Params::CallbackRequest provides functional and object-oriented callbacks
|
||
|
|
to method and function parameters. Callbacks may be either code references
|
||
|
|
provided to the new() constructor, or methods defined in subclasses of
|
||
|
|
Params::Callback. Callbacks are triggered either for every call to the
|
||
|
|
Params::CallbackRequest execute() method, or by specially named keys in
|
||
|
|
the parameters to execute().
|
||
|
|
|
||
|
|
The idea behind this module is to provide a sort of plugin architecture
|
||
|
|
for Perl templating systems. Callbacks are executed by the contents of a
|
||
|
|
request to the Perl templating server, before the templating system itself
|
||
|
|
executes. This approach allows you to carry out logical processing of data
|
||
|
|
submitted from a form, to affect the contents of the request parameters
|
||
|
|
before they're passed to the templating system for processing, and even to
|
||
|
|
redirect or abort the request before the templating system handles it.
