Type Parameters

TExtensionInstance

TExtensionFactory

TMetadataView

Parameters

lazyFactories: IEnumerable<Lazy<TExtensionFactory,TMetadataView>>

Lazy references that will be evaluated.

getter: Func<TExtensionFactory,TExtensionInstance>

Delegate which constructs an instance of the extension from each element of lazyFactories.

dataContentType: IContentType

Target content type.

errorSource: Object

Reference to the object that will be blamed for potential exceptions.

Returns

List<TExtensionInstance>

The list of results of getter.
