Constructor Detail

AclTree

public AclTree(TsAclDBase aclDB,
               AuthChecker authck)

Constructor for the AclTree object. AclTree is simply a JPanel Subclass that the JTree resides in. Perhaps it would be better to make it a subclass of JTree.

Parameters:

aclDB - is the Object that keeps track of the existing Principals and the User/group hierarchy.

AuthChecker - object that maintains the User/Passowrd key Hashtable.

Method Detail

isModified

public boolean isModified()

Returns:

true if we modified the state of the TsAclDBase or the UserTable and it should be updated at the server.

setModified

public void setModified(boolean newStatus)

sets the modified status.

Parameters:

newStatus - Set the modified status to this

doAddExistingToGroup

protected boolean doAddExistingToGroup(com.ibm.tspaces.ac.adminapp.AclFolder selected)

Use wants to add one of the existing groups/users to the selected group (or user)

Parameters:

the - TreeNode that represents an Acl Principal

doAddNewGroup

protected boolean doAddNewGroup(com.ibm.tspaces.ac.adminapp.AclFolder selected)

User wants to add a new group to the selected group (or user)

Parameters:

the - TreeNode that represents an Acl Principal

Returns:

true if the operation is successfull

doAddNewUser

protected boolean doAddNewUser(com.ibm.tspaces.ac.adminapp.AclFolder selected)

Use wants to add a new User to the selected group (or user) This is similar to adding a group but you will be asked for a password and the userid and password will be added to a list of users and groups.

Parameters:

the - TreeNode that represents an Acl Principal where you want the user added.

Returns:

true if the operation is successfull

doRemoveGroup

protected boolean doRemoveGroup(com.ibm.tspaces.ac.adminapp.AclFolder selected,
                                com.ibm.tspaces.ac.adminapp.AclFolder parent)

User wants to remove the selected group or user from its parent. Note, this will not remove the group or user from the system. A future refinement would be to check if the selected group or user has no remaining parent (in belongsTo) and if so, ask the user if it should be deleted.

Parameters:

selected - Remove this group from its parent

parent - sever the ties

Returns:

return success or failure

doSetPassword

protected boolean doSetPassword(com.ibm.tspaces.ac.adminapp.AclFolder selected)

This sets the Password for an existing user.

Parameters:

selected - set the password for this principal

Returns:

success or failure

main

public static void main(java.lang.String[] argv)

This is just for development testing.
