IsLinksModified Property

Summary

Indicates whether the links for this page have been replaced.

Syntax

C++/CLI

Java

Python

public bool IsLinksModified {get; set;}

public:  
   property bool IsLinksModified 
   { 
      bool get() 
      void set(bool value) 
   }

public boolean isLinksModified() 
public void setLinksModified(boolean value)

IsLinksModified # get and set (DocumentPage)

Property Value

true if the links for this page has been replaced; otherwise, false.

Remarks

GetLinks is used to get the links found in this page. Not all document types support this method. For more information, refer to DocumentStructure.

SetLinks is used to replace the links of the page. IsLinksModified is used as a flag that indicates that the links of this page have been replaced by the user.

This value is saved and re-loaded when the owner LEADDocument uses the cache (LEADDocument.HasCache is true).

IsLinksModified is not used by the framework in any special way, it is a flag that can used to check if the current links are not the same as the original.
