It causes side effects (writing to the log/console) and otherwise simply runs its contained functors like any other container. ===== Optional Inputs ===== ^ Name ^ Type ^ Description ^ | Initial Message | [[string_type|String Type]] | Message printed before the container's content is executed. Nullable; the default value is none (nothing is printed). | | Final Message | [[string_type|String Type]] | Message printed after the container's content is executed. Nullable; the default value is none (nothing is printed). | | Log Level | [[log_tag_type|Log Tag Type]] | The log level used to print both messages — for example, distinguishing a normal progress message from an error message. The default value is Unconditional. | ===== Outputs ===== This functor has no output ports; it acts through the side effect of printing to the console. ===== Group ===== [[functor_list#control|Control]] ===== Notes ===== ==== Execution order ==== The initial message, if defined, is printed before the contained functors run; the final message, if defined, is printed only after all contained functors have finished running. Both messages are printed using the same ''logLevel''. ==== Recommended usage ==== Using ''Print'' without any contained functors is not advised — with nothing inside to order its execution against, when the message is actually printed relative to the rest of the model becomes unspecified. ==== String formatting ==== ''Print'' has no string-formatting capabilities of its own. To build a formatted or composite message (embedding a computed value, for example), assemble the string first with [[create_string|Create String]] and connect its result into Initial Message or Final Message; some types are also automatically converted to String when connected directly. ===== Internal Name ===== ''Print''
