Remarks
The Data Designer Extensibility (DDEX) architecture relies heavily on the creation of DDEX provider support entity objects by means of a provider object factory. The creation of these objects is followed by one or more operations to put them within some larger context. The mechanism used to supply context to these objects is to site the object together with one or more additional objects. Additional objects could include an “owner” of the provider object (for example, a data connection object). Or the additional object could just be a global service provider object to enable the provider object access to all other Visual Studio services. Note that it is common for DDEX support entities to have multiple sites.
Examples
The following code demonstrates a customization of the DDEX implementation of the IVsDataConnectionProperties support entity. The code includes an implementation of the IVsDataSiteableObject<T> interface for both the IVsDataProvider object that created it and a global service provider object.
using System;
using Microsoft.VisualStudio.Data.Core;
using Microsoft.VisualStudio.Data.Framework;
internal class MyConnectionProperties : DataConnectionProperties,
IVsDataSiteableObject<IVsDataProvider>,
IVsDataSiteableObject<IServiceProvider>
{
private IVsDataProvider _provider;
private IServiceProvider _serviceProvider;
IVsDataProvider IVsDataSiteableObject<IVsDataProvider>.Site
{
get
{
return _provider;
}
set
{
_provider = value;
}
}
IServiceProvider IVsDataSiteableObject<IServiceProvider>.Site
{
get
{
return _serviceProvider;
}
set
{
_serviceProvider = value;
}
}
}
