Get the state of the control

Used to remember the current state of the control. For example, SwatEntry implements this method to return its $value property, but can return any variable type, including array, that represents the control's current state. Sub-classes should override and implement this method to store their state.

Returns:

The current state of the control.

Set the state of the control

Used to set the current state of the control back to a stored state. This implementation of this method should correspond to the implementation of getState(). Sub-classes should override and implement this method to store their state.

Parameters:

state - The state to load into the control.
