Summary

Gets the URL to the original document's physical location.

Syntax
C#
C++/CLI
Java
Python
public Uri Uri {get;} 
public:  
   property System::Uri^ Uri 
   { 
      System::Uri^ get() 
   } 
public URI getUri() 
Uri # get  (LEADDocument) 

Property Value

The URL to the original document physical location.

Remarks

The value of Uri depends on how this document was obtained, as follows:

When this document is saved and re-loaded from the cache using SaveToCache and DocumentFactory.LoadFromCache, then Uri will contain the original value before it was saved.
