		<h1>[name]</h1>

		<p class="desc">
			A loader for loading a JSON resource in the
			[link:https://github.com/mrdoob/three.js/wiki/JSON-Object-Scene-format-4 JSON Object/Scene format].<br /><br />
			This uses the [page:FileLoader] internally for loading files.
		</p>

		<h2>Code Example</h2>

		<code>
		const loader = new THREE.ObjectLoader();

		loader.load(
			// resource URL
			"models/json/example.json",

			// onLoad callback
			// Here the loaded data is assumed to be an object
			function ( obj ) {
				// Add the loaded object to the scene
				scene.add( obj );
			},

			// onProgress callback
			function ( xhr ) {
				console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
			},

			// onError callback
			function ( err ) {
				console.error( 'An error happened' );
			}
		);


		// Alternatively, to parse a previously loaded JSON structure
		const object = loader.parse( a_json_object );

		scene.add( object );
		</code>

		<h2>Constructor</h2>

		<h3>[name]( [param:LoadingManager manager] )</h3>
		<p>
			[page:LoadingManager manager] — The [page:LoadingManager loadingManager]
			for the loader to use. Default is [page:LoadingManager THREE.DefaultLoadingManager].<br /><br />
			Creates a new [name].
		</p>

		<h2>Properties</h2>
		<p>See the base [page:Loader] class for common properties.</p>

		<h2>Methods</h2>
		<p>See the base [page:Loader] class for common methods.</p>

		<h3>
			[method:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )
		</h3>
		<p>
			[page:String url] — the path or URL to the file. This can also be a
			[link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].<br />
			[page:Function onLoad] — Will be called when load completes. The argument
			will be the loaded [page:Object3D object].<br />
			[page:Function onProgress] (optional) — Will be called while load
			progresses. The argument will be the ProgressEvent instance, which
			contains .[page:Boolean lengthComputable], .[page:Integer total] and
			.[page:Integer loaded]. If the server does not set the Content-Length
			header; .[page:Integer total] will be 0.<br />
			[page:Function onError] (optional) — Will be called when load errors.<br />
		</p>
		<p>
			Begin loading from url and call onLoad with the parsed response content.
		</p>

		<h3>
			[method:Object3D parse]( [param:Object json], [param:Function onLoad] )
		</h3>
		<p>
			[page:Object json] — required. The JSON source to parse.<br /><br />
			[page:Function onLoad] — Will be called when parsed completes. The
			argument will be the parsed [page:Object3D object].<br /><br />
			Parse a `JSON` structure and return a three.js object. This is used
			internally by [page:.load]() but can also be used directly to parse a
			previously loaded JSON structure.
		</p>

		<h3>[method:Object parseGeometries]( [param:Object json] )</h3>
		<p>
			[page:Object json] — required. The JSON source to parse.<br /><br />

			This is used by [page:.parse]() to parse any [page:BufferGeometry geometries] in the JSON structure.
		</p>

		<h3>[method:Object parseMaterials]( [param:Object json] )</h3>
		<p>
			[page:Object json] — required. The JSON source to parse.<br /><br />

			This is used by [page:.parse]() to parse any materials in the JSON
			structure using [page:MaterialLoader].
		</p>

		<h3>[method:Object parseAnimations]( [param:Object json] )</h3>
		<p>
			[page:Object json] — required. The JSON source to parse.<br /><br />

			This is used by [page:.parse]() to parse any animations in the JSON
			structure, using [page:AnimationClip.parse]().
		</p>

		<h3>[method:Object parseImages]( [param:Object json] )</h3>
		<p>
			[page:Object json] — required. The JSON source to parse.<br /><br />

			This is used by [page:.parse]() to parse any images in the JSON structure,
			using [page:ImageLoader].
		</p>

		<h3>[method:Object parseTextures]( [param:Object json] )</h3>
		<p>
			[page:Object json] — required. The JSON source to parse.<br /><br />

			This is used by [page:.parse]() to parse any textures in the JSON
			structure.
		</p>

		<h3>
			[method:Object3D parseObject]( [param:Object json], [param:BufferGeometry geometries], [param:Material materials], [param:AnimationClip animations] )
		</h3>
		<p>
			[page:Object json] — required. The JSON source to parse.<br />
			[page:BufferGeometry geometries] — required. The geometries of the
			JSON.<br />
			[page:Material materials] — required. The materials of the JSON.<br />
			[page:AnimationClip animations] — required. The animations of the JSON.<br /><br />

			This is used by [page:.parse]() to parse any 3D objects in the JSON
			structure.
