=head1 DESCRIPTION |
25
|
|
|
|
|
|
|
|
26
|
|
|
|
|
|
|
An object of this class is a passphrase recogniser that accepts any |
27
|
|
|
|
|
|
|
passphrase whatsoever. This is a subclass of L, and |
28
|
|
|
|
|
|
|
this document assumes that the reader is familiar with the documentation |
29
|
|
|
|
|
|
|
for that class. |
30
|
|
|
|
|
|
|
|
31
|
|
|
|
|
|
|
This type of passphrase recogniser is obviously of no use at all in |
32
|
|
|
|
|
|
|
controlling access to any resource. Its use is to permit a resource to |
33
|
|
|
|
|
|
|
be public in a system that expects some type of passphrase access control. |

These methods are part of the standard L interface. |
103

The L method always returns true, and the L method |
104

returns the empty string (the shortest of the infinite number of correct |
105
|
