captureTracingContext() → Object?: Returns the current tracing context and is called just before a message is sent from an user to a worker isolate.
inherited
close() → FutureOr<void>: Called after this delegate is no longer used as the current delegate.
inherited
createWorkerDelegate() → TracingDelegate: Creates a new TracingDelegate to be used for a worker isolate, which is about to be created by the current isolate.
override
initialize() → FutureOr<void>: Called before this delegate is used as the current delegate.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onTraceData(Object? data) → void: Callback for receiving trace data from delegates in worker isolates.
inherited
restoreTracingContext(Object? context, void restore()) → void: Restores the tracing context and is called just after a message from a user isolate is received by a worker isolate.
inherited
sendTraceData(Object? data) → void: Allows this delegate to send arbitrary data to the delegate it was created by.
inherited
toString() → String: A string representation of this object.
inherited
traceAsyncOperation<T>(TracedOperation operation, Future<T> execute()) → Future<T>: Called when an asynchronous operation trace point is reached.
override
traceSyncOperation<T>(TracedOperation operation, T execute()) → T: Called when a synchronous operation trace point is reached.
override

defaultOperationDetailsResolver(TracedOperation operation) → Map<String, Object?>?: The default function to resolve details of a TracedOperation for its timeline events.
defaultOperationFilter(TracedOperation operation) → bool: The default filter that is used to determine whether an operation should be recorded to the timeline.
defaultOperationNameResolver(TracedOperation operation) → String: The default function to resolve the name of a TracedOperation for its timeline events.
