ExpressionListener Class
This page contains documentation for advanced Fuse features, so we have
taken the liberty to tick the "Show advanced things" checkbox above for
you in advance to be able to provide you with some additional information.
A base class for common expression subscriptions. This handles the basic bookkeeping. Derived classes should implement OnArguments (coming from the base class). The members ClearData and SetData should be called to set the output state.
Using this directly is unsual, consider ComputeExpression instead.
