Class AccessControlList

  • public class AccessControlList
extends Object
    An ACL object represents an Access Control List and wraps a White list and a Black list, Both lists make use of regular expressions for allowing/denying access to a certain resource. //#APIDOC_EXCLUDE_BEGIN Example, a ACL object is initialized as follows: ACL myacl = new ACL(); acl.setBlack( new File("black.txt") ); acl.setWhite( new File("white.txt") ); Properties client = new Property(); client.setProperty(); boolean ok = acl.isAllowed(); and the two files look as follows: white.txt # this is a commant # the section 'user' (allowed usernames) user: # all users are allowed .+? # the section 'msisdn' (allowed phone numbers) msisdn: # all business customers 39335.+? black.txt user: # specific users denied badboy goodgirl msisdn: # specific numbers denied 3933555.+? 39333444111 //#APIDOC_EXCLUDE_END Into each file, multiple sections are allowed. A specific client is allowed if:
    • it is not present into the black list, AND
    • it is present into the white list.
