Class Summary

Class	Description
AbstractFileIOChannel
AsynchronousBlockReader	A reader that reads data in blocks from a file channel.
AsynchronousBlockWriter
AsynchronousBlockWriterWithCallback	An asynchronous implementation of the BlockChannelWriterWithCallback that queues I/O requests and calls a callback once they have been handled.
AsynchronousBufferFileReader
AsynchronousBufferFileSegmentReader
AsynchronousBufferFileWriter
AsynchronousBulkBlockReader
AsynchronousFileIOChannel<T,R extends org.apache.flink.runtime.io.disk.iomanager.IORequest>	A base class for readers and writers that accept read or write requests for whole blocks.
ChannelReaderInputView	A DataInputView that is backed by a BlockChannelReader, making it effectively a data input stream.
ChannelWriterOutputView	A DataOutputView that is backed by a BlockChannelWriter, making it effectively a data output stream.
FileIOChannel.Enumerator	An enumerator for channels that logically belong together.
FileIOChannel.ID	An ID identifying an underlying file channel.
FileSegment
HeaderlessChannelReaderInputView	A DataInputView that is backed by a BlockChannelReader, making it effectively a data input stream.
IOManager	The facade for the provided I/O manager services.
IOManagerAsync	A version of the IOManager that uses asynchronous I/O.
QueuingCallback<T>	A RequestDoneCallback that adds the memory segments to a blocking queue.
RequestQueue<E>	A LinkedBlockingQueue that is extended with closing methods.
SynchronousBufferFileReader	A synchronous BufferFileReader implementation.
SynchronousFileIOChannel	A base class for synchronous readers and writers.
