Enum PushMode

DISABLED

public static final PushMode DISABLED

Push is disabled. Regular AJAX requests are used to communicate between the client and the server. Asynchronous messages from the server are not possible. ui.push() throws IllegalStateException.

This is the default mode unless configured otherwise.

MANUAL

public static final PushMode MANUAL

Push is enabled. A bidirectional channel is established between the client and server and used to communicate state changes and RPC invocations. The client is not automatically updated if the server-side state is asynchronously changed; ui.push() must be explicitly called.

values

public static PushMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PushMode valueOf​(String name)

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
