Module FlowSource

Provides classes for modeling functions that return data from (or send data to) potentially untrusted sources. To use this QL library, create a QL class extending DataFlowFunction with a characteristic predicate that selects the function or set of functions you are modeling. Within that class, override the predicates provided by RemoteFlowSourceFunction or RemoteFlowSinkFunction to match the flow within that function.
