public Object saveState(FacesContext _context)
英文文档:

saveState

public Object saveState(FacesContext _context)
Description copied from interface: StateHolder

Gets the state of the instance as a Serializable Object.

If the class that implements this interface has references to instances that implement StateHolder (such as a UIComponent with event handlers, validators, etc.) this method must call the StateHolder.saveState(javax.faces.context.FacesContext) method on all those instances as well. This method must not save the state of children and facets. That is done via the StateManager

This method must not alter the state of the implementing object. In other words, after executing this code:

 Object state = component.saveState(facesContext);
 

component should be the same as before executing it.

The return from this method must be Serializable

Specified by:
saveState in interface StateHolder
Overrides:
saveState in class UIComponentBase

public void restoreState(FacesContext _context, Object _state)
英文文档:

restoreState

public void restoreState(FacesContext _context,
                         Object _state)
Description copied from interface: StateHolder

Perform any processing required to restore the state from the entries in the state Object.

If the class that implements this interface has references to instances that also implement StateHolder (such as a UIComponent with event handlers, validators, etc.) this method must call the StateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object) method on all those instances as well.

Specified by:
restoreState in interface StateHolder
Overrides:
restoreState in class UIComponentBase
