====== Number Map ======

===== Description =====

Placeholder used to register a map under a given number in the container it is placed inside. This functor produces no output itself: the enclosing container inspects its input ports and performs the actual registration.

This functor can be placed inside [[Calculate Map]], [[Calculate Categorical Map]], [[Select Map]], and [[Calculate Python Expression]] (where map values are not currently supported, so connecting this hook to that container raises an error at runtime).

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Map  | [[Map Type]]  | Map to register in the container.  |
| Map Number  | [[Positive Integer Value Type]]  | Number under which the map will be known inside the container.  |

===== Optional Inputs =====

None.

===== Outputs =====

None.

===== Group =====

[[Functor List#Map Algebra Supplementary | Map Algebra Supplementary]]

===== Notes =====

This functor's banner shows "Map" followed by the value of Map Number.

Reports a warning if Map Number is provided through a connection rather than as a constant.

Placing this functor inside a container it is not designed for reports a warning, since it has no effect there.
