## javax.faces.component.behavior
Class ClientBehaviorBase

    java.lang.Object
      javax.faces.component.behavior.BehaviorBase
          javax.faces.component.behavior.ClientBehaviorBase

All Implemented Interfaces:
  Behavior, ClientBehavior, PartialStateHolder, StateHolder

Direct Known Subclasses:
  AjaxBehavior

    public class ClientBehaviorBase

extends BehaviorBase
implements ClientBehavior

ClientBehaviorBase is a convenience base class that implements the default concrete behavior of all methods defined by `ClientBehavior`.

Subclasses should either override getRendererType() to identify the `ClientBehaviorRenderer` to delegate to, or they should override `getScript()` to locally generate the desired Behavior script, and `decode()`.

Since:
  2.0

Constructor Summary
`ClientBehaviorBase()`

Method Summary
`void` | `decode(FacesContext context, UIComponent component)` Default implementation of of `ClientBehavior.decode(javax.faces.context.FacesContext, javax.faces.component.UIComponent)`.
`Set<ClientBehaviorHint>` | `getHints()` Default implementation of `ClientBehavior.getHints()`.
`protected ClientBehaviorRenderer` | `getRenderer(FacesContext context)` Convenience method to return the `ClientBehaviorRenderer` instance associated with this `ClientBehavior`, if any; otherwise, return `null`.
`String` | `getRendererType()` Returns the renderer type of the `ClientBehaviorRenderer` to use for the behavior.
`String` | `getScript(ClientBehaviorContext behaviorContext)` Default implementation of of `ClientBehavior.getScript(javax.faces.component.behavior.ClientBehaviorContext)`.

Constructor Detail

### ClientBehaviorBase

    public ClientBehaviorBase()

Method Detail

### getScript

    public String getScript(ClientBehaviorContext behaviorContext)

  Default implementation of of `ClientBehavior.getScript(javax.faces.component.behavior.ClientBehaviorContext)`. If a `ClientBehaviorRenderer` is available for the specified behavior renderer type, this method delegates to the `ClientBehaviorRenderer.getScript(javax.faces.component.behavior.ClientBehaviorContext, javax.faces.component.behavior.ClientBehavior)` method. Otherwise, this method returns null.

  Specified by:
    `getScript` in interface `ClientBehavior`
  Parameters:
    `behaviorContext` - the `ClientBehaviorContext`
  Returns:
    the script provided by the associated ClientBehaviorRenderer, or null if no ClientBehaviorRenderer is available.
  Throws:
    `NullPointerException` - if `behaviorContext` is `null`
  Since:
    2.0

### decode

    public void decode(FacesContext context,
                       UIComponent component)

  Default implementation of of `ClientBehavior.decode(javax.faces.context.FacesContext, javax.faces.component.UIComponent)`. If a `ClientBehaviorRenderer` is available for the specified behavior renderer type, this method delegates to the ClientBehaviorRenderer's decode() method. Otherwise, no decoding is performed.

  Specified by:
    `decode` in interface `ClientBehavior`
  Parameters:
    `context` - `FacesContext` for the request we are processing
    `component` - `UIComponent` the component associated with this `ClientBehavior`
  Throws:
    `NullPointerException` - if `context` or `component`is `null`.``
  Since:
    2.0

### getRendererType

    public String getRendererType()

  Returns the renderer type of the `ClientBehaviorRenderer` to use for the behavior. The default implementation returns null. Subclasses should either override this method to return a string that identifies the type of `ClientBehaviorRenderer` to use, or should override `getScript(javax.faces.component.behavior.ClientBehaviorContext)` and perform script rendering locally in the `ClientBehavior` implementation.

  Returns:
    the default renderer type, which is null.
  Since:
    2.0

### getHints

    public Set<ClientBehaviorHint> getHints()

  Default implementation of `ClientBehavior.getHints()`. By default, no hints are specified, and this method returns an empty, umodifiable set.

  Specified by:
    `getHints` in interface `ClientBehavior`
  Returns:
    an empty, unmodifiable set of `ClientBehaviorHint`s.
  Since:
    2.0

### getRenderer

    protected ClientBehaviorRenderer getRenderer(FacesContext context)

  Convenience method to return the `ClientBehaviorRenderer` instance associated with this `ClientBehavior`, if any; otherwise, return `null`.

  Parameters:
    `context` - `FacesContext` for the request we are processing
  Returns:
    `ClientBehaviorRenderer` instance from the current `RenderKit` or null.
  Throws:
    `NullPointerException` - if `context` is null.
  Since:
    2.0
