org.apache.hadoop.fs	An abstract file system API.
org.apache.hadoop.fs.impl	This package contains implementation classes for use inside filesystems.
org.apache.hadoop.io	Generic i/o code for use when reading and writing data to the network, to databases, and to files.

Uses of ByteBufferPool in org.apache.hadoop.crypto

Methods in org.apache.hadoop.crypto with parameters of type ByteBufferPool

Modifier and Type	Method	Description
ByteBuffer	CryptoInputStream.read(ByteBufferPool bufferPool, int maxLength, EnumSet<ReadOption> opts)

Uses of ByteBufferPool in org.apache.hadoop.fs

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

Modifier and Type	Method	Description
static ByteBuffer	ByteBufferUtil.fallbackRead(InputStream stream, ByteBufferPool bufferPool, int maxLength)	Perform a fallback read.
final ByteBuffer	FSDataInputStream.read(ByteBufferPool bufferPool, int maxLength)
ByteBuffer	FSDataInputStream.read(ByteBufferPool bufferPool, int maxLength, EnumSet<ReadOption> opts)
ByteBuffer	HasEnhancedByteBufferAccess.read(ByteBufferPool factory, int maxLength, EnumSet<ReadOption> opts)	Get a ByteBuffer containing file data.

Uses of ByteBufferPool in org.apache.hadoop.fs.impl

Classes in org.apache.hadoop.fs.impl that implement ByteBufferPool

Modifier and Type	Class	Description
final class	TrackingByteBufferPool	A wrapper ByteBufferPool implementation that tracks whether all allocated buffers are released.
final class	VectorIOBufferPool	A ByteBufferPool implementation that uses a pair of functions to allocate and release ByteBuffers; intended for use implementing the VectorIO API as it makes the pair of functions easier to pass around and use in existing code.

Methods in org.apache.hadoop.fs.impl with parameters of type ByteBufferPool

Modifier and Type	Method	Description
static TrackingByteBufferPool	TrackingByteBufferPool.wrap(ByteBufferPool allocator)	Wrap an existing allocator with this tracking allocator.

Uses of ByteBufferPool in org.apache.hadoop.io

Classes in org.apache.hadoop.io that implement ByteBufferPool

Modifier and Type	Class	Description
class	ElasticByteBufferPool	This is a simple ByteBufferPool which just creates ByteBuffers as needed.
final class	WeakReferencedElasticByteBufferPool	Buffer pool implementation which uses weak references to store buffers in the pool, such that they are garbage collected when there are no references to the buffer during a gc run.
