Access scope defines the accessibility of items in libraries and classes. Every item in a library or class can be set to either public, protected (classes only), community or private scope. Virtual folders automatically apply their access scope to all contained items.
Public items are accessible by anyone. This is the default access scope in LabVIEW.
Items in protected scope are shown with a yellow key () on the file icon. Protected scope is only available for classes. Methods in protected scope are accessible by the owning class and its descendants.
