java.lang.Object javax.faces.component.UIComponent javax.faces.component.UIComponentBase javax.faces.component.UIOutput javax.faces.component.UIInput javax.faces.component.html.HtmlInputHidden
- All Implemented Interfaces:
- EditableValueHolder, StateHolder, ValueHolder
public class HtmlInputHidden
- extends UIInput
表示类型为 hidden
的 HTML input
元素。
默认情况下,rendererType
属性必须设置为 "javax.faces.Hidden
"。可以调用 setRendererType()
方法更改此值。
Represents an HTML input
element

.
By default, the rendererType
property must be set to "javax.faces.Hidden
".
This value can be changed by calling the setRendererType()
method.

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 theStateHolder.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 theStateManager
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 interfaceStateHolder
- Overrides:

- 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 theStateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object)
method on all those instances as well.- Specified by:
restoreState
