Method Summary

All Methods Static Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`static DispatchEventMapper`	`discardEvents()`	Create a `DispatchEventMapper` that processes updates and records them into the right `Store`, while not producing any `Event` downstream.
`static DispatchEventMapper`	`emitEvents()`	Create a `DispatchEventMapper` that processes updates and records them into the right `Store`, then derives the proper `Event`.
`<D,S,E extends Event> Mono<E>`	`handle(DispatchContext<D,S> context)`	Process a `DispatchContext` to potentially obtain an `Event`.
`static DispatchEventMapper`	`noOp()`	Create a `DispatchEventMapper` that doesn't process any dispatches

- Method Detail
  - handle
```
<D,S,E extends Event> Mono<E> handle(DispatchContext<D,S> context)
```
    Process a DispatchContext to potentially obtain an Event.
    
    Type Parameters:
    
    D - the Dispatch type
    
    E - the resulting Event type
    
    Parameters:
    
    context - the DispatchContext used with this Dispatch object
    
    Returns:
    
    a Mono of Event mapped from the given DispatchContext object, or empty if no Event is produced. If an error occurs during processing, it is emitted through the Mono.
  - emitEvents
```
static DispatchEventMapper emitEvents()
```
    Create a DispatchEventMapper that processes updates and records them into the right Store, then derives the proper Event.
    
    Returns:
    
    a DispatchEventMapper that caches updates and produces Event instances
  - discardEvents
```
static DispatchEventMapper discardEvents()
```
    Create a DispatchEventMapper that processes updates and records them into the right Store, while not producing any Event downstream.
    
    Returns:
    
    a DispatchEventMapper that only caches updates
  - noOp
```
static DispatchEventMapper noOp()
```
    Create a DispatchEventMapper that doesn't process any dispatches
    
    Returns:
    
    a DispatchEventMapper that does nothing
