Uses of PositionedReadable in org.apache.hadoop.fs

Classes in org.apache.hadoop.fs that implement PositionedReadable

Modifier and Type	Class	Description
class	BufferedFSInputStream	A class that optimizes reading from FSInputStream by buffering.
class	FSDataInputStream	Utility that wraps a FSInputStream in a DataInputStream and buffers input through a BufferedInputStream.
class	FSInputChecker	This is a generic input stream for verifying checksums for data before it is read by a user.
class	FSInputStream	FSInputStream is a generic old InputStream with a little bit of RAF-style seek ability.

Methods in org.apache.hadoop.fs with parameters of type PositionedReadable

Modifier and Type	Method	Description
static CompletableFuture<ByteBuffer>	VectoredReadUtils.readRangeFrom(PositionedReadable stream, FileRange range, IntFunction<ByteBuffer> allocate)	Synchronously reads a range from the stream dealing with the combinations of ByteBuffers buffers and PositionedReadable streams.
static CompletableFuture<ByteBuffer>	VectoredReadUtils.readRangeFrom(PositionedReadable stream, FileRange range, IntFunction<ByteBuffer> allocate, Consumer<ByteBuffer> release)	Synchronously reads a range from the stream dealing with the combinations of ByteBuffers buffers and PositionedReadable streams.
static void	VectoredReadUtils.readVectored(PositionedReadable stream, List<? extends FileRange> ranges, IntFunction<ByteBuffer> allocate)	This is the default implementation which iterates through the ranges to read each synchronously, but the intent is that subclasses can make more efficient readers.
static void	VectoredReadUtils.readVectored(PositionedReadable stream, List<? extends FileRange> ranges, IntFunction<ByteBuffer> allocate, Consumer<ByteBuffer> release)	Variant of VectoredReadUtils.readVectored(PositionedReadable, List, IntFunction) where a release() function is invoked if problems surface during reads.
