- Method Detail
  - getComponent
```
com.vaadin.flow.component.Component getComponent()
```
    Get the UI Component which represents this object.
    
    Returns:
    
    the UI component (not null)
  - getElement
```
default com.vaadin.flow.dom.Element getElement()
```
    Specified by:
    
    getElement in interface com.vaadin.flow.component.HasElement
  - setVisible
```
default void setVisible(boolean visible)
```
    Sets the component visibility value.
    When a component is set as invisible, all the updates of the component from the server to the client are blocked until the component is set as visible again.
    Invisible components don't receive any updates from the client-side. Unlike the server-side updates, client-side updates, if any, are discarded while the component is invisible, and are not transmitted to the server when the component is made visible.
    
    Parameters:
    
    visible - the component visibility value
  - isVisible
```
default boolean isVisible()
```
    Gets the component visibility value.
    
    Returns:
    
    true if the component is visible, false otherwise
