class TaintWarning(object):

View In Hierarchy

A taint warning is a collection of warning messages that occurred during the taint.

A taint warning is composed of:

Warnings may indicate correctness errors due to limitations of the current taint engine. It is recommended to manually check the validity of the taint at points that contain warnings, especially if the warnings occurs in a range of transitions that overlaps with some TaintChange.
