isEffective

protected boolean isEffective()

Description copied from class: HtmlShadowElement

Returns whether the shadow element is effective

Overrides:

isEffective in class TemplateBasedShadowElement

compose

protected void compose(Component host)

Description copied from class: HtmlShadowElement

Composes the shadow element. It is called by HtmlShadowElement.afterCompose() if the shadow host is not null. Otherwise, it will skip this method call.

The second invocation is ignored. If you want to recreate child components, use HtmlShadowElement.recreate() instead.

Overrides:

compose in class TemplateBasedShadowElement

Parameters:

host - the shadow host component, never null.

isDynamicValue

public boolean isDynamicValue()

Description copied from interface: ShadowElementCtrl

Returns whether the shadow element contains a dynamic value, it means the shadow element cannot be destroyed after evaluated.

Specified by:

isDynamicValue in interface ShadowElementCtrl

Overrides:

isDynamicValue in class TemplateBasedShadowElement
