HasValueReceiver< T > Class Template Reference

#include <valuereceiver.h>

Detailed Description

template<typename T>
class maxon::HasValueReceiver< T >

ValueReceiver type that will verify if one value was received from the caller. No information about the actual value collected will be retained, just found/not found. Useful for calls such as GetConnections when we are interested if there is at least one/any of connection of the given type. Iterations stop after a value is found.

String myString;
...
HasValueReceiver<const String&> recv;
myString.Split('a', false, recv) iferr_return;
if (recv.IsPopulated())
DiagnosticOutput("At least one value was found");
