Constructor Detail

TsAclDBase

public TsAclDBase()

Construct an TsAclDBase. This will invoke the initDBase() method to initialize the database from the Config file.

Method Detail

initDBase

public void initDBase()

Initialize the TSAclDBase instance This will read special User and group information from the config file so that this class can respond correctly to ACVerifier methods. Here is what that part of the config file looks like: TopGroup = Users [Group-Users] jthomas/mypassword wykoff/gumbo toby/fubar Group K57 Group Admin [Group-Admin] Administrator/administrator [Group-K57] daford

getTopGroup

public java.security.acl.Group getTopGroup()

Return a reference to the Top Group in the Group hierarchy

getPrincipal

public java.security.Principal getPrincipal(java.lang.String name)

get Principal

putPrincipal

add Principal

exists

public boolean exists(java.security.Principal principal)

Return true if Principal exists

addPrincipalToGroup

public void addPrincipalToGroup(java.lang.String name,
                                java.lang.String group)
                         throws java.lang.IllegalArgumentException

Add a Principal to the specified Group

removePrincipalFromGroup

public void removePrincipalFromGroup(java.lang.String name,
                                     java.lang.String group)
                              throws java.lang.IllegalArgumentException

Remove Principal from Group
