Examples of ProtocolBindingProvider

org.openhab.binding.tcp.protocol.ProtocolBindingProvider
Further specialisation of the ChannelBindingProvider interface that serves as base for the "default" ASCII based TCP and UDP network bindings In all of the defined methods below, "ProtocolCommand" is the 'command' to be executed by the protocol, which is mapped on a openHAB Command through the binding configuration. See TCP and UDP implementations. In a lot of protocols the ProtocolCommand will just be a (data)string that is sent "as is" to the remote-end @author Karel Goderis @since 1.1.0
