Allows to retrieve the names of the media to sort as well as other characteristics specified in the media.xml file.
The media's names and other characteristics are stored in the '../data/media.xml' file. The aim of this class is to allow other parts of this program to access quickly and simply to these informations.
The structure of the media.xml file must be :
< content >< media >< id >identifier< /id >< name >the name of the file as used by crowdFlower< /name > < characteristic >a first characteristic< /characteristic >< othercharac >another characteristic< /othercharac > < /media > ... < /content >
IMPORTANT: Identifiers must go from zero to $number_of_media without any gap. For instance, [0,2,1,5,4,3] works (the order does not matter), but [0,1,1337,42,5] does NOT.

| myDataBases.MediaBase.MediaBase | ( | String | path | ) |
Creates an instance of MediaBase and sets its attributes.
Generates a hashMap containing all the media and their characteristics, content, by parsing the path xml file. All the information contained in this file will be in the content attribute (as long as it is correctly xml formatted).
| path | Path to the file containing the data |
