19 The Attean::TermMap class represents a one-way mapping process from and
20 to Attean::API::Term objects. This mapping may rename the blank
21 identifiers, skolemize nodes, or map the nodes in some other, custom
22 way.
23
24 It conforms to the Attean::API::Mapper role.
25
27 "mapper"
28 A CODE reference that will map Attean::API::Term objects to
29 (possibly different) term objects.
30
32 "canonicalization_map"
33 Returns a new Attean::TermMap that canonicalizes recognized typed
34 Attean::API::Literal values.
35
36 "uuid_blank_map"
37 Returns a new Attean::TermMap that renames blank nodes with UUID
38 values.
39
40 "short_blank_map"
41 Returns a new Attean::TermMap that renames blank nodes with short
42 alphabetic names (e.g. _:a, _:b).
43
44 "rewrite_map( \%map )"
45 Given %map whose keys are term "as_string" serializations, and
46 objects are Attean::API::Term objects, returns a new term map
47 object that maps terms matching entries in %map, and all other
48 terms to themselves.
49
51 "map( $term )"
52 Returns the term that is mapped to by the supplied $term.
53
54 "binding_mapper"
55 Returns a mapping function reference that maps Attean::API::Binding
56 objects by mapping their constituent mapped Attean::API::Term
57 objects.
