Droid Class
the Droid string can indicate a local server when the source is local. The Droid is created
with a link to the class that implements IDataSource for its data.
The Droid class is defined as:
public class Droid
{
public Droid (string Droid);
public Droid (string source, string id);
public override bool Equals (object obj);
public static string Escape (string input);
public override int GetHashCode ();
public override string ToString ();
public static string Unescape (string input);
public static Droid Empty { get; }
public string Instance { get; }
public bool IsEmpty { get; }
public string Source { get; }
}
public static bool operator != (Droid left, Droid right);
public static bool operator == (Droid left, Droid right);
The Slb.Ocean.Data.Hosting.ObjectId class provides assistance with Droid
creation. The objects type and identifier, perhaps from its row in a database table, can be
used to create the ObjectId portion of the Droid. The IDataSource.Id property for
the object is combined with this to form the Droid. The Droid class has two public
constructors that will throw an exception for improperly formatted Droid strings.
public MyDomainObj(IDataSource dataSource, string dataType, string id)
{
// Create an object id from the data type and id string
ObjectId objId = new ObjectId(dataType, new String[] { "Id", id });
// Use id from datasource and created object id to create a Droid
Droid m_Droid = new Droid(dataSource.Id, objId.ToString());
}
