public UrlResource(URL url) 
{
		Assert.notNull(url, "URL must not be null");
		this.url = url;
		this.cleanedUrl = getCleanedUrl(this.url, url.toString());
		this.uri = null;
}

Create a new UrlResource.

Parameters:

url - a URL

 public UrlResource(URI uri) throws MalformedURLException 
{
		Assert.notNull(uri, "URI must not be null");
		this.url = uri.toURL();
		this.cleanedUrl = getCleanedUrl(this.url, uri.toString());
		this.uri = uri;
}

Create a new UrlResource.

Parameters:

uri - a URI

Throws:

MalformedURLException - if the given URL path is not valid

 public UrlResource(String path) throws MalformedURLException 
{
		Assert.notNull(path, "Path must not be null");
		this.url = new URL(path);
		this.cleanedUrl = getCleanedUrl(this.url, path);
		this.uri = null;
}

Create a new UrlResource.

Parameters:

path - a URL path

Throws:

MalformedURLException - if the given URL path is not valid

 public Resource createRelative(String relativePath) throws MalformedURLException 
{
		if (relativePath.startsWith("/")) {
			relativePath = relativePath.substring(1);
		}
		return new UrlResource(new URL(this.url, relativePath));
}

This implementation creates a UrlResource, applying the given path relative to the path of the underlying URL of this resource descriptor.

 public boolean equals(Object obj) 
{
		return (obj == this ||
		    (obj instanceof UrlResource && this.cleanedUrl.equals(((UrlResource) obj).cleanedUrl)));
}

This implementation compares the underlying URL references.

 public String getDescription() 
{
		return "URL [" + this.url + "]";
}

This implementation returns a description that includes the URL.

 public File getFile() throws IOException 
{
		if (this.uri != null) {
			return ResourceUtils.getFile(this.uri, getDescription());
		}
		else {
			return ResourceUtils.getFile(this.url, getDescription());
		}
}

This implementation returns a File reference for the underlying URL/URI, provided that it refers to a file in the file system.

 protected File getFileForLastModifiedCheck() throws IOException 
{
		if (ResourceUtils.isJarURL(this.url)) {
			URL actualUrl = ResourceUtils.extractJarFileURL(this.url);
			return ResourceUtils.getFile(actualUrl);
		}
		else {
			return getFile();
		}
}

This implementation determines the underlying File (or jar file, in case of a resource in a jar/zip).

 public String getFilename() 
{
		return new File(this.url.getFile()).getName();
}

This implementation returns the name of the file that this URL refers to.

 public InputStream getInputStream() throws IOException 
{
		URLConnection con = this.url.openConnection();
		con.setUseCaches(false);
		return con.getInputStream();
}

This implementation opens an InputStream for the given URL. It sets the "UseCaches" flag to false, mainly to avoid jar file locking on Windows.

 public URI getURI() throws IOException 
{
		if (this.uri != null) {
			return this.uri;
		}
		else {
			return super.getURI();
		}
}

This implementation returns the underlying URI directly, if possible.

 public URL getURL() throws IOException 
{
		return this.url;
}

This implementation returns the underlying URL reference.

 public int hashCode() 
{
		return this.cleanedUrl.hashCode();
}

This implementation returns the hash code of the underlying URL reference.
