diagnostic_events library

Classes

AsEventHandler<T extends DiagnosticEvent>: Adapter class to use an EventHandlerFunction as a DiagnosticEventHandler. Since this class inherits TypedEventHandler it can filter on event type.
ClientCallOpContext: The context of a client call operation. Subclasses represent web, method, and method streaming calls.
DiagnosticEvent: Base interface for all diagnostic events.
DiagnosticEventContext: Base class for information about the context in which a DiagnosticEvent was submitted.
DiagnosticEventHandler: Base interface for DiagnosticEvent handlers.
DiagnosticEventRecord<E extends DiagnosticEvent>: A record with a submitted diagnostic event.
ExceptionEvent: An event that represents an exception that occurred in the server.
ExceptionHandler: A DiagnosticEventHandler that handles ExceptionEvent instances.
FutureCallOpContext: The context of a future call operation.
MethodCallOpContext: The context of a method call operation.
OperationEventContext: Represents the operation that the event was caused by or in relation to. An operation is a client-originated call / operation or a scheduled operation, i.e. a method call, a streaming call, a web call, or a future call.
StreamOpContext: The context of a stream operation / message.
TypedEventHandler<T extends DiagnosticEvent>: A DiagnosticEventHandler that handles events of a specific type.
WebCallOpContext: The context of a web call operation.

OperationType: Represents the type of "operation" during which the event was caused.
OriginSpace: Denotes whether an event's origin is application (user) space or framework space.

EventHandlerFunction<T extends DiagnosticEvent> = void Function(T event, {required DiagnosticEventContext context, required OriginSpace space}): Function signature type for functions that handle a DiagnosticEvent.
