Class FQAN

java.lang.Object
  gov.bnl.gums.FQAN

public class FQAN
extends java.lang.Object

Represent a VOMS extended proxy credential as defined in http://edg-wp2.web.cern.ch/edg-wp2/security/voms/edg-voms-credential.pdf.

A Fully Qualified Attribute Name consists of a VO, a group, a role and a capability. Only the VO is mandatory. The syntax is /VO[/group[/subgroup(s)]][/Role=role][/Capability=cap].

The class will always check that every modification matches the regex /[\w-\.]+(/[\w-\.]+)*(/Role=[\w-\.]+)?(/Capability=[\w-\.]+)? which fully defines all the characters allowed. This differs slightly from the one contained in the specification, as it cointained some small errors. It matches the description of the syntax of the document.
