====== For Each Category ======

===== Description =====

Container that executes the functors it contains once for every class or category present in a categorical map.

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Map  | [[Categorical Map Type]]  | Map of classes or categories the contained functors are executed for.  |

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

None.

===== Outputs =====

None.

===== Internal Outputs =====

^ Name  ^ Type  ^ Description  ^
| Step  | [[Integer Value Type]]  | Category being processed in the current execution.  |

===== Group =====

[[Functor List#Control | Control]]

===== Notes =====

Executions for different categories can run simultaneously when there is no dependency between them.

When Map has zero categories and a result produced by the contained functors is used outside the container, connect a matching [[functor_list#junction|junction]] after the container, so a value still reaches the rest of the model if there are no categories to process.

See Lesson 14, "Using For Each Category and Region Manager," for a practical example of this functor.
