Devel::MAT::Tool::Inrefs - annotate which SVs are referred to by others
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.
This tool adds the following SV methods.
@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
@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
