/**
 * Defines all the flags available in the Hot Rod client that can influence the behavior of operations.
 * <p />
 * Available flags:
 * <ul>
 *    <li>{@link #FORCE_RETURN_VALUE} - By default, previously existing values for {@link Map} operations are not
 *                                      returned. E.g. {@link RemoteCache#put(Object, Object)} does <i>not</i> return
 *                                      the previous value associated with the key.  By applying this flag, this default
 *                                      behavior is overridden for the scope of a single invocation, and the previous
 *                                      existing value is returned.</li>
 *    <li>{@link #DEFAULT_LIFESPAN}     This flag can either be used as a request flag during a put operation to mean
 *                                      that the default server lifespan should be applied or as a response flag meaning that
 *                                      the return entry has a default lifespan value</li>
 *    <li>{@link #DEFAULT_MAXIDLE}      This flag can either be used as a request flag during a put operation to mean
 *                                      that the default server maxIdle should be applied or as a response flag meaning that
 *                                      the return entry has a default maxIdle value</li>
