		<method name="get_local_port" qualifiers="const">
			<return type="int" />
			<description>
				Returns the local port this server is listening to.
			</description>
		</method>
		<method name="is_connection_available" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if a connection is available for taking.
			</description>
		</method>
		<method name="is_listening" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the server is currently listening for connections.

			<description>
				Listen on the [code]port[/code] binding to [code]bind_address[/code].
				If [code]bind_address[/code] is set as [code]"*"[/code] (default), the server will listen on all available addresses (both IPv4 and IPv6).
				If [code]bind_address[/code] is set as [code]"0.0.0.0"[/code] (for IPv4) or [code]"::"[/code] (for IPv6), the server will listen on all available addresses matching that IP type.
				If [code]bind_address[/code] is set to any valid address (e.g. [code]"192.168.1.101"[/code], [code]"::1"[/code], etc), the server will only listen on the interface with that addresses (or fail if no interface with the given address exists).
