ClassDescriptionOur own implementation of ByteArrayOutputStream where all methods are NOT synchronized and supports writing ByteBuffer directly to it.ByteBuffAllocator is a nio ByteBuffer pool.Not thread safe!An OutputStream which writes data into ByteBuffers.Not thread safe!This interface marks a class to support writing ByteBuffers into it.Our extension of DataOutputStream which implements ByteBufferWriterWhen deal with OutputStream which is not ByteBufferWriter type, wrap it with this class.Not thread safe!Accepts a stream of Cells.A ByteBuffAllocator that rewrite the bytebuffers right after released.An input stream that delegates all operations to another input stream.Instances of this class can be used to watch a directory for file changes.The FileLink is a sort of hardlink, that allows access to a file given a set of locations.FileLink InputStream that handles the switch between the original path and the alternative locations, when the file is moved.Wrapper for input stream(s) that takes care of the interaction of FS and HBase checksums, as well as closing streams.A facade for a
HFile.Readerthat serves up either the top or bottom half of a HFile where 'bottom' is the first half of the file containing the keys that sort lowest and 'top' is the second half of the file with keys that sort greater than those of the bottom half.Implementations can be asked for an estimate of their size in bytes.HFileLink describes a link to an hfile.A byte sequence that is usable as a key or value.A Comparator optimized for ImmutableBytesWritable.A reference to the top or bottom half of a store file where 'bottom' is the first half of the file containing the keys that sort lowest and 'top' is the second half of the file with keys that sort greater than those of the bottom half.For split HStoreFiles, it specifies if the file covers the lower half or the upper half of the key rangeA CellScanner that knows its size in memory in bytes.Context that holds the dictionary for Tag compression and doing the compress/uncompress.Represents an interval of version timestamps.WALLink describes a link to a WAL.An optional interface to 'size' writables.
