Member Function Documentation

referencePath()

std::string smtk::model::SessionIO::referencePath ( ) const

inline

Return a reference directory to use during import/export.

Any relative file or directory specification should be relative to this reference path. This is used during export to turn absolute paths into relative ones. It may be used during import to do the reverse.
