Devel::MAT::Tool::Reachability3pm

Overview

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:

•

SVs that directly make up the symbol table.

•

SVs that form the padlist of functions or store the names of lexical variables.

•

SVs that hold the value of lexical variables.

•

User data stored in package globals, lexical variables, or referenced recursively via structures stored in them.

•

Miscellaneous other SVs that are used to implement the internals of the interpreter.

SV methods

This tool adds the following SV methods.
