Class ImageInputStreamImpl2

java.lang.Object

javax.imageio.stream.ImageInputStreamImpl

org.monte.media.io.ImageInputStreamImpl2

All Implemented Interfaces:

Closeable, DataInput, AutoCloseable, ImageInputStream

Direct Known Subclasses:

ByteArrayImageInputStream, FilterImageInputStream, SubImageInputStream, UncachedImageInputStream

public abstract class ImageInputStreamImpl2
extends ImageInputStreamImpl

ImageInputStreamImpl2 fixes bugs in ImageInputStreamImpl.

ImageInputStreamImpl uses read(byte[]) instead of readFully(byte[]) inside of readShort. This results in corrupt data input if the underlying stream can not fulfill the read operation in a single step.

Field Details

byteBuf

protected byte[] byteBuf

Byte buffer used for readFully(type[], int, int). Note that this array is also used for bulk reads in readShort(), readInt(), etc, so it should be large enough to hold a primitive value (i.e. >= 8 bytes). Also note that this array is package protected, so that it can be used by ImageOutputStreamImpl in a similar manner.
