IInterval Interface

This interface exposes a method to get the limits of an interval.

IInterval Members

GetLimits When a condition tree expresses that the value of a property must fall in a certain range, it can be expressed as a leaf node. This is done by having the value of the node being a PROPVARIANT with tag VT_UNKNOWN and a punkVal that is a pointer to an object implementing IInterval. IInterval specifies the lower and upper limits of the interval, each of which may be infinite or a specific value.
