CellScannable	Implementer can return a CellScanner over its Cell content.
CellScanner	An interface for iterating through a sequence of cells.
ExtendedCell	Extension to Cell with server side required functions.
KeyValue.SamePrefixComparator<T>	Avoids redundant comparisons for better performance.
Service	Simple Service.

Class Summary

Class	Description
ArrayBackedTag	This is a Tag implementation in which value is backed by an on heap byte array.
AsyncConsoleAppender	Logger class that buffers before trying to log to the specified console.
AuthUtil	Utility methods for helping with security tasks.
BaseConfigurable	HBase version of Hadoop's Configured class that doesn't initialize the configuration via BaseConfigurable.setConf(Configuration) in the constructor, but only sets the configuration through the BaseConfigurable.setConf(Configuration) method
ByteBufferCell	This class is a server side extension to the Cell interface.
ByteBufferKeyOnlyKeyValue	This is a key only Cell implementation which is identical to KeyValue.KeyOnlyKeyValue with respect to key serialization but have its data in the form of Byte buffer (onheap and offheap).
ByteBufferKeyValue	This Cell is an implementation of ByteBufferCell where the data resides in off heap/ on heap ByteBuffer
ByteBufferTag	This is a Tag implementation in which value is backed by ByteBuffer
CellComparator	Compare two HBase cells.
CellComparator.MetaCellComparator	A CellComparator for hbase:meta catalog table KeyValues.
CellComparator.RowComparator	Comparator that compares row component only of a Cell
CellUtil	Utility methods helpful slinging Cell instances.
ChoreService	ChoreService is a service that can be used to schedule instances of ScheduledChore to run periodically while sharing threads.
CompoundConfiguration	Do a shallow merge of multiple KV configuration pools.
HBaseConfiguration	Adds HBase configuration files to a Configuration
HBaseInterfaceAudience	This class defines constants for different classes of hbase limited private apis
HConstants	HConstants holds a bunch of HBase-related constants
IndividualBytesFieldCell
JitterScheduledThreadPoolExecutorImpl	ScheduledThreadPoolExecutor that will add some jitter to the RunnableScheduledFuture.getDelay.
KeyValue	An HBase Key/Value.
KeyValue.KeyOnlyKeyValue	A simple form of KeyValue that creates a keyvalue with only the key part of the byte[] Mainly used in places where we need to compare two cells.
KeyValue.KVComparator	Deprecated : Use CellComparator.
KeyValue.MetaComparator	Deprecated : CellComparator.META_COMPARATOR to be used
KeyValue.RawBytesComparator	Deprecated Not to be used for any comparsions
KeyValue.RowOnlyComparator	Comparator that compares row component only of a KeyValue.
KeyValueTestUtil
KeyValueUtil	static convenience methods for dealing with KeyValues and collections of KeyValues
NamespaceDescriptor	Namespace POJO class.
NamespaceDescriptor.Builder
NoTagsByteBufferKeyValue	An extension of the ByteBufferKeyValue where the tags length is always 0
NoTagsKeyValue	An extension of the KeyValue where the tags length is always 0
ProcedureInfo	Procedure information
ScheduledChore	ScheduledChore is a task performed on a period in hbase.
ServerName	Name of a particular incarnation of an HBase Server.
SizeCachedKeyValue	This class is an extension to KeyValue where rowLen and keyLen are cached.
SizeCachedNoTagsKeyValue	This class is an extension to ContentSizeCachedKeyValue where there are no tags in Cell.
TableName	Immutable POJO class for representing a table name.
TagType
TagUtil

Annotation Types Summary

Annotation Type	Description
MetaMutationAnnotation	The field or the parameter to which this annotation can be applied only when it holds mutations for hbase:meta table.
