## Class ExtensibleJavaScriptStack

- java.lang.Object
- - org.apache.tapestry5.services.javascript.ExtensibleJavaScriptStack

- All Implemented Interfaces:
    JavaScriptStack

      @UsesOrderedConfiguration(value=StackExtension.class)
      public class ExtensibleJavaScriptStack
      extends Object
      implements JavaScriptStack

  An extensible implementation of `JavaScriptStack` that can be used as the implementation of a service. The contributions to the service are used to supply the libraries, stylesheets, and initialization for a JavaScriptStack, allowing the stack to be more dynamically configured. In practice, one will use `ServiceBinder.bind(Class, Class)` and `ServiceBindingOptions.withMarker(Class...)` to construct the service, then use the marker annotation to inject the service when contributing the service into to the `JavaScriptStackSource`.

  A limitation of this implementation is that the contributed assets are not localized at all.

- - ### Constructor Detail

    - #### ExtensibleJavaScriptStack

          public ExtensibleJavaScriptStack(AssetSource assetSource,
                                   List<StackExtension> configuration)

  - ### Method Detail

    - #### getStacks

          public List<String> getStacks()

      Description copied from interface: `JavaScriptStack`
      Returns a list of JavaScriptStack names that this stack depends on. Each stack will be processed before the current stack (thus a dependency stack's libraries, stylesheets and initialization is emitted before the dependent stack).
      Specified by:
        `getStacks` in interface `JavaScriptStack`

    - #### getJavaScriptLibraries

          public List<Asset> getJavaScriptLibraries()

      Description copied from interface: `JavaScriptStack`
      Returns a list of localized assets for JavaScript libraries that form the stack.
      Specified by:
        `getJavaScriptLibraries` in interface `JavaScriptStack`

    - #### getStylesheets

          public List<StylesheetLink> getStylesheets()

      Description copied from interface: `JavaScriptStack`
      Returns a list of localized links for stylesheets that form the stack.
      Specified by:
        `getStylesheets` in interface `JavaScriptStack`

    - #### getInitialization

          public String getInitialization()

      Description copied from interface: `JavaScriptStack`
      Returns static JavaScript initialization for the stack. This block of JavaScript code will be added to the page that imports the stack. The code executes outside of any other function (i.e., the code is not deferred until the DOM is loaded). As with the other methods, if localization is a factor, the result of this method should be localized.
      Specified by:
        `getInitialization` in interface `JavaScriptStack`

    - #### getModules

          public List<String> getModules()

      Description copied from interface: `JavaScriptStack`
      Returns a list of modules to include with the stack, when aggregating the stack's JavaScript. It is still necessary to explicitly require such modules.
      Specified by:
        `getModules` in interface `JavaScriptStack`
      See Also:
        `ModuleManager`, `SymbolConstants.COMBINE_SCRIPTS`

    - #### getJavaScriptAggregationStrategy

          public JavaScriptAggregationStrategy getJavaScriptAggregationStrategy()

      Description copied from interface: `JavaScriptStack`
      Identifies how to aggregate JavaScript within the stack. The default is `JavaScriptAggregationStrategy.COMBINE_AND_MINIMIZE`.
      Specified by:
        `getJavaScriptAggregationStrategy` in interface `JavaScriptStack`
