Member Functions Documentation

Size()

IMPORT_C TUintSize()const

Returns the size of the class. Used for extensibility by deriving from this base class and adding new member variables. Intended to be used for implementation of methods where this class reference is passed as function arguments. Implementation of such methods can find out the whether the actual class passed is base or the derived one. So, if a new application is made to run on an old implementation, an error may occur once the old implementation detects this by getting the size information of the T class passed. Also, if old application is made to run on a new implementation, this can be handled correctly if the derived class variables handling is done in a proper 'if-else' statement.

Note:

The size will be modified when the T-class gets updated.

Version()

IMPORT_C TUintVersion()const

Returns the version of the class. Used for extensibility specially when the class members are not added but the Reserved members get used at a later stage.

Note:

The version will be modified when the T-class gets updated.
