=head1 DESCRIPTION |
90
|
|
|
|
|
|
|
|
91
|
|
|
|
|
|
|
This is an abstract class that extends the Net::ACL::File class. It has the |
92
|
|
|
|
|
|
|
common features of loading a standard access-list in Cisco-notation. |
93
|
|
|
|
|
|
|
It replaces the load constructor and adds a loadmatch() method that should be |
94
|
|
|
|
|
|
|
replaced in any sub-class. |
95
|
|
|
|
|
|
|
|
96
|
|
|
|
|
|
|
Any sub-classes should register them self with the Net::ACL::File class using |
97
|
|
|
|
|
|
|
the add_listtype() class method. After this, classes are constructed by the |
98
|
|
|
|
|
|
|
Net::ACL::File new() constructor. |

=head1 CONSTRUCTOR |
101
|
|
|
|
|
|
|
|
102
|
|
|
|
|
|
|
There should be no reason to use nor change the constructor of this class. |
103
|
|
|
|
|
|
|
However - It gets a Cisco::Reconfig object as argument. It returns a reference |
104
|
|
|
|
|
|
|
to the object created from the data in the Cisco::Reconfig object. |

|
|
|
|
The loadmatch() method is called with an access-list clause - normally a single |
113
|
|
|
|
|
|
|
line. It should construct a Net::ACL::Rule object and add it using the |
114
|
|
|
|
|
|
|
add_rule() inherited method. |
