object ← Attribute ← EventTopicAttribute ← EventTopicAttribute<TEntity>

Inherited Members ​

EventTopicAttribute.Topic, EventTopicAttribute.Domain, EventTopicAttribute.Subdomain, EventTopicAttribute.Version, EventTopicAttribute.Internal, EventTopicAttribute.ShouldPluralizeTopicName, EventTopicAttribute.CollapseTopicOnDomain, Attribute.GetCustomAttributes(MemberInfo, Type), Attribute.GetCustomAttributes(MemberInfo, Type, bool), Attribute.GetCustomAttributes(MemberInfo), Attribute.GetCustomAttributes(MemberInfo, bool), Attribute.IsDefined(MemberInfo, Type), Attribute.IsDefined(MemberInfo, Type, bool), Attribute.GetCustomAttribute(MemberInfo, Type), Attribute.GetCustomAttribute(MemberInfo, Type, bool), Attribute.GetCustomAttributes(ParameterInfo), Attribute.GetCustomAttributes(ParameterInfo, Type), Attribute.GetCustomAttributes(ParameterInfo, Type, bool), Attribute.GetCustomAttributes(ParameterInfo, bool), Attribute.IsDefined(ParameterInfo, Type), Attribute.IsDefined(ParameterInfo, Type, bool), Attribute.GetCustomAttribute(ParameterInfo, Type), Attribute.GetCustomAttribute(ParameterInfo, Type, bool), Attribute.GetCustomAttributes(Module, Type), Attribute.GetCustomAttributes(Module), Attribute.GetCustomAttributes(Module, bool), Attribute.GetCustomAttributes(Module, Type, bool), Attribute.IsDefined(Module, Type), Attribute.IsDefined(Module, Type, bool), Attribute.GetCustomAttribute(Module, Type), Attribute.GetCustomAttribute(Module, Type, bool), Attribute.GetCustomAttributes(Assembly, Type), Attribute.GetCustomAttributes(Assembly, Type, bool), Attribute.GetCustomAttributes(Assembly), Attribute.GetCustomAttributes(Assembly, bool), Attribute.IsDefined(Assembly, Type), Attribute.IsDefined(Assembly, Type, bool), Attribute.GetCustomAttribute(Assembly, Type), Attribute.GetCustomAttribute(Assembly, Type, bool), Attribute.Equals(object?), Attribute.GetHashCode(), Attribute.Match(object?), Attribute.IsDefaultAttribute(), Attribute.TypeId, object.GetType(), object.MemberwiseClone(), object.ToString(), object.Equals(object?), object.Equals(object?, object?), object.ReferenceEquals(object?, object?), object.GetHashCode()

Examples ​

[EventTopic<User>(domain: "identity")]
public record UserCreatedEvent(Guid Id);
// Results in topic: "users"

Remarks ​

This generic version automatically generates a topic name from the entity type name, converting it to kebab-case. For example, UserAccount becomes user-accounts.

Constructors ​
