All Superinterfaces:
All Known Implementing Classes:
AbstractNumberField, BigDecimalField, EmailField, Input, IntegerField, NumberField, PasswordField, RichTextEditor, TextArea, TextField
public interface HasValueChangeMode extends SerializableDenotes that the component is able to change the way its value on the client side is synchronized with the server side.
A class implementing this interface should typically also implement
HasValueeven though this is not required on the API level.Since:
1.0.

Returns:
current value change mode of the component, or
nullif the value is not synchronized

setValueChangeMode
void setValueChangeMode(ValueChangeMode valueChangeMode)Sets new value change mode for the component.
Parameters:
valueChangeMode- new value change mode, ornullto disable the value synchronization
