Example 1 with Channel

use of org.spongepowered.api.network.channel.Channel in project SpongeCommon by SpongePowered.

the class SpongeChannelManager method ofType.

@Override

        if (!channelType.isInstance(binding)) {
            throw new IllegalStateException("There's already a channel registered for " + channelKey + ", but it is not of the requested type " + channelType);
        }
        return (C) binding;
