Name

NestedContext

Purpose

Allows a loop expression to be nested in this loop expression.

Description

This function can be used only in the Contexts argument of a loop expression and specifies a loop expression to be nested in this loop expression.

When referencing input loops, every level of input looping that is an ancestor to the referenced loop must have a corresponding loop expression in the output. The nesting capability provides a way to refer to multiple input loops within a single loop expression.

Though this function specifies variable arguments, it can have exactly one argument, which is a loop function.
