IndexInput.ReadBytes Method (Byte[], Int32, Int32, Boolean)

Reads a specified number of bytes into an array at the specified offset with control over whether the read should be buffered (callers who have their own buffer should pass in "false" for useBuffer). Currently only {@link BufferedIndexInput} respects this parameter.

public virtual void ReadBytes(
   byte[] b,
   int offset,
   int len,
   bool useBuffer
);
