Uses of ByteBufferAllocator in org.apache.parquet.bytes

Classes in org.apache.parquet.bytes that implement ByteBufferAllocator

Modifier and Type	Class and Description
class	DirectByteBufferAllocator
class	HeapByteBufferAllocator
class	ReusingByteBufferAllocator A special ByteBufferAllocator implementation that keeps one ByteBuffer object and reuses it at the next ReusingByteBufferAllocator.allocate(int) call.
class	TrackingByteBufferAllocator A wrapper ByteBufferAllocator implementation that tracks whether all allocated buffers are released.

Methods in org.apache.parquet.bytes with parameters of type ByteBufferAllocator

Modifier and Type	Method and Description
BytesInput	BytesInput.copy(ByteBufferAllocator allocator, Consumer<ByteBuffer> callback) Copies the content of this BytesInput object to a newly created ByteBuffer and returns it wrapped in a BytesInput object.
static ReusingByteBufferAllocator	ReusingByteBufferAllocator.strict(ByteBufferAllocator allocator) Creates a new strict ReusingByteBufferAllocator object with the specified "parent" allocator to be used for allocating/releasing the one buffer.
ByteBuffer	BytesInput.toByteBuffer(ByteBufferAllocator allocator, Consumer<ByteBuffer> callback) Returns a ByteBuffer object referencing the data behind this BytesInput object.
static ReusingByteBufferAllocator	ReusingByteBufferAllocator.unsafe(ByteBufferAllocator allocator) Creates a new unsafe ReusingByteBufferAllocator object with the specified "parent" allocator to be used for allocating/releasing the one buffer.
static CapacityByteArrayOutputStream	CapacityByteArrayOutputStream.withTargetNumSlabs(int minSlabSize, int maxCapacityHint, int targetNumSlabs, ByteBufferAllocator allocator) Construct a CapacityByteArrayOutputStream configured such that its initial slab size is determined by CapacityByteArrayOutputStream.initialSlabSizeHeuristic(int, int, int), with targetCapacity == maxCapacityHint
static TrackingByteBufferAllocator	TrackingByteBufferAllocator.wrap(ByteBufferAllocator allocator)

Constructors in org.apache.parquet.bytes with parameters of type ByteBufferAllocator

Constructor and Description
ByteBufferReleaser(ByteBufferAllocator allocator) Constructs a new ByteBufferReleaser instance with the specified ByteBufferAllocator to be used for releasing the buffers in ByteBufferReleaser.close().
CapacityByteArrayOutputStream(int initialSlabSize, ByteBufferAllocator allocator) Deprecated. use CapacityByteArrayOutputStream(int, int, ByteBufferAllocator)
CapacityByteArrayOutputStream(int initialSlabSize, int maxCapacityHint, ByteBufferAllocator allocator)
ConcatenatingByteBufferCollector(ByteBufferAllocator allocator) Constructs a new ConcatenatingByteBufferCollector instance with the specified allocator.

Methods in org.apache.parquet.io with parameters of type ByteBufferAllocator

Modifier and Type	Method and Description
void	SeekableInputStream.readVectored(List<ParquetFileRange> ranges, ByteBufferAllocator allocator) Read a set of disjoint file ranges in a vectored manner.
boolean	SeekableInputStream.readVectoredAvailable(ByteBufferAllocator allocator) Is the SeekableInputStream.readVectored(List, ByteBufferAllocator) method available?
