Example 29 with Protocol

use of org.jgroups.stack.Protocol in project JGroups by belaban.

the class FORK method createForkStack.

/**
 * Returns the fork stack for fork_stack_id (if exitstent), or creates a new fork-stack from protocols and adds it
 * into the hashmap of fork-stack (key is fork_stack_id).
 * Method init() will be called on each protocol, from bottom to top.
 * @param fork_stack_id The key under which the new fork-stack should be added to the fork-stacks hashmap
 * @param protocols A list of protocols from <em>bottom to top</em> to be inserted. They will be sandwiched
 *                  between ForkProtocolStack (top) and ForkProtocol (bottom). The list can be empty (or null) in
 *                  which case we won't create any protocols, but still have a separate fork-stack inserted.
 * @param initialize If false, the ref count 'inits' will not get incremented and init() won't be called. This is
 *                   needed when creating a fork stack from an XML config inside of the FORK protocol. The protocols
 *                   in the fork stack will only get initialized on the first ForkChannel creation
 * @return The new {@link ForkProtocolStack}, or the existing stack (if present)
