Package jline.lang.nodeparam

Class CacheNodeParam

java.lang.Object

jline.lang.NodeParam

jline.lang.nodeparam.CacheNodeParam

All Implemented Interfaces:

Serializable

public class CacheNodeParam
extends NodeParam

Parameter container for cache nodes in queueing networks.

This class encapsulates all the parameters needed to configure a cache node, including cache capacity, item costs, hit/miss class mappings, replacement strategies, and access probabilities. Cache nodes model caching systems where items can be stored temporarily to reduce access latencies.

Key cache characteristics managed by this class:

• Item capacity constraints and access costs
• Hit and miss class routing for cache hits/misses
• Replacement strategies (LRU, FIFO, etc.) when cache is full
• Read access probabilities for different items
• Actual hit/miss probabilities for performance analysis

Since:

1.0
