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:

• Single instance of SelectItem - This instance is added to the set of available options for the parent tag.
• Array of SelectItem - This set of instances is added to the set of available options for the parent component, in ascending subscript order.
• Collection of 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.
• Map - The keys of this object (once converted to Strings) are assumed to be labels, and the values of this object (once converted to Strings) are assumed to be values, of 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.

Constructor Details

UISelectItems

public UISelectItems()

Create a new UISelectItems instance with default property values.

Method Details

setValueExpression

public void setValueExpression(String name,
 ValueExpression binding)

Overrides:

setValueExpression in class UIComponent

Parameters:

name - Name of the attribute or property for which to set a ValueExpression

binding - The ValueExpression to set, or null to remove any currently set ValueExpression

Throws:

IllegalArgumentException - If name is one of id, parent, or var.

NullPointerException - if name is null

getFamily

public String getFamily()

Description copied from class: UIComponent

Return the identifier of the component family to which this component belongs. This identifier, in conjunction with the value of the rendererType property, may be used to select the appropriate Renderer for this component instance. Note this method should NOT return null

Specified by:

getFamily in class UIComponent

Returns:

the component family (not null).

getValue

public Object getValue()

Returns the value property of the UISelectItems.

Returns:

the value.

setValue

public void setValue(Object value)

Sets the value property of the UISelectItems.

Parameters:

value - the new value
