    @Deprecated
public abstract class PolymerTemplate<M extends TemplateModel>
extends AbstractTemplate<M>

    Component for an HTML element declared as a polymer component. The HTML markup should be loaded using the JsModule annotation and the components should be associated with the web component element using the @Tag annotation.

    You may use Id annotation inside your template class for a field to reference an element inside your template via id attribute value. Note that the injected element will have functional limitations on the server side.

    • Method Detail

      • getChildren

        public Stream<Component> getChildren()

        Deprecated. 

        Gets the child components of this component.

        The default implementation finds child components by traversing each child Element tree.

        If the component is injected to a PolymerTemplate using the @Id annotation the getChildren method will only return children added from the server side and will not return any children declared in the template file.

        Please note that components defined using @Id are not child components since they are attached inside the Shadow DOM. Only components explicitly added through methods such as HasComponents.add(com.vaadin.flow.component.Component...) or Node.appendChild(Element...) are returned by this method.

        Overrides:

        getChildren in class Component

        Returns:

        the child components of this component
