Class UnityEventDispatcherService

Unity-specific implementation of event dispatcher service using in-memory delegate dictionary.
Provides type-safe event subscription, unsubscription, and dispatching functionality using EventDispatcherSignal-derived events. Maintains event subscribers in a dictionary keyed by event type and supports both generic and non-generic event dispatching for flexible event-driven architecture integration within Unity applications.

Methods

Dispatch(EventDispatcherSignal, Type)

Dispatches an event signal using explicit type information for non-generic scenarios.
Invokes all registered callbacks for the specified event type with the provided signal instance. Supports runtime type resolution when generic type information is not available at compile time. Returns early if no subscribers exist.

Declaration
public void Dispatch(EventDispatcherSignal signal, Type type)
Parameters
Type Name Description
EventDispatcherSignal signal

Event signal instance to dispatch to subscribers
Type type

Runtime type information for event signal dispatching

Dispatch<T>(T)

Dispatches an event signal to all subscribed callbacks of the specified type.
Invokes all registered callbacks for the event type with the provided signal instance. Returns early if no subscribers exist for the event type, otherwise executes the entire delegate multicast chain with the signal parameter.

Declaration
public void Dispatch<T>(T signal) where T : EventDispatcherSignal
Parameters
Type Name Description
T signal

Event signal instance to dispatch to subscribers
Type Parameters
Name Description
T

Event signal type derived from EventDispatcherSignal

Subscribe<T>(EventDispatcherSignalDelegate)

Subscribes a callback delegate to receive events of the specified type.
Registers the callback to be invoked when events of type T are dispatched. Creates new event entry if this is the first subscriber for this event type, otherwise adds the callback to existing delegate multicast chain.

Declaration
public void Subscribe<T>(EventDispatcherSignalDelegate callback) where T : EventDispatcherSignal
Parameters
Type Name Description
EventDispatcherSignalDelegate callback

Delegate callback to invoke when events are dispatched
Type Parameters
Name Description
T

Event signal type derived from EventDispatcherSignal

Unsubscribe<T>(EventDispatcherSignalDelegate)

Unsubscribes a callback delegate from receiving events of the specified type.
Removes the callback from the delegate multicast chain for the specified event type. If the event type exists in the dictionary, the callback is removed using delegate subtraction operator for clean unsubscription.

Declaration
public void Unsubscribe<T>(EventDispatcherSignalDelegate callback) where T : EventDispatcherSignal
Parameters
Type Name Description
EventDispatcherSignalDelegate callback

Delegate callback to remove from event subscriptions
Type Parameters
Name Description
T

Event signal type derived from EventDispatcherSignal
