Examples with FeatureDescriptor java.beans.FeatureDescriptor used on opensource projects

Example 6 with FeatureDescriptor

use of java.beans.FeatureDescriptor in project Activiti by Activiti.

the class ResourceBundleELResolver method getFeatureDescriptors.

/**
	 * If the base object is a ResourceBundle, returns an Iterator containing the set of keys
	 * available in the ResourceBundle. Otherwise, returns null. The Iterator returned must contain
	 * zero or more instances of java.beans.FeatureDescriptor. Each info object contains information
	 * about a key in the ResourceBundle, and is initialized as follows:
	 * <ul>
	 * <li>displayName - The String key name</li>
	 * <li>name - Same as displayName property</li>
	 * <li>shortDescription - Empty string</li>
	 * <li>expert - false</li>
	 * <li>hidden - false</li>
	 * <li>preferred - true</li>
	 * </ul>
	 * In addition, the following named attributes must be set in the returned FeatureDescriptors:
	 * <ul>
	 * <li>{@link ELResolver#TYPE} - String.class.</li>
	 * <li>{@link ELResolver#RESOLVABLE_AT_DESIGN_TIME} - true</li>
	 * </ul>
	 * 
	 * @param context
	 *            The context of this evaluation.
	 * @param base
	 *            The bundle to analyze. Only bases of type ResourceBundle are handled by this
	 *            resolver.
	 * @return An Iterator containing zero or more (possibly infinitely more) FeatureDescriptor
	 *         objects, each representing a key in this bundle, or null if the base object is not a
	 *         ResourceBundle.
