类 SynchronousBufferFileReader

java.lang.Object

org.apache.flink.runtime.io.disk.iomanager.AbstractFileIOChannel

org.apache.flink.runtime.io.disk.iomanager.SynchronousFileIOChannel

org.apache.flink.runtime.io.disk.iomanager.SynchronousBufferFileReader

所有已实现的接口:

BufferFileReader, FileIOChannel

public class SynchronousBufferFileReader
extends SynchronousFileIOChannel
implements BufferFileReader

A synchronous BufferFileReader implementation.

This currently bypasses the I/O manager as it is the only synchronous implementation, which is currently in use.

TODO Refactor I/O manager setup and refactor this into it
