| Detector | | public class Detector (Code) | | A Detector stores one entry from the magic.xml file, and contains
the functionality to determines if a certain byte[] satisfies it.
Implementation made on the basis of actual magic file and its manual.
TODO:
- link the info with mimetypes
- add test modifiers
- add commandline switches for warning, error and debugging messages
Ignored features of magic:
- date types
- indirect offsets (prefix of '&' in sublevel match or (address+bytes) where offset = value of address plus bytes
- AND'ing of type
BUGS:
- test string isn't read when end of line is reached in absence of a message string
Tested:
- .doc
- .rtf
- .pdf
- .sh
- .gz
- .bz2
- .html
- .rpm
- .wav
Not supported by magic file:
- StarOffice
