ImageInputStreamImpl2 (Silverpeas Core 6.4 API)

java.lang.Object
- javax.imageio.stream.ImageInputStreamImpl
- - org.monte.media.io.ImageInputStreamImpl2

All Implemented Interfaces:

Closeable, DataInput, AutoCloseable, ImageInputStream

Direct Known Subclasses:

ByteArrayImageInputStream
```
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 Detail
  - 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.
