GraphViz::ISA - Graphing @ISA hierarchies at run-time
use GraphViz::ISA;
my $p = Some::Class->new;
my $g1 = GraphViz::ISA->new($p);
print $g1->as_png;
my $g2 = GraphViz::ISA->new('Some::Other::Module');
print $g2->as_png;
This class constructs a graph showing the @ISA hierarchy (note: not object hierarchies) from a package name or a blessed scalar.
The following methods are defined by this class; all other method calls are passed to the underlying GraphViz object:
This constructs the object itself and takes a parameter. The parameter can be either a package name or a scalar blessed into a package. It then calls isatree() and hands the result to graph(). Then it returns the newly constructed object.
Takes a package name as a parameter and traverses the indicated package's @ISA recursively, constructing a hash of hashes. If a package's @ISA is empty, it has an empty hashref as the value in the tree.
Takes a tree previously constructed by isatree() and traverses it, creating nodes and edges as it goes along.
None known so far. If you find any bugs or oddities, please do inform the author.
