createTuple 

Creates an ITuple that can be used to retrieve the current position, by using it as an argument of the getTuple method.  

 

getTuple 

Retrieves the current position into an ITuple, which you must create first by invoking the createTuple method.  

 

next 

Moves the current position to the next non-default value, if any.  

 

reset 

Re initializes the iterator: Moves the current position to before the beginning of the data; a subsequent next call will find the first non-default position. If the iterator was in an erroneous state, the reset method will also reset the state to normal.

Verifies whether the given ITuple can be used with the getTuple method. More specifically, it tests whether the given ITuple is compatible with the domain sets of the associated IData object.
