nexusrpc.handler._core.ServiceHandler

class documentation

class ServiceHandler:

Constructor: ServiceHandler.from_user_instance(user_instance)

Internal representation of an instance of a user's service handler class.

A service handler is a class decorated with @nexusrpc.handler.service_handler that defines operation handler methods using decorators such as @nexusrpc.handler.operation_handler.

Instances of this class are created automatically from user service implementation instances on creation of a Handler instance, at Nexus handler start time. While the user's class defines operation handlers as factory methods to be called at handler start time, this class contains the OperationHandler instances themselves.

You may create instances of this class manually and pass them to the Handler constructor, for example when programmatically creating Nexus service implementations.

Class Method	`from_user_instance`	Create a `ServiceHandler` from a user service instance.
Class Variable	`operation_handlers`	Undocumented
Class Variable	`service`	Undocumented
Method	`_get_operation_handler`	Return an operation handler, given the operation name.
