Method Details

createAndBind

elemental.dom.Node createAndBind(StateNode node)

Creates and binds a DOM node for the given state node. For state nodes based on templates, the root element of the template is returned.

Parameters:

node - the state node for which to create a DOM node, not null

Returns:

the DOM node, not null

bind

void bind(StateNode stateNode,
 elemental.dom.Node node)

Binds a DOM node for the given state node.

Parameters:

stateNode - the state node to bind, not null

node - the DOM node, not null

getStrategies

<T extends BindingStrategy<?>> JsArray<T> getStrategies(Predicate<BindingStrategy<?>> predicate)

Gets the strategies with a specific type T using filtering predicate.

Predicate normally should be based on Class<T>#isInstance() but this method is not available in GWT so predicate instanceof T should be used. It's the developer responsibility to make sure that the resulting strategies types are correct to avoid ClassCastException.

Type Parameters:

T - the array type

Parameters:

predicate - predicate to filter strategies using type T.

Returns:

collection of filtered strategies
