Net::DBus::Annotation - annotations for changing behaviour of APIs

This module provides a number of annotations which will be useful when dealing with the DBus APIs. There are annotations for switching remote calls between sync, async and no-reply mode. More annotations may be added over time.
dbus_call_sync
Requests that a method call be performed synchronously, waiting for the reply or error return to be received before continuing.
dbus_call_async
Requests that a method call be performed a-synchronously, returning a pending call object, which will collect the reply when it eventually arrives.
dbus_call_noreply
Requests that a method call be performed a-synchronously, discarding any possible reply or error message.
dbus_call_timeout
Indicates that the next parameter for the method call will specify the time to wait for a reply in milliseconds. If omitted, then the default timeout for the object will be used
