NAME GraphViz::ISA - Graphing class hierarchies at run-time VERSION version 1.100860 SYNOPSIS 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; DESCRIPTION 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: METHODS new 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. isatree 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. graph Takes a tree previously constructed by "isatree()" and traverses it, creating nodes and edges as it goes along.
