initialize,Node-method: Initialize a Node object.

Description

A Node has an associated type corresponding to the RDF component that it is representing. The list of possible types is "resource", "literal" or "blank".

Usage

"initialize"(.Object, world, literal, uri, blank, datatype_uri)

Arguments

.Object

the Node object to be initialized

world

a World object

literal

a literal character value to be assigned to the node

uri

a uri character value to be assigned to the node

blank

a blank node identifier to be assigned to the node

datatype_uri

a uri used to specify the datatype of a literal node, i.e. http://www.w3.org/2001/XMLSchema#string

Value

the Node object

Details

The url=' and 'literal=' arguments determine which type of Node is created. The Node type affects how the Node is processed in serialization, for example a Node created with 'node1 <- new("Node", literal="http://www.example.com")' is processed differently that a Node created with 'node1 <- new("Node", url="http://www.example.com")', with the former being processed as an RDF literal and the latter processed as an RDF resource.
