=head1 DESCRIPTION |
26
|
|
|
|
|
|
|
|
27
|
|
|
|
|
|
|
This is a base class for batch actions. |
28
|
|
|
|
|
|
|
|
29
|
|
|
|
|
|
|
B Net::LDAP::Batch::Action objects will croak() if anything |
30
|
|
|
|
|
|
|
unusual happens. This approach assumes that Catastrophic Failure is a |
31
|
|
|
|
|
|
|
Good Thing. So use eval() if you need to catch exceptions. |
