Class CustomConcurrentHashMap.Segment

java.lang.Object

java.util.concurrent.locks.ReentrantLock

groovyx.gpars.extra166y.CustomConcurrentHashMap.Segment

All Implemented Interfaces:

java.io.Serializable, java.util.concurrent.locks.Lock

Enclosing class:

CustomConcurrentHashMap<K,V>

static final class CustomConcurrentHashMap.Segment
extends java.util.concurrent.locks.ReentrantLock

Each Segment holds a count and table corresponding to a segment of the table. This class contains only those methods for directly assigning these fields, which must only be called while holding locks.
