Struts1.3.10深入源代码之核心类ActionForward类

  Action类的execute()方法返回一个ActionForward对象。ActionForward对象代表了Web资源的逻辑对象，这里的Web资源可以是JSP页面、JavaServlet或Action。
  下面是ActionForward类的源代码：

package org.apache.struts.action;

import org.apache.struts.config.ForwardConfig;

public class ActionForward extends ForwardConfig {
    /**
     * <p>Construct a new instance with default values.</p>
     */
    public ActionForward() {
        this(null, false);
    }

    /**
     * <p>Construct a new instance with the specified path.</p>
     *
     * @param path Path for this instance
     */
    public ActionForward(String path) {
        this(path, false);
    }

    /**
     * <p>Construct a new instance with the specified <code>path</code> and
     * <code>redirect</code> flag.</p>
     *
     * @param path     Path for this instance
     * @param redirect Redirect flag for this instance
     */
    public ActionForward(String path, boolean redirect) {
        super();
        setName(null);
        setPath(path);
        setRedirect(redirect);
    }

    /**
     * <p>Construct a new instance with the specified <code>name</code>,
     * <code>path</code> and <code>redirect</code> flag.</p>
     *
     * @param name     Name of this instance
     * @param path     Path for this instance
     * @param redirect Redirect flag for this instance
     */
    public ActionForward(String name, String path, boolean redirect) {
        super();
        setName(name);
        setPath(path);
        setRedirect(redirect);
    }

    /**
     * <p>Construct a new instance with the specified values.</p>
     *
     * @param name     Name of this forward
     * @param path     Path to which control should be forwarded or
     *                 redirected
     * @param redirect Should we do a redirect?
     * @param module   Module prefix, if any
     */
    public ActionForward(String name, String path, boolean redirect,
        String module) {
        super();
        setName(name);
        setPath(path);
        setRedirect(redirect);
        setModule(module);
    }

    /**
     * <p>Construct a new instance based on the values of another
     * ActionForward.</p>
     *
     * @param copyMe An ActionForward instance to copy
     * @since Struts 1.2.1
     */
    public ActionForward(ActionForward copyMe) {
        this(copyMe.getName(), copyMe.getPath(), copyMe.getRedirect(),
            copyMe.getModule());
    }
}
