Class BufferedImageInputStream

java.lang.Object
  javax.imageio.stream.ImageInputStreamImpl
      com.twelvemonkeys.imageio.stream.BufferedImageInputStream

All Implemented Interfaces:

DataInput, ImageInputStream

public final class BufferedImageInputStream
extends ImageInputStreamImpl
implements ImageInputStream

A buffered ImageInputStream. Experimental - seems to be effective for FileImageInputStream and FileCacheImageInputStream when doing a lot of single-byte reads (or short byte-array reads) on OS X at least. Code that uses the readFully methods are not affected by the issue.
