    • add

      public final CompoundValidator<T> add(IValidator<T> validator)
      Adds an IValidator to the chain of validators.
      Parameters:
      validator - an IValidator to be added
      Returns:
      this ValidationError for chaining purposes

    • validate

      public final void validate(IValidatable<T> validatable)
      Description copied from interface: IValidator
      Validates the IValidatable instance. Validation errors should be reported using the IValidatable.error(IValidationError) method.
      Specified by:
      validate in interface IValidator<T>
      Parameters:
      validatable - the IValidatable instance being validated

    • getValidators

      public final List<IValidator<T>> getValidators()
      Gets an unmodifiable list of the registered validators.
      Returns:
      unmodifiable list of delegate IValidators inside this one

    • beforeRender

      public void beforeRender(Component component)
      Description copied from class: Behavior
      Called when a component is about to render.
      Overrides:
      beforeRender in class Behavior
      Parameters:
      component - the component that has this behavior coupled

    • afterRender

      public void afterRender(Component component)
      Description copied from class: Behavior
      Called when a component that has this behavior coupled was rendered.
      Overrides:
      afterRender in class Behavior
      Parameters:
      component - the component that has this behavior coupled

    • bind

      public void bind(Component component)
      Description copied from class: Behavior
      Bind this handler to the given component. This method is called by the host component immediately after this behavior is added to it. This method is useful if you need to do initialization based on the component it is attached and you can't wait to do it at render time. Keep in mind that if you decide to keep a reference to the host component, it is not thread safe anymore, and should thus only be used in situations where you do not reuse the behavior for multiple components.
      Overrides:
      bind in class Behavior
      Parameters:
      component - the component to bind to

    • unbind

      public void unbind(Component component)
      Description copied from class: Behavior
      Notifies the behavior it is removed from the specified component
      Overrides:
      unbind in class Behavior
      Parameters:
      component - the component this behavior is unbound from

    • detach

      public void detach(Component component)
      Description copied from class: Behavior
      Allows the behavior to detach any state it has attached during request processing.
      Overrides:
      detach in class Behavior
      Parameters:
      component - the component that initiates the detachment of this behavior

    • onException

      public void onException(Component component, RuntimeException exception)
      Description copied from class: Behavior
      In case an unexpected exception happened anywhere between Behavior.onComponentTag(org.apache.wicket.Component, org.apache.wicket.markup.ComponentTag) and Behavior.afterRender(org.apache.wicket.Component), onException() will be called for any behavior. Typically, if you clean up resources in Behavior.afterRender(Component), you should do the same in the implementation of this method.
      Overrides:
      onException in class Behavior
      Parameters:
      component - the component that has a reference to this behavior and during which processing the exception occurred
      exception - the unexpected exception

    • getStatelessHint

      public boolean getStatelessHint(Component component)
      Description copied from class: Behavior
      This method returns false if the behavior generates a callback url (for example ajax behaviors)
      Overrides:
      getStatelessHint in class Behavior
      Parameters:
      component - the component that has this behavior coupled.
      Returns:
      boolean true or false.

    • onComponentTag

      public void onComponentTag(Component component, ComponentTag tag)
      Description copied from class: Behavior
      Called any time a component that has this behavior registered is rendering the component tag.
      Overrides:
      onComponentTag in class Behavior
      Parameters:
      component - the component that renders this tag currently
      tag - the tag that is rendered

    • renderHead

      public void renderHead(Component component, IHeaderResponse response)
      Description copied from class: Behavior
      Render to the web response whatever the component wants to contribute to the head section.
      Specified by:
      renderHead in interface IComponentAwareHeaderContributor
      Overrides:
      renderHead in class Behavior
      Parameters:
      component - component which is contributing to the response. This parameter is here to give the component as the context for component-awares implementing this interface
      response - Response object

    • onConfigure

      public void onConfigure(Component component)
      Description copied from class: Behavior
      Called immediately after the onConfigure method in a component. Since this is before the rendering cycle has begun, the behavior can modify the configuration of the component (i.e. setVisible(false))
      Overrides:
      onConfigure in class Behavior
      Parameters:
      component - the component being configured

    • onEvent

      public void onEvent(Component component, IEvent<?> event)
      Description copied from class: Behavior
      Called to notify the behavior about any events sent to the component
      Specified by:
      onEvent in interface IComponentAwareEventSink
      Overrides:
      onEvent in class Behavior
      Parameters:
      component - component that owns this sink. For example, if the implementation of this interface is a Behavior then component parameter will contain the component to which the behavior is attached.

    • onRemove

      public void onRemove(Component component)
      Description copied from class: Behavior
      Called to notify that the component is being removed from its parent
      Overrides:
      onRemove in class Behavior
      Parameters:
      component - the removed component
