org.apache.arrow.vector.ipc.WriteChannel

すべての実装されたインタフェース:

AutoCloseable

public class WriteChannel
extends Object
implements AutoCloseable

Wrapper around a WritableByteChannel that maintains the position as well adding some common serialization utilities. All write methods in this class follow full write semantics, i.e., write calls only return after requested data has been fully written. Note this is different from java WritableByteChannel interface where partial write is allowed
