在Autodesk Vault 2014中使用VDF(Vault Development Framework) API获取所有文件的属性信息

 
这几天在玩儿Vault API, 从Autodesk Vault 2014开始提供了Vault Development Framework(VDF) API,让开发工作更简单了。在Vault 2013里面可以使用PropertyService 来获取属性(包括属性定义和属性至),在Vault 2014中的VDF API里,我们可以通过PropertyManager来获取。下面代码演示了如何登录到Vault并取得PropertyManager:
前面的文章提到了使用VDF内置的登录对话框登录非常简单,如果你不用使用那个登录框,也可以自己做界面,使用下面的无界面的登录方式:
 
////login with UI
//VDF.Vault.Currency.Connections.Connection connection = VDF.Vault.Forms.Library.Login(new VDF.Vault.Forms.Settings.LoginSettings());
 
//Another way to log into Vault without UI
VDF.Vault.Results.LogInResult results =
		VDF.Vault.Library.ConnectionManager.LogIn(
				"localhost", "Vault", "Administrator", "",
				VDF.Vault.Currency.Connections.AuthenticationFlags.Standard, null);
if (!results.Success)
{
	Console.WriteLine("Login failed. exit...");
	Console.ReadLine();
	return;
}
 
VDF.Vault.Currency.Connections.Connection connection = results.Connection;
 
VDF.Vault.Services.Connection.IPropertyManager propMgr = connection.PropertyManager;

 

这个例子中,我要递归的获取Vault中所有的目录和文件,看到这几个字,我首先想到的就是用FileManager和FolderManager,不过这两个家伙对于获取文件本身,比如checkout并下载等工作来说很好用,我其实只要获取FileInteration进而获取他们的属性,所有FileManager和FolderManager并不是好办法。同事提醒我可以用IEntityOperationManager。 Folder和File等都是Entity,对于这些Entity的操作还有一个更底层的IEntityOperationManager, 其实FileManger和FolderManager也是调用的IEntityOperationManager。通过IEntityOperationManager的GetBrowseChildren方法就可以获取指定entity的所有子实体,就可以实现递归获取所有文件了。

好了,下面是代码:

          }

          }
        }
      }

    }
