NAME ^

Devel::MAT::Tool::Inrefs - annotate which SVs are referred to by others

DESCRIPTION ^

This Devel::MAT tool annotates each SV with back-references from other SVs that refer to it. It follows the outrefs method of every heap SV and annotates the referred SVs with back-references pointing back to the SVs that refer to them.

SV METHODS ^

This tool adds the following SV methods.

inrefs

   @refs = $sv->inrefs

Returns a list of Reference objects for each of the SVs that refer to this one. This is formed by the inverse mapping along the SV graph from outrefs.

inrefs_strong

inrefs_weak

inrefs_direct

inrefs_indirect

inrefs_inferred

   @refs = $sv->inrefs_strong

   @refs = $sv->inrefs_weak

   @refs = $sv->inrefs_direct

   @refs = $sv->inrefs_indirect

   @refs = $sv->inrefs_inferred

Returns lists of Reference objects filtered by type, analogous to the various outrefs_* methods.
