- org.rrd4j.core.jrrd.RRDFile

All Implemented Interfaces:
Constants
```
class RRDFile
extends Object
implements Constants
```
This class is used read information from an RRD file. Writing to RRD files is not currently supported. It uses NIO's RandomAccessFile to read the file
Currently this can read RRD files that were generated on Solaris (Sparc) and Linux (x86).
