Example 1 with IJavaScriptCompressor

use of org.apache.wicket.javascript.IJavaScriptCompressor in project wicket by apache.

the class CompositeJavaScriptCompressor method process.

/**
 * Compresses the given original content in the order of compressors. If no compressor has been
 * given the original content is going to be returned.
 */

Example 2 with IJavaScriptCompressor

use of org.apache.wicket.javascript.IJavaScriptCompressor in project wicket by apache.

the class ResourceSettings method setJavaScriptCompressor.

/**
 * Set the javascript compressor implemententation use e.g. by
 * {@link org.apache.wicket.request.resource.JavaScriptPackageResource
 * JavaScriptPackageResource}. A typical implementation will remove comments and whitespace. But
 * a no-op implementation is available as well.
 *
 * @param compressor
 *            The implementation to be used
 * @return The old value
 * @return {@code this} object for chaining

Example 3 with IJavaScriptCompressor

use of org.apache.wicket.javascript.IJavaScriptCompressor in project wicket by apache.

the class ResourceBundles method addJavaScriptBundle.

/**
 * Adds a javascript bundle that is automatically generated by concatenating the given package
 * resources. If the given resources depend on each other, you should make sure that the
 * resources are provided in the order they need to be concatenated. If the resources depend on
 * other resources, that are not part of the bundle, the bundle will inherit these dependencies.
 *
 * This method is equivalent to {@link #addBundle(HeaderItem)} with a
 * {@link JavaScriptHeaderItem} for a {@link ConcatResourceBundleReference}.
 *
 * @param scope
 *            The {@linkplain ResourceReference#getScope() scope} of the bundle
 * @param defer
 *            specifies that the execution of a script should be deferred (delayed) until after
 *            the page has been loaded.
 * @param name
 *            The name of the resource. This will show up as the filename in the markup.
 * @param references
 *            The resources this bundle will consist of.
 * @return the newly created bundle
