		<h1>[name]</h1>

		<p class="desc">
			A low level class for loading resources with XMLHttpRequest, used internaly by most loaders.
			It can also be used directly to load any file type that does not have a loader.
		</p>

		<h2>Code Example</h2>
		<code>
		var loader = new THREE.FileLoader();

		//load a text file and output the result to the console
		loader.load(
			// resource URL
			'example.txt',

			// onLoad callback
			function ( data ) {
				// output the text to the console
				console.log( data )
			},

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

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

		<p>
			<em>Note:</em> The cache must be enabled using
			<code>THREE.Cache.enabled = true;</code>
			This is a global property and only needs to be set once to be used by all loaders that use FileLoader internally.
			[page:Cache Cache] is a cache module that holds the response from each request made through this loader, so each file is requested once.
		</p>


		<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:DefaultLoadingManager].
		</p>

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

		<h3>[property:String mimeType]</h3>
		<p>
			The expected [link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types mimeType].
			See [page:.setMimeType]. Default is *undefined*.
		</p>

		<h3>[property:String responseType]</h3>
		<p>The expected response type. See [page:.setResponseType]. Default is *undefined*.</p>

		<h3>[property:String withCredentials]</h3>
		<p>
			Whether the XMLHttpRequest uses credentials. See [page:.setWithCredentials].
			Default is *undefined*.
		</p>

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

		<h3>[method:XMLHttpRequest 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] (optional) — Will be called when loading completes. The argument will be the loaded response.<br />
			[page:Function onProgress] (optional) — Will be called while load progresses. The argument will be the XMLHttpRequest instance,
				which contains .[page:Integer total] and .[page:Integer loaded] bytes.<br />
			[page:Function onError] (optional) — Will be called if an error occurs.<br /><br />

			Load the URL and pass the response to the onLoad function.
		</p>

		<h3>[method:FileLoader setMimeType]( [param:String mimeType] )</h3>
		<p>
			Set the expected [link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types mimeType]
			of the file being loaded. Note that in many cases this will be determined automatically, so by default it is *undefined*.
		</p>

		<h3>[method:FileLoader setResponseType]( [param:String responseType] )</h3>
		<p>
			Change the response type. Valid values are:<br />
			[page:String text] or empty string (default) - returns the data as [page:String String].<br />
			[page:String arraybuffer] - loads the data into a [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer ArrayBuffer] and returns that.<br />
			[page:String blob] - returns the data as a [link:https://developer.mozilla.org/en/docs/Web/API/Blob Blob].<br />
			[page:String document] - parses the file using the [link:https://developer.mozilla.org/en-US/docs/Web/API/DOMParser DOMParser].<br />
			[page:String json] - parses the file using [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse JSON.parse].<br />
		</p>

		<h3>[method:FileLoader setWithCredentials]( [param:Boolean value] )</h3>
		<p>
			Whether the XMLHttpRequest uses credentials such as cookies, authorization headers or
			TLS client certificates. See [link:https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials XMLHttpRequest.withCredentials].<br />
			Note that this has no effect if you are loading files locally or from the same domain.
