GraphViz::ISA - Graphing class hierarchies at run-time

version 1.100860

  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 methods described here 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.
