Hi all,
suppose I have a class that can take callbacks to invoke them in case of any
event:
public signal void DataReceived(uint8 byte);
//...
DataReceived(byte);
...and I have a client that registers its handler to it:
someInstance.DataReceived.connect(OnDataReceived);
//...
private void OnDataReceived(uint8 byte)
{
//do something.
}
..how can I check if my handler was registered already to avoid it from being
registered a several times?
I'd like to do something like this:
if( !someInstance.DataReceived.handler_is_connected(OnDataReceived) )
{
someInstance.DataReceived.connect(OnDataReceived);
}
Thanks in advance for any hint.
gilzad
