====== For Each ======

===== Description =====

Container that executes the functors it contains once for every entry of a given table or lookup table, making each entry's key available to its contents through the internal output port Step.

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Elements  | [[Base Table Type]]  | Table or lookup table whose entries the contained functors are executed for.  |

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

^ Name  ^ Type  ^ Description  ^ Default Value  ^
| Sequence Input  | [[None Type]]  | Ensures that the functor connected to this port finishes executing before this container starts.  | None  |

===== Outputs =====

^ Name  ^ Type  ^ Description  ^
| Sequence Output  | [[None Type]]  | Connect this port to another container's Sequence Input to make this container finish executing before that other container starts.  |

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

^ Name  ^ Type  ^ Description  ^
| Step  | [[Real Value Type]]  | Key of the current element being processed.  |

===== Group =====

[[Functor List#Control | Control]]

===== Notes =====

Execution only takes place for entries whose key is greater than or equal to zero and whose associated value is non-zero; other entries in Elements are skipped.

Execution for multiple keys may happen simultaneously when there is no dependency between them.

When Elements can be empty 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 entries to process.

This functor was previously known as "ParallelForEach"; that name is still accepted for backward compatibility with existing scripts.
