  - getState
```
public CustomFieldState getState()
```
    Description copied from class: AbstractConnector
    
    Returns the shared state object for this connector. Override this method to define the shared state type for your connector.
    
    Specified by:
    
    getState in interface ComponentConnector
    
    Specified by:
    
    getState in interface ServerConnector
    
    Overrides:
    
    getState in class AbstractFieldConnector
    
    Returns:
    
    the current shared state (never null)
  - getWidget
```
public VCustomField getWidget()
```
    Description copied from class: AbstractComponentConnector
    
    Returns the widget associated with this paintable. The widget returned by this method must not changed during the life time of the paintable.
    
    Specified by:
    
    getWidget in interface HasWidget
    
    Overrides:
    
    getWidget in class AbstractComponentConnector
    
    Returns:
    
    The widget associated with this paintable
  - updateCaption
```
public void updateCaption(ComponentConnector connector)
```
    Description copied from interface: HasComponentsConnector
    
    Update child components caption, description and error message.
    Each component is responsible for maintaining its caption, description and error message. In most cases components doesn't want to do that and those elements reside outside of the component. Because of this layouts must provide service for it's childen to show those elements for them.
    
    Specified by:
    
    updateCaption in interface HasComponentsConnector
    
    Parameters:
    
    connector - Child component for which service is requested.
  - onStateChanged
```
public void onStateChanged(StateChangeEvent stateChangeEvent)
```
    Description copied from interface: StateChangeEvent.StateChangeHandler
    
    Notifies the event handler that the state has changed.
    
    Specified by:
    
    onStateChanged in interface StateChangeEvent.StateChangeHandler
    
    Overrides:
    
    onStateChanged in class AbstractComponentConnector
    
    Parameters:
    
    stateChangeEvent - the state change event with details about the change
  - onConnectorHierarchyChange
```
public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent event)
```
    Description copied from interface: ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler
    
    Called by the framework when the list of child components of the connector implementing this interface has changed. The implementation is responsible for attaching the widgets of any new children and detaching the widgets of any removed children. Implementations should typically also make sure that the child widgets are attached according to the ordering of the child components.
    This method is called after the shared state and hierarchy data (i.e. AbstractHasComponentsConnector.setChildComponents(List)) been updated for all affected connectors, but before updating captions, firing state change events, invoking updateFromUIDL for legacy connectors, invoking RPC and starting the layout phase.
    Please note that hierarchy change events are fired in a non-deterministic order when a message from the server causes multiple parts of the hierarchy to change. This means that the old parent connector might not yet have detached a child widget and that the widget of a removed child might already have been attached by its new parent.
    
    Specified by:
    
    onConnectorHierarchyChange in interface ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler
    
    Parameters:
    
    event - the event with information about the hierarchy change
  - getChildComponents
```
public List<ComponentConnector> getChildComponents()
```
    Description copied from interface: HasComponentsConnector
    
    Returns the child components for this connector.
    The children for this connector are defined as all HasComponentss whose parent is this HasComponentsConnector.
    Note that the method ServerConnector.getChildren() can return a larger list of children including both the child components and any extensions registered for the connector.
    
    Specified by:
    
    getChildComponents in interface HasComponentsConnector
    
    Returns:
    
    A collection of child components for this connector. An empty collection if there are no children. Never returns null.
  - setChildComponents
```
public void setChildComponents(List<ComponentConnector> childComponents)
```
    Description copied from interface: HasComponentsConnector
    
    Sets the children for this connector. This method should only be called by the framework to ensure that the connector hierarchy on the client side and the server side are in sync.
    Note that calling this method does not call ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler.onConnectorHierarchyChange(ConnectorHierarchyChangeEvent) . The event method is called only when the hierarchy has been updated for all connectors.
    Note that this method is separate from ServerConnector.setChildren(List) and contains only child components. Both methods are called separately by the framework if the connector implements HasComponentsConnector.
    
    Specified by:
    
    setChildComponents in interface HasComponentsConnector
    
    Parameters:
    
    childComponents - The new child connectors (components only)
  - addConnectorHierarchyChangeHandler
```
public com.google.gwt.event.shared.HandlerRegistration addConnectorHierarchyChangeHandler(ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler handler)
```
    Description copied from interface: HasComponentsConnector
    
    Adds a handler that is called whenever the child hierarchy of this connector has been updated by the server.
    
    Specified by:
    
    addConnectorHierarchyChangeHandler in interface HasComponentsConnector
    
    Parameters:
    
    handler - The handler that should be added.
    
    Returns:
    
    A handler registration reference that can be used to unregister the handler
  - getContent
```
protected ComponentConnector getContent()
```
    Returns the content (only/first child) of the container.
    
    Returns:
    
    child connector or null if none (e.g. invisible or not set on server)
  - getContentWidget
```
protected com.google.gwt.user.client.ui.Widget getContentWidget()
```
    Returns the widget (if any) of the content of the container.
    
    Returns:
    
    widget of the only/first connector of the container, null if no content or if there is no widget for the connector
