Class Sources::SourceNode

A source node for local data flow, that is, a node from which local data flow is tracked.

Examples include function parameters, imports and property accesses; see DataFlow::SourceNode::DefaultRange for details. You can introduce new kinds of source nodes by defining new subclasses of DataFlow::SourceNode::Range.
