Class AggregateDispatcher<TBase, TResult>
Calls different function delegates (with enumerable return values) based on the runtime types of objects. Aggregates results when multiple delegates match a type (through inheritance).
public class AggregateDispatcher<TBase, TResult> where TBase : class
Type Parameters
TBase
The common base type of all objects to be dispatched.
TResult
The enumerable return values of the delegates.

Methods
Add<TSpecific>(Func<TSpecific, IEnumerable<TResult>>)
Adds a dispatch delegate.
public AggregateDispatcher<TBase, TResult> Add<TSpecific>(Func<TSpecific, IEnumerable<TResult>> function) where TSpecific : class, TBase
Parameters
function
Func<TSpecific, IEnumerable<TResult>>The delegate to call.
Returns
- AggregateDispatcher<TBase, TResult>
The "this" pointer for use in a "Fluent API" style.
Type Parameters
TSpecific
The specific type to call the delegate for. Matches all subtypes as well.
Dispatch(IEnumerable<TBase>)
Dispatches for each element in a collection. Set up with Add<TSpecific>(Func<TSpecific, IEnumerable<TResult>>) first.
public IEnumerable<TResult> Dispatch(IEnumerable<TBase> elements)
Parameters
elements
IEnumerable<TBase>The elements to be dispatched.
Returns
- IEnumerable<TResult>
The values returned by the matching delegates.
Dispatch(TBase)
Dispatches an element to all delegates matching the type. Set up with Add<TSpecific>(Func<TSpecific, IEnumerable<TResult>>) first.
public IEnumerable<TResult> Dispatch(TBase element)
Parameters
element
TBaseThe element to be dispatched.
Returns
- IEnumerable<TResult>
The values returned by all matching delegates aggregated.
GetEnumerator()
Returns an enumerator that iterates through the collection.
public IEnumerator<Func<TBase, IEnumerable<TResult>>> GetEnumerator()
Returns
- IEnumerator<Func<TBase, IEnumerable<TResult>>>
An enumerator that can be used to iterate through the collection.
