Interface Observer

Namespace

Ice.Instrumentation

Assembly

Ice.dll

The base interface for Ice observers.

public interface Observer

Remarks

The Ice runtime calls observers while updating its internal state and does not guard against exceptions they throw. Implementations of this interface and its derived interfaces must not throw exceptions: a thrown exception can leave the Ice runtime in an inconsistent state or terminate the process.

Methods

attach()

This method is called when the instrumented object is created or when the observer is attached to an existing object.

void attach()

detach()

This method is called when the instrumented object is destroyed and as a result the observer detached from the object.

void detach()

failed(string)

Notifies the observer of a failure.

void failed(string exceptionName)

Parameters

exceptionName string

The name of the exception.
