Data Management
Data Sources
The DataManager class has a property called DataSourceManager. This property
provides access to the product family implementation of IDataSourceManager.
IDataSourceManager manages the product family data in the form of IDataSource
implementations.
IDataSource Interface
The IDataSource implementation provides properties that identify the object through a
unique string and the class implementing the data source through its
ImplementationName. It also has a property, IsDirty, that indicates that the
underlying data for the object has changed state and needs to be saved. IDataSource
includes methods to open and close the data source and a method to save data to the
data source. Lastly there is a method to set the identity of the IDataSourceManager
for the object. It has an event, IsDirtyChanged, which will be raised when the
IsDirty property changes to true. IDataSource inherits from IDroidResolver,
which can resolve a Droid into an object reference. IDataSource is defined as:
public interface IDataSource : IDroidResolver
{
string Id { get; }
string ImplementationName { get; }
bool IsDirty { get; }
void Open();
void Close();
void Save();
void SetManager(IDataSourceManager dataSourceManager);
}
event EventHandler IsDirtyChanged;
public interface IDroidResolver
{
bool CanResolve (Droid droid);
object Resolve (Droid droid);
}
