Classes

AttributePath	The attribute of the tracked value holding the taint. This is usually “no attribute”. Used for tracking tainted attributes of objects.
NamedAttributePath	The `AttributePath` for an attribute.
NoAttribute	The `AttributePath` for no attribute.
TaintTrackingContext	The context for taint-tracking. There are two types of contexts: * No context; the context at a source. * Tainted parameter; tracks the taint and attribute-path for a parameter Used to track taint through calls accurately and reasonably efficiently.
TaintTrackingImplementation	The implementation of taint-tracking Each `TaintTrackingImplementation` is also a `TaintTracking::Configuration` It is implemented as a separate class for clarity and to keep the code in `TaintTracking::Configuration` simpler.
TaintTrackingNode	A class representing the (node, context, path, kind) tuple. Used for context-sensitive path-aware taint-tracking.

Datatypes

TTaintTrackingContext
TTaintTrackingNode	Type representing the (node, context, path, kind) tuple. Construction of this type is mutually recursive with `TaintTrackingImplementation.flowStep(...)`
