/** @page components_transportmanager_internal_design_transport_adapters_tcp_adapter TCP Adapter
 *
 * TCP adapter handles communication with remote devices via TCP/IP socket. It is implemented in
 * NsSmartDeviceLink::NsTransportManager::CTCPAdapter.
 *
 * @section components_transportmanager_internal_design_transport_adapters_tcp_adapter_listen Listening for connections
 *
 * TCP adapter creates listening TCP socket (TCP port is specified in NsSmartDeviceLink::NsTransportManager::CTCPAdapter::cTCPAdapterPort)
 * and listens for incoming connections. Devices are identified by their IP address.
 *
 * @section components_transportmanager_internal_design_transport_adapters_tcp_adapter_accept Accepting connection
 *
 * When TCP adapter accepts connection it checks if there is a device with IP address matching with IP address of accepted connection.
 * If there is no such device, then this device is added and device list is updated.
 *
 * @section components_transportmanager_internal_design_transport_adapters_tcp_adapter_disconnecting Disconnecting
 *
 * When socket gets disconnected TCP adapter checks if there is another opened connection for IP address of disconnected application.
 * If it was the last application from this IP address then device with this IP address is removed and devices list is updated.
