Package io.deephaven.io.streams

Class ByteBufferInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.DataInput, java.lang.AutoCloseable
    public class ByteBufferInputStream
extends java.io.InputStream
implements java.io.DataInput
    This is an InputStream implementation which reads from a java.nio.ByteBuffer. If a read operation crosses the end of the buffer, the BufferUnderflowException is converted to an EOFException. The stream contains no state other than that in in the buffer itself, so the buffer can be exchanged at will with the setBuffer() method.
