NAME

"Devel::MAT::Tool::Reachability" - analyse how SVs are reachable

CONTENTS

DESCRIPTION

This Devel::MAT tool determines which SVs are reachable via any known roots and which are not. For reachable SVs, they are classified into several broad categories:
o SVs that directly make up the symbol table.
o SVs that form the padlist of functions or store the names of lexical variables.
o SVs that hold the value of lexical variables.
o User data stored in package globals, lexical variables, or referenced recursively via structures stored in them.
o Miscellaneous other SVs that are used to implement the internals of the interpreter.

SV METHODS

This tool adds the following SV methods.

    reachable



   $r = $sv->reachable



Returns true if the SV is reachable from a known root.
