Class Summary

Class	Description
Base64	Encodes and decodes to and from Base64 notation.
Base64.Base64InputStream	A Base64.Base64InputStream will read data from another InputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
ByteBufferUtils	Utility functions for working with byte buffers, such as reading/writing variable-length long numbers.
ByteRangeUtils	Utility methods for working with ByteRange.
Bytes	Utility class that handles byte arrays, conversions to/from other types, comparisons, hash code generation, manufacturing keys for HashMaps or HashSets, etc.
Bytes.ByteArrayComparator	Byte array comparator class.
Bytes.RowEndKeyComparator	A Bytes.ByteArrayComparator that treats the empty array as the largest value.
CompressionTest	Compression validation test.
Hash	This class represents a common API for hashing functions.

Merge	Utility that can merge any two regions in the same table: adjacent, overlapping or disjoint.
MurmurHash	This is a very fast, non-cryptographic hash suitable for general hash-based lookup.
OrderedBytes	Utility class that handles ordered byte arrays.
Pair<T1,T2>	A generic class for pairs.
PairOfSameType<T>	A generic, immutable class for pairs of objects both of type T.
PrettyPrinter
SimpleByteRange	A basic ByteRange implementation.
SimplePositionedByteRange	Extends the basic SimpleByteRange implementation with position support.
