package org.apache.commons.jxpath;

 * A generic mechanism for accessing collections of name/value pairs.
 * Examples of such collections are HashMap, Properties,
 * ServletContext.  In order to add support for a new such collection
 * type to JXPath, perform the following two steps:
 * <ol>
 * <li>Build an implementation of the DynamicPropertyHandler interface
 * for the desired collection type.</li>
 * <li>Invoke the static method {@link JXPathIntrospector#registerDynamicClass
 * JXPathIntrospector.registerDynamicClass(class, handlerClass)}</li>
 * </ol>
 * JXPath allows access to dynamic properties using these three formats:
 * <ul>
 * <li>"myMap/myKey"
 * <li>"myMap[@name = 'myKey']"
 * <li>"myMap[name(.) = 'myKey']"
 * </ul>

public interface DynamicPropertyHandler {

     * Returns a list of dynamic property names for the supplied object.
     * @param object to inspect
     * @return String[]
    String[] getPropertyNames(Object object);

     * Returns the value of the specified dynamic property.
     * @param object to search
     * @param propertyName to retrieve
     * @return Object
    Object getProperty(Object object, String propertyName);

     * Modifies the value of the specified dynamic property.
     * @param object to modify
     * @param propertyName to modify
     * @param value to set
    void setProperty(Object object, String propertyName, Object value);
