Class::Scaffold::App - Base class for framework applications
version 1.100980
use parent 'Class::Scaffold::App'; sub app_code { my $self = shift; $self->SUPER::app_code(@_); # ... application-specific tasks ... } main->new->run_app;
This is the base class for applications built with the Class::Scaffold framework, be they command-line applications or server-based applications. Applications will subclass this class, implement their specific tasks and call run_app().
run_app()
This is the main method that application subclasses should invoke. It calls the other methods described here. If there is an exception, it catches and logs it.
Called by run_app() right at the beginning. Override this method in your application-specific subclass to do any initialization your application needs.
Called by run_app() within a try/catch-block. Override this method to do the actual application-specific work.
try
catch
Called by run_app() right before the end. Override this method to do any cleanup your application needs.
Normally, app_init() is called only once, namely, when the program subclasses this class and does main->new->run_app. However, if used from within mod_perl, for example, the application is a cached object and run_app() is called repeatedly from the outside. In this case, app_init() should be called only once. We do this with the boolean flag initialized().
app_init()
main->new->run_app
initialized()
If called without an argument, returns the boolean value (0 or 1). If called with an argument, it normalizes it to the boolean value. That is, the values 0, undef and the empty string become 0; everything else becomes 1.
Examples:
$obj->initialized($value); my $value = $obj->initialized;
There are also the following helper methods for this accessor:
set_initialized
initialized_set
Sets the boolean value to 1.
Example:
$obj->set_initialized;
clear_initialized
initialized_clear
Clears the boolean value by setting it to 0.
$obj->clear_initialized;
