Provides mechanism for automatic locking of DataModel objects

Inheritance Hierarchy

Syntax

C#
C++/CLI

public sealed class SafetyPoint

public ref class SafetyPoint sealed

Remarks

The mechanism is enabled since creation and until disposing of a SafetyPoint object, so the recommended way is to use it with 'using' keyword

Example

var project = new ProjectManager {LockProjectByDefault = false}.OpenProject(@"$(MD_PROJECTS)\EPLAN-DEMO.elk");

//view placement '8' (on page =EB3+ETM/4)
ViewPlacement viewPlacement8 = project
    .Pages[42]
    .AllFirstLevelPlacements
    .OfType<ViewPlacement>()
    .FirstOrDefault(item => item.Properties.DMG_VIEWPLACEMENT_DESIGNATION.ToString() == "8");

using (SafetyPoint safetyPoint = SafetyPoint.Create())
{                
    Console.WriteLine(viewPlacement8.IsLocked);     //false
    viewPlacement8.Scale = 44.44;                   //set another scale
    Console.WriteLine(viewPlacement8.IsLocked);     //true                   
    safetyPoint.Commit();                           //necessary, otherwise changes from the block are rolled-back
}
Console.WriteLine(viewPlacement8.IsLocked);         //again false
