+# NearestPointLayeredSideIntegralFunctor
+
+This object is the same as [NearestPointLayeredSideIntegral.md], but the layered integral may be taken
+of any [functor](Functors/index.md), not just a variable.
+
+!alert note title=Functor requirements
+This object requires the `ElemSideQpArg` [functor spatial argument](Functors/index.md) to be
+implemented for the [!param](/UserObjects/NearestPointLayeredSideIntegralFunctor/functor) parameter.

 ## MOOSE Improvements
 
+### Nearest-point layered side integrals for functors
+
+[NearestPointLayeredSideIntegralFunctor.md] was added, which extends
+[NearestPointLayeredSideIntegral.md] to accept any [functor](Functors/index.md),
+not just variables.
