Attean::API::Binding - Name to term bindings
This document describes Attean::API::Binding version 0.003_01
The Attean::API::Binding role defines a common API for all objects that map names to Attean::API::Term objects. This includes triples, quads, and SPARQL results (variable bindings).
Classes consuming this role must provide the following methods:
value( $name )
Returns the Attean::API::Term object mapped to the variable named
undefif no such term is mapped.
Returns a list of the variable names mapped to Attean::API::Term objects in this mapping.
apply_map( $mapper )
Returns a new mapping object (of the same class as the referent) with term objects rewritten using the supplied Attean::Mapper object
This role provides default implementations of the following methods:
Returns a HASH mapping variable names to Attean::API::Term objects.
Returns a list of Attean::API::Term objects corresponding to the variable names returned by the referent's
Returns a string serialization of the Attean::API::Term objects in the order they are returned by the referent's
Returns a string serialization of the variable bindings.
Returns true if any variable is bound to an Attean::API::Blank term, false otherwise.
