I'm not a java developer, but I want to fix the only warning in my project in this part of code:
public abstract class SelectorThread<T extends MMOConnection<T, RP, SP>, RP extends ReceivablePacket<T, RP, SP>, SP extends SendablePacket<T, RP, SP>>
{
protected static final Log _log = new MMOLogger(SelectorThread.class, 1000);
private final AcceptorThread<T, RP, SP> _acceptorThread;
private final ReadWriteThread<T, RP, SP>[] _readWriteThreads;
protected SelectorThread(SelectorConfig sc, IPacketHandler<T, RP, SP> packetHandler) throws IOException
{
_acceptorThread = new AcceptorThread<T, RP, SP>("AcceptorThread", this, sc);
_readWriteThreads = new ReadWriteThread[sc.getSelectorThreadCount()];
for (int i = 0; i < _readWriteThreads.length; i++)
_readWriteThreads[i] = new ReadWriteThread<T, RP, SP>("ReadWriteThread-" + (i + 1), this, sc, packetHandler);
}
...
}
The warning:
Type safety: The expression of type ReadWriteThread[] needs unchecked
conversion to conform to ReadWriteThread<T,RP,SP>[]
Please, can someone help me fix this, or tell me what I must know to fix this. I understand that line above is fixed by <T, RP, SP>, but this doesn't work with array.
Upd: I see that my question is duplicate and my problem is: this is not safe to use generics in arrays. But how do I need to change my code to fix this? All I came up is
_readWriteThreads = (ReadWriteThread<T, RP, SP>[]) Array.newInstance(ReadWriteThread.class, sc.getSelectorThreadCount());
But this code also gave me a warning.
