Link to this function canonical(literal) View Source

Produces the canonical form of a RDF.Literal.

Callback implementation for RDF.Datatype.canonical/1.

Link to this function canonical_lexical(value) View Source

Produces the lexical form of a value.

Callback implementation for RDF.Datatype.canonical_lexical/1.

Link to this function convert(value, opts) View Source

Converts a value into a proper native value.

If an invalid value is given an implementation should call super, which by default currently just returns nil.

Note: If a value is valid is determined by the lexical space of the implemented datatype, not by the Elixir semantics. For example, although 42 is a falsy value according to the Elixir semantics, this is not an element of the lexical value space of an xsd:boolean, so the RDF.Boolean implementation of this datatype calls super.

Callback implementation for RDF.Datatype.convert/2.

Link to this function id() View Source

The IRI of the datatype.

Callback implementation for RDF.Datatype.id/0.

Link to this function invalid_lexical(value) View Source

Produces the lexical form of an invalid value of a typed Literal.

The default implementation of the _using__ macro just returns to_string representation of the value.

Callback implementation for RDF.Datatype.invalid_lexical/1.

Link to this function lexical(literal) View Source

Produces the lexical form of a RDF.Literal.

Callback implementation for RDF.Datatype.lexical/1.

Link to this function new!(value, opts \\ %{}) View Source
Link to this function valid?(arg1) View Source

Determines if the value of a RDF.Literal is a member of lexical value space of its datatype.

Callback implementation for RDF.Datatype.valid?/1.
