Efl.Net.Socket.Udp (class)


A base UDP socket.

This is the common class and takes an existing FD, usually created by an dialer.

Since for the server 'clients' there is no accepted connection it will reuse the same file decriptor. To avoid it being closed, another class Efl.Net.Server.Udp.Client is used instead.

Since 1.19

closed Notifies closed, when property is marked as true
can_read,changed Notifies can_read property changed.
eos Notifies end of stream, when property is marked as true.
can_write,changed Notifies can_write property changed.
error Called when a error occurred on the file descriptor
read Called when a read happened on the file descriptor
write Called when a write happened on the file descriptor
callback,add A callback was added.
callback,del A callback was deleted.
del Object is being deleted.
destruct Object has been fully destroyed. It can not be used beyond this point. This event should only serve to clean up any dangling pointer.
