=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 ();

our $VERSION = '1.276';

our @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 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(@_);
}
