Example 49 with Inet6Address

use of java.net.Inet6Address in project JGroups by belaban.

the class Configurator method setupProtocolStack.

/**
 * The configuration string has a number of entries, separated by a ':' (colon).
 * Each entry consists of the name of the protocol, followed by an optional configuration
 * of that protocol. The configuration is enclosed in parentheses, and contains entries
 * which are name/value pairs connected with an assignment sign (=) and separated by
 * a semicolon.
 * <pre>UDP(in_port=5555;out_port=4445):FRAG(frag_size=1024)</pre><p>
 * The <em>first</em> entry defines the <em>bottommost</em> layer, the string is parsed
 * left to right and the protocol stack constructed bottom up. Example: the string
 * "UDP(in_port=5555):FRAG(frag_size=32000):DEBUG" results is the following stack:<pre>
 *
 *   -----------------------
 *  | DEBUG                 |
 *  |-----------------------|
 *  | FRAG frag_size=32000  |
 *  |-----------------------|
 *  | UDP in_port=32000     |
