Class JoinNodeParam

java.lang.Object

jline.lang.NodeParam

jline.lang.nodeparam.JoinNodeParam

All Implemented Interfaces:

Serializable

public class JoinNodeParam
extends NodeParam

Parameter container for join nodes in queueing networks.

This class configures join nodes that synchronize parallel tasks back into single jobs. Join nodes are the complement to fork nodes in fork-join queueing models, handling task completion synchronization and job reconstruction.

Join node capabilities:

• Task synchronization with various join strategies
• Configurable fan-in ratios per job class
• Required task completion thresholds
• Class-specific joining policies

Common join strategies include waiting for all tasks, partial synchronization, or quorum-based completion policies.
