## Uses of Class
org.apache.lucene.store.DataOutput

Packages that use DataOutput
org.apache.lucene.store: Binary i/o API, used for all index data.
org.apache.lucene.util: Some utility classes.
org.apache.lucene.util.fst: Finite state transducers
org.apache.lucene.util.packed: The packed package provides random access capable arrays of positive longs.

Uses of DataOutput in org.apache.lucene.store

Subclasses of DataOutput in org.apache.lucene.store
`class` `BufferedIndexOutput` Base implementation class for buffered `IndexOutput`.
`class` `ByteArrayDataOutput` DataOutput backed by a byte array.
`class` `ChecksumIndexOutput` Writes bytes through to a primary IndexOutput, computing checksum.
`protected static class` `FSDirectory.FSIndexOutput`
`class` `IndexOutput` Abstract base class for output to a file in a Directory.
`class` `MockIndexOutputWrapper` Used by MockRAMDirectory to create an output stream that will throw an IOException on fake disk full, track max disk space actually used, and maybe throw random IOExceptions.
`class` `OutputStreamDataOutput` A `DataOutput` wrapping a plain `OutputStream`.
`class` `RAMOutputStream` A memory-resident `IndexOutput` implementation.
