Packages that use RefCnt

Package	Description
org.apache.hadoop.hbase.io.hfile.bucket	Provides BucketCache, an implementation of BlockCache.
org.apache.hadoop.hbase.nio
org.apache.hadoop.hbase.regionserver

Uses of RefCnt in org.apache.hadoop.hbase.io.hfile.bucket

Fields in org.apache.hadoop.hbase.io.hfile.bucket declared as RefCnt

Modifier and Type	Field and Description
private RefCnt	BucketEntry.refCnt The RefCnt means how many paths are referring the BucketEntry, there are two cases: 1.If the IOEngine.usesSharedMemory() is false(eg.FileIOEngine),the refCnt is always 1 until this BucketEntry is evicted from BucketCache.backingMap.Even if the corresponding HFileBlock is referenced by RPC reading, the refCnt should not increase.

Uses of RefCnt in org.apache.hadoop.hbase.nio

Fields in org.apache.hadoop.hbase.nio declared as RefCnt

Modifier and Type	Field and Description
protected RefCnt	ByteBuff.refCnt

Fields in org.apache.hadoop.hbase.nio with type parameters of type RefCnt

Modifier and Type	Field and Description
private static org.apache.hbase.thirdparty.io.netty.util.ResourceLeakDetector<RefCnt>	RefCnt.detector
private org.apache.hbase.thirdparty.io.netty.util.ResourceLeakTracker<RefCnt>	RefCnt.leak

Methods in org.apache.hadoop.hbase.nio that return RefCnt

Modifier and Type	Method and Description
static RefCnt	RefCnt.create() Create an RefCnt with an initial reference count = 1.
static RefCnt	RefCnt.create(ByteBuffAllocator.Recycler recycler)
RefCnt	ByteBuff.getRefCnt()
RefCnt	RefCnt.touch()

Methods in org.apache.hadoop.hbase.nio with parameters of type RefCnt

Modifier and Type	Method and Description
static ByteBuff	ByteBuff.wrap(ByteBuffer[] buffers, RefCnt refCnt) In theory, the upstream should never construct an ByteBuff by passing an given refCnt, so please don't use this public method in other place.
private static ByteBuff	ByteBuff.wrap(ByteBuffer buffer, RefCnt refCnt)
private static ByteBuff	ByteBuff.wrap(List<ByteBuffer> buffers, RefCnt refCnt)

Constructors in org.apache.hadoop.hbase.nio with parameters of type RefCnt

Constructor and Description
MultiByteBuff(RefCnt refCnt, ByteBuffer... items)
MultiByteBuff(RefCnt refCnt, ByteBuffer[] items, int[] itemBeginPos, int limit, int limitedIndex, int curItemIndex, int markedIndex)
SingleByteBuff(RefCnt refCnt, ByteBuffer buf)

Uses of RefCnt in org.apache.hadoop.hbase.regionserver

Fields in org.apache.hadoop.hbase.regionserver declared as RefCnt

Modifier and Type	Field and Description
private RefCnt	ImmutableMemStoreLAB.refCnt
private RefCnt	MemStoreLABImpl.refCnt Its initial value is 1, so it is one bigger than the current count of open scanners which reading data from this MemStoreLAB.
