Class ControlFlow::Node

A control flow node.

Either a callable entry node (EntryNode), a callable exit node (ExitNode), or a control flow node for a control flow element, that is, an expression or a statement (ElementNode).

A control flow node is a node in the control flow graph (CFG). There is a many-to-one relationship between ElementNodes and ControlFlowElements. This allows control flow splitting, for example modeling the control flow through finally blocks.

Only nodes that can be reached from the callable entry point are included in the CFG.
