"SocketTextStreamFunction"... | Creates a new data stream that contains the strings received infinitely from a socket. Received strings are
decoded by the system's default character set. On the termination of the socket server connection retries can be
initiated.
<p>Let us note that the socket itself does not report on abort and as a consequence retries are only initiated when
the socket was gracefully terminated.
@param hostname
The host name which a server socket binds
@param port
The port number which a server socket binds. A port number of 0 means that the port number is automatically
allocated.
@param delimiter
A string which splits received strings into records
@param maxRetry
The maximal retry interval in seconds while the program waits for a socket that is temporarily down.
Reconnection is initiated every second. A number of 0 means that the reader is immediately terminated,
while
a negative value ensures retrying forever.
@return A data stream containing the strings received from the socket | [

... | Creates an InstrumentedExecutor that uses a single worker thread operating
off an unbounded queue. (Note however that if this single
thread terminates due to a failure during execution prior to
shutdown, a new one will take its place if needed to execute
subsequent tasks.) Tasks are guaranteed to execute
sequentially, and no more than one task will be active at any
given time. Unlike the otherwise equivalent
{@code newFixedThreadPool(1)} the returned executor is
guaranteed not to be reconfigurable to use additional threads.
@param registry the {@link MetricRegistry} that will contain the metrics.
@param name the (metrics) name for this executor service, see {@link MetricRegistry#name(String, String...)}.
@return the newly created single-threaded Executor

It is safe to add arguments modified by other methods in this class (such as
