Detailed Description

Filesystem Specific Attributes (FSA) class

this class handle the storage of attributes into and from the archive the have not filesystem specific knownledge. This aspect is managed by filesystem_specific_attribute_list that upon system call will create the liste of FSA and given the list of FSA will try to set them back to the filesystem

Constructor & Destructor Documentation

constructor used to before reading the FSA from filesystem

Note:
when the underlying filesystem does not support the requested EA the constructor of the inherited class should throw an exception of type Erange. Only valid object should be built, that is object containing the value of the FSA found on the filesystem.
