Package org.apache.hadoop.hbase.util

Interface Summary
MetaUtils.ScannerListener Used by scanRootRegion and scanMetaRegion to call back the caller so it can process the data for a row.
 

Class Summary
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.
Base64.Base64OutputStream A Base64.Base64OutputStream will write data to another OutputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
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.
ClassSize Class for determining the "size" of a class, an attempt to calculate the actual bytes that an object of this class will occupy in memory The core of this class is taken from the Derby project
