public class UISelectItems extends UIComponentBase
UISelectItems is a component that may be nested
inside a UISelectMany
or UISelectOne
component, and
causes the addition of one or more SelectItem
instances to the
list of available options in the parent component. The
value
of this component (set either directly, or acquired
indirectly a ValueExpression
, can be of any
of the following types:
SelectItem
- This instance is
added to the set of available options for the parent tag.SelectItem
- This set of instances is
added to the set of available options for the parent component,
in ascending subscript order.SelectItem
- This set of instances is
added to the set of available options for the parent component,
in the order provided by an iterator over them.SelectItem
instances that will
be constructed dynamically and added to the set of available options
for the parent component, in the order provided by an iterator over
the keys.Modifier and Type | Field and Description |

UIComponent
Return the identifier of the component family to which this

of the rendererType
property, may be used to select

StateHolder
Gets the state of the instance as a

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

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

with event handlers, validators, etc.)
this method must call the StateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object)
method on all those
