		<h1>[name]</h1>

		<p class="desc">A loader for loading a <em>.pdb</em> resource.<br>
		The <a href="http://en.wikipedia.org/wiki/Protein_Data_Bank_(file_format)">Protein Data Bank</a> file format is a textual file describing the three-dimensional structures of molecules.
		</p>

		<h2>Example</h2>

		<code>
		// instantiate a loader
		var loader = new THREE.PDBLoader();

		// load a PDB resource
		loader.load(
			// resource URL
			'models/molecules/caffeine.pdb',
			// called when the resource is loaded
			function ( pdb ) {

				var geometryAtoms = pdb.geometryAtoms;
				var geometryBonds = pdb.geometryBonds;
				var json = pdb.json;

				console.log( 'This molecule has ' + json.atoms.length + ' atoms' );

			},
			// called when loading is in progresses
			function ( xhr ) {

				console.log( ( xhr.loaded / xhr.total * 100 ) + '% loaded' );

			},
			// called when loading has errors
			function ( error ) {

				console.log( 'An error happened' );

			}
		);
		</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].
		</p>
		<p>
		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:null load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
		<p>
		[page:String url] — A string containing the path/URL of the <em>.pdb</em> file.<br />
		[page:Function onLoad] — (optional) A function to be called after loading is successfully completed. The function receives the object having the following properties. [page:BufferGeometry geometryAtoms], [page:BufferGeometry geometryBonds] and the [page:Object JSON] structure.<br />
		[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The argument will be the XMLHttpRequest instance, which contains [page:Integer total] and [page:Integer loaded] bytes.<br />
		[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.<br />
		</p>
		<p>
		Begin loading from url and call onLoad with the parsed response content.
		</p>

		<h3>[method:Object parse]( [param:String text] )</h3>
		<p>
		[page:String text] — The textual <em>pdb</em> structure to parse.
		</p>
		<p>
		Parse a <em>pdb</em> text and return a <em>JSON</em> structure.<br />
		</p>
