When PowerShell converts objects into readable output, it first checks whether their object type has a predefined view: stored formatting rules targeted at that type. section 11.2
Predefined views provide:
- Special layouts for particular types, such as Microsoft.PowerShell.KeyHandler objects. section 11.2
- Default formatting rules loaded from installed .format.ps1xml files when PowerShell starts. section 11.2
Customize a URI view
A System.Uri object initially displays many properties. A type-data file can define a DefaultDisplayPropertySet containing Scheme, Host, Port, AbsoluteUri, and IsFile; Update-TypeData then applies that definition, producing a shorter view. section 11.2
