Method Detail

start

public <T> SimpleContext<?> start(DebugNotification<T> n)

Description copied from class: DebugNotificationListener

For each DebugNotification.Kind start is invoked before the actual method is invoked.

This can be used to perform extra logging, metrics and other such things.

Overrides:

start in class DebugNotificationListener<SimpleContext<?>>

Parameters:

n - DebugNotification containing the data and context about what is happening.

Returns:

A contextual object that the listener can use in the DebugNotificationListener.complete(Object) or DebugNotificationListener.error(Object, Throwable) after the actual operation has ended.

complete

public void complete(SimpleContext<?> context)

Description copied from class: DebugNotificationListener

After the actual operations has completed from DebugNotificationListener.start(DebugNotification) this is invoked

Overrides:

complete in class DebugNotificationListener<SimpleContext<?>>

error

public void error(SimpleContext<?> context,
         java.lang.Throwable e)

Description copied from class: DebugNotificationListener

After the actual operations has thrown an exception from DebugNotificationListener.start(DebugNotification) this is invoked

Overrides:

error in class DebugNotificationListener<SimpleContext<?>>

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toString

public java.lang.String toString(java.util.SortedSet<SimpleDebugNotificationListener.NotificationsByObservable<?>> notificationsByObservableSnapshot)
