public class ExpressionStatementNode
extends Node

A node for an expression that is used as a statement.

   expression;
 

An ExpressionStatementNode appears in the CFG after the node(s) of the expression. The node can be used for special-handling of expression statements or can be seen as a no-op marker node.
