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 character 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
@deprecated Use {@link #socketTextStream(String, int, String, long)} instead. | [
