NAME

Graph::Flowchart::Node - A node in a Graph::Flowchart, representing a block/expression

SYNOPSIS

use Devel::Graph;

my $graph = Devel::Graph->graph( '$a = 9 if $b == 1' );

print $graph->as_ascii();

DESCRIPTION

This module is used by Devel::Graph internally, there should be no need to use it directly.

EXPORT

Exports nothing on default but can export on request the following:

N_START N_END N_BLOCK N_IF N_THEN N_ELSE N_JOINT N_END N_FOR N_BODY
N_SUB
N_CONTINUE N_GOTO N_RETURN N_BREAK N_NEXT N_LAST
N_USE

METHODS

new()

my $node = Graph::Flowchart::Node->new( $text, $type, $label);
my $node = Graph::Flowchart::Node->new( $text, $type);

Create a new node of the given $type with the $text as label. The optional $label is the label for goto.

For instance:

LABEL: $a = 1;
goto LABEL;

would be turned into:

my $n1 = Graph::Flowchart::Node->new( "$a = 1;\n", N_BLOCK, 'LABEL'); 
my $n2 = Graph::Flowchart::Node->new( "goto LABEL;\n", N_GOTO);
