Creates a new jQuery.rdf object. This should be invoked as a method rather than constructed using new; indeed you will usually want to generate these objects using a method such as {@link jQuery#rdf} or {@link jQuery.rdf#where}.

- * @class

A jQuery.rdf object represents the results of a query over its {@link jQuery.rdf#databank}. The results of a query are a sequence of objects which represent the bindings of values to the variables used in filter expressions specified using {@link jQuery.rdf#where} or {@link jQuery.rdf#optional}. Each of the objects in this sequence has associated with it a set of triples that are the sources for the variable bindings, which you can get at using {@link jQuery.rdf#sources}.

- *

The {@link jQuery.rdf} object itself is a lot like a {@link jQuery} object. It has a {@link jQuery.rdf#length} and the individual matches can be accessed using [n], but you can also iterate through the matches using {@link jQuery.rdf#map} or {@link jQuery.rdf#each}.

- *

{@link jQuery.rdf} is designed to mirror the functionality of SPARQL while providing an interface that's familiar and easy to use for jQuery programmers.

- * @param {Object} [options] - * @param {jQuery.rdf.databank} [options.databank] The databank that this query should operate over. - * @param {jQuery.rdf.triple[]} [options.triples] A set of triples over which the query operates; this is only used if options.databank isn't specified, in which case a new databank with these triples is generated. - * @param {Object} [options.namespaces] An object representing a set of namespace bindings.

Creates a new jQuery.rdf object. This should be invoked as a method rather than constructed using new; indeed you will usually want to generate these objects using a method such as {@link jQuery#rdf} or {@link jQuery.rdf#where}.

- * @class

A jQuery.rdf object represents the results of a query over its {@link jQuery.rdf#databank}. The results of a query are a sequence of objects which represent the bindings of values to the variables used in filter expressions specified using {@link jQuery.rdf#where} or {@link jQuery.rdf#optional}. Each of the objects in this sequence has associated with it a set of triples that are the sources for the variable bindings, which you can get at using {@link jQuery.rdf#sources}.

- *

The {@link jQuery.rdf} object itself is a lot like a {@link jQuery} object. It has a {@link jQuery.rdf#length} and the individual matches can be accessed using [n], but you can also iterate through the matches using {@link jQuery.rdf#map} or {@link jQuery.rdf#each}.

- *

{@link jQuery.rdf} is designed to mirror the functionality of SPARQL while providing an interface that's familiar and easy to use for jQuery programmers.

- * @param {Object} [options] - * @param {jQuery.rdf.databank} [options.databank] The databank that this query should operate over. - * @param {jQuery.rdf.triple[]} [options.triples] A set of triples over which the query operates; this is only used if options.databank isn't specified, in which case a new databank with these triples is generated. - * @param {Object} [options.namespaces] An object representing a set of namespace bindings.

Otherwise, if it's a Javascript boolean or numeric value, it is interpreted as a value with a xsd:boolean or xsd:double datatype. In all other cases it's interpreted as a literal as defined in Turtle syntax. - * @param {Object} [options] Initialisation options for the literal. - * @param {String} [options.datatype] The datatype for the literal. This should be a safe CURIE; in other words, it can be in the format uri or [curie].

Must not be specified if options.datatype is also specified. - * @param {Object} [options.namespaces] An object representing a set of namespace bindings used when interpreting a CURIE in the datatype. - * @param {String|jQuery.uri} [options.base] The base URI used to interpret a relative URI in the datatype. - * @returns {jQuery.rdf.literal} The newly-created literal. - * @throws {String} Errors if the string is not in a recognised format or if both options.datatype and options.lang are specified. - * @example trueLiteral = $.rdf.literal(true); - * @example numericLiteral = $.rdf.literal(5); - * @example dateLiteral = $.rdf.literal('"2009-07-13"^^xsd:date', { namespaces: ns }); - * @see jQuery.rdf.pattern - * @see jQuery.rdf.triple - * @see jQuery.rdf.resource - * @see jQuery.rdf.blank - */ - $.rdf.literal = function (value, options) { - var literal; - if (memLiteral[value]) { - return memLiteral[value]; - } - literal = new $.rdf.literal.fn.init(value, options); - if (memLiteral[literal]) { - return memLiteral[literal]; - } else { - memLiteral[literal] = literal; - return literal; - } - }; - - $.rdf.literal.fn = $.rdf.literal.prototype = { - /** - * Always fixed to 'literal' for literals. - * @type String - */ - type: 'literal', - /** - * The value of the literal as a string. - * @type String - */ - value: undefined, - /** - * The language of the literal, if it has one; otherwise undefined. - * @type String - */ - lang: undefined, - /** - * The datatype of the literal, if it has one; otherwise undefined. - * @type jQuery.uri - */ - datatype: undefined, - - init: function (value, options) { - var - m, datatype, - opts = $.extend({}, $.rdf.literal.defaults, options); - if (opts.lang !== undefined && opts.datatype !== undefined) { - throw "Malformed Literal: Cannot define both a language and a datatype for a literal (" + value + ")"; - } - if (opts.datatype !== undefined) { - datatype = $.safeCurie(opts.datatype, { namespaces: opts.namespaces }); - $.extend(this, $.typedValue(value.toString(), datatype)); - } else if (opts.lang !== undefined) { - this.value = value.toString(); - this.lang = opts.lang; - } else if (typeof value === 'boolean') { - $.extend(this, $.typedValue(value.toString(), xsdNs + 'boolean')); - } else if (typeof value === 'number') { - $.extend(this, $.typedValue(value.toString(), xsdNs + 'double')); - } else if (value === 'true' || value === 'false') { - $.extend(this, $.typedValue(value, xsdNs + 'boolean')); - } else if ($.typedValue.valid(value, xsdNs + 'integer')) { - $.extend(this, $.typedValue(value, xsdNs + 'integer')); - } else if ($.typedValue.valid(value, xsdNs + 'decimal')) { - $.extend(this, $.typedValue(value, xsdNs + 'decimal')); - } else if ($.typedValue.valid(value, xsdNs + 'double') && - !/^\s*([\-\+]?INF|NaN)\s*$/.test(value)) { // INF, -INF and NaN aren't valid literals in Turtle - $.extend(this, $.typedValue(value, xsdNs + 'double')); - } else { - m = literalRegex.exec(value); - if (m !== null) { - this.value = (m[2] || m[4]).replace(/\\"/g, '"'); - if (m[9]) { - datatype = $.rdf.resource(m[9], opts); - $.extend(this, $.typedValue(this.value, datatype.value)); - } else if (m[7]) { - this.lang = m[7]; - } - } else { - throw "Malformed Literal: Couldn't recognise the value " + value; - } - } - return this; - }, // end init - - /** - * Returns a RDF/JSON representation of this blank node. - * @returns {Object} - */ - dump: function () { - var e = { - type: 'literal', - value: this.value.toString() - }; - if (this.lang !== undefined) { - e.lang = this.lang; - } else if (this.datatype !== undefined) { - e.datatype = this.datatype.toString(); - } - return e; - }, - - /** - * Returns a string representing this resource in Turtle format. - * @returns {String} - */ - toString: function () { - var val = '"' + this.value + '"'; - if (this.lang !== undefined) { - val += '@' + this.lang; - } else if (this.datatype !== undefined) { - val += '^^<' + this.datatype + '>'; - } - return val; - } - }; - - $.rdf.literal.fn.init.prototype = $.rdf.literal.fn; - - $.rdf.literal.defaults = { - base: $.uri.base(), - namespaces: {}, - datatype: undefined, - lang: undefined - }; - -})(jQuery); diff --git a/htroot/jslicense.html b/htroot/jslicense.html index a3957e628..59b8bb6fe 100755 --- a/htroot/jslicense.html +++ b/htroot/jslicense.html @@ -88,11 +88,6 @@ WTFPL jquery.query-2.1.7.js - - jquery.rdfquery.core-1.0.js - Expat - jquery.rdfquery.core-1.0.js - jquery.tagsinput.min.js Expat
