Class DelayedActionRenderer<T>

An IActionRenderer<T> version of DelayedRenderer<T>.

Decorates an IActionRenderer<T> instance and delays the events until blocks are confirmed the certain number of blocks. When blocks are recognized the delayed events relevant to these blocks are relayed to the decorated IActionRenderer<T>.

Syntax
public class DelayedActionRenderer<T> : DelayedRenderer<T>, IActionRenderer<T>, IRenderer<T> where T : IAction, new()
Type Parameters
Name Description
T

An IAction type. It should match to BlockChain<T>'s type parameter.
Examples
IStore store = GetStore();
IActionRenderer<ExampleAction> actionRenderer = new SomeActionRenderer();
// Wraps the actionRenderer with DelayedActionRenderer; the SomeActionRenderer instance
// becomes to receive event messages only after the relevent blocks are confirmed
// by 3+ blocks.
actionRenderer = new DelayedActionRenderer<ExampleAction>(
   actionRenderer,
   store,
   confirmations: 3);
// You must pass the same store to the BlockChain<T>() constructor:
var chain = new BlockChain<ExampleAction>(
   ...,
   store: store,
   renderers: new[] { actionRenderer });
