Field Detail

### inherit

    protected String inherit

  The name of the ForwardConfig that this object should inherit properties from.

### extensionProcessed

    protected boolean extensionProcessed

  Have the inheritance values for this class been applied?

### name

    protected String name

  The unique identifier of this forward, which is used to reference it in `Action` classes.

### path

    protected String path

  The URL to which this `ForwardConfig` entry points, which must start with a slash ("/") character. It is interpreted according to the following rules:

  - If `contextRelative` property is `true`, the path is considered to be context-relative within the current web application (even if we are in a named module). It will be prefixed by the context path to create a server-relative URL.
  - If the `contextRelative` property is false, the path is considered to be the module-relative portion of the URL. It will be used as the replacement for the `$P` marker in the `forwardPattern` property defined on the `ControllerConfig` element for our current module. For the default `forwardPattern` value of `$C$M$P`, the resulting server-relative URL will be the concatenation of the context path, the module prefix, and the `path` from this `ForwardConfig`.

### module

    protected String module

  The prefix of the module to which this `ForwardConfig` entry points, which must start with a slash ("/") character.

  Usage note: If a forward config is used in a hyperlink, and a module is specified, the path must lead to another action and not directly to a page. This is in keeping with rule that in a modular application all links must be to an action rather than a page.

### redirect

    protected boolean redirect

  Should a redirect be used to transfer control to the specified path?

### command

    protected String command

  The name of a `commons-chain` command which should be looked up and executed before Struts dispatches control to the view represented by this config.

### catalog

    protected String catalog

  The name of a `commons-chain` catalog in which `command` should be looked up. If this value is undefined, then the command will be looked up in the "default" catalog. This value has no meaning except in the context of the `command` property.

                                               ActionConfig actionConfig)

  Traces the hierarchy of this object to check if any of the ancestors are extending this instance.

  Parameters:
    `moduleConfig` - The `ModuleConfig` that this config is from.
    `actionConfig` - The `ActionConfig` that this config is from, if applicable. This parameter must be null if this forward config is a global forward.
  Returns:
    true if circular inheritance was detected.

### inheritFrom

    public void inheritFrom(ForwardConfig config)
                     throws ClassNotFoundException,
                            IllegalAccessException,
                            InstantiationException,
                            InvocationTargetException

  Inherit values that have not been overridden from the provided config object. Subclasses overriding this method should verify that the given parameter is of a class that contains a property it is trying to inherit:

       if (config instanceof MyCustomConfig) {
           MyCustomConfig myConfig =
               (MyCustomConfig) config;

           if (getMyCustomProp() == null) {
               setMyCustomProp(myConfig.getMyCustomProp());
           }
       }

  If the given `config` is extending another object, those extensions should be resolved before it's used as a parameter to this method.

  Parameters:
    `config` - The object that this instance will be inheriting its values from.
  Throws:
    `ClassNotFoundException`
    `IllegalAccessException`
    `InstantiationException`
    `InvocationTargetException`
  See Also:
    `processExtends(ModuleConfig, ActionConfig)`

### processExtends

    public void processExtends(ModuleConfig moduleConfig,
                               ActionConfig actionConfig)
                        throws ClassNotFoundException,
                               IllegalAccessException,
                               InstantiationException,
                               InvocationTargetException

  Inherit configuration information from the ForwardConfig that this instance is extending. This method verifies that any forward config object that it inherits from has also had its processExtends() method called.

  Parameters:
    `moduleConfig` - The `ModuleConfig` that this config is from.
    `actionConfig` - The `ActionConfig` that this config is from, if applicable. This must be null for global forwards.
  Throws:

    `IllegalAccessException`
    `InstantiationException`
    `InvocationTargetException`
