Detailed Description

The class represents an interval with lower and upper bound.

Operations on the interval are defined according to the ODMG-93 standard. The operations union, difference, and intersection are defined according to the following table:

| ... fixed bound ... open bound

Attention: The difference operation has to be reconsidered in future concerning a discrete interpretation of the intervals.

The closure operation defines an interval which is the smallest interval containing the two operands. The method intersects_with() returns 0 in the error cases of the intersection operation and 1 otherwise.
