package PPI::Statement::Scheduled;
=pod
=head1 NAME
PPI::Statement::Scheduled - A scheduled code block
=head1 INHERITANCE
PPI::Statement::Scheduled
isa PPI::Statement::Sub
isa PPI::Statement
isa PPI::Node
isa PPI::Element
=head1 DESCRIPTION
A scheduled code block is one that is intended to be run at a specific
time during the loading process.
There are five types of scheduled block:
BEGIN {
# Executes as soon as this block is fully defined
...
}
CHECK {
# Executes after overall compile-phase in reverse order
...
}
UNITCHECK {
# Executes after compile-phase of individual module in reverse order
...
}
INIT {
# Executes just before run-time
...
}
END {
# Executes as late as possible in reverse order
...
}
Technically these scheduled blocks are actually subroutines, and in fact
may have 'sub' in front of them.
=head1 METHODS
=cut
use strict;
use PPI::Statement::Sub ();
use vars qw{$VERSION @ISA};
BEGIN {
$VERSION = '1.215';
@ISA = 'PPI::Statement::Sub';
}
sub __LEXER__normal { '' }
sub _complete {
my $child = $_[0]->schild(-1);
return !! (
defined $child
and
$child->isa('PPI::Structure::Block')
and
$child->complete
);
}
=pod
=head2 type
The C<type> method returns the type of scheduled block, which should always be
one of C<'BEGIN'>, C<'CHECK'>, C<'UNITCHECK'>, C<'INIT'> or C<'END'>.
=cut
sub type {
my $self = shift;
my @children = $self->schildren or return undef;
$children[0]->content eq 'sub'
? $children[1]->content
: $children[0]->content;
}
# This is actually the same as Sub->name
sub name {
shift->type(@_);
}

=pod
=head1 TO DO
