groovyx.gpars.extra166y
[Java] Class CustomConcurrentHashMap.Segment

java.lang.Object
  java.util.concurrent.locks.ReentrantLock
      groovyx.gpars.extra166y.CustomConcurrentHashMap.Segment

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.

Field Summary
int count

Node[] table

 
Constructor Summary
CustomConcurrentHashMap.Segment()

 
Method Summary
void clearCount()

void decrementCount()

Node[] getTableForAdd(CustomConcurrentHashMap cchm)

Node[] getTableForTraversal()

void incrementCount()

Node[] resizeTable(CustomConcurrentHashMap cchm)

See the similar code in ConcurrentHashMap for explanation.
