DefaultImageSessionContext (org.apache.xmlgraphics:xmlgraphics-commons 2.7 API)

java.lang.Object
- org.apache.xmlgraphics.image.loader.impl.AbstractImageSessionContext
- - org.apache.xmlgraphics.image.loader.impl.DefaultImageSessionContext

All Implemented Interfaces:

ImageSessionContext
```
public class DefaultImageSessionContext
extends AbstractImageSessionContext
```
Very simple implementation of the ImageSessionContext interface. It works for absolute URLs and local filenames only. Consider writing your own implementation of the ImageSessionContext if you need more sophisticated functionality.
