Dictionary of values associated with an [Iterator](classansys_1_1_project_1_1_iterator.xhtml "Pointer to a project location.").

The metadata index is mapping a variable name to a value and type. Each variable has a single type. The metadata of an [Iterator](classansys_1_1_project_1_1_iterator.xhtml "Pointer to a project location.") is obtained through [Iterator::getMeta()](classansys_1_1_project_1_1_iterator.xhtml#affabcdae62ef0ffe44e5ff877f8b3653 "Returns the Metadata for this project item.") and can be accessed/modified as such

```
 it.getMeta().setValue("Temperature",288.)
   it.isDouble() == true
 double t = it.getMeta().getValueDouble("Temperature");
 it.getMeta().setValue("Temperature",288)
   it.isDouble() == false
   it.isInt() == false
 it.getMeta().setValue("Temperature","288")
   it.isString() == true
```

 The metadata changes will be saved in the project index at the next [Project::saveProject()](classansys_1_1_project_1_1_project.xhtml#a5c10d316ae316b4e77b77707986115d5 "Save the currently opened project.")
