UIParameter is a UIComponent
that represents
an optionally named configuration parameter for a parent component.
Parent components should retrieve the value of a parameter by calling
getValue()
. In this way, the parameter value can be set
directly on the component (via setValue()
), or retrieved
indirectly via the value binding expression.
In some scenarios, it is necessary to provide a parameter name, in
addition to the parameter value that is accessible via the
getValue()
method.
Renderer
s that support parameter names on their
nested UIParameter
child components should document
their use of this property.

UIParameter
public UIParameter()

instance with default property values.

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 appropriateRenderer
for this component instance.- 规范说明:
getFamily
in classUIComponent
getName
public String getName()
Return the optional parameter name for this parameter.
setName
public void setName(String name)
Set the optional parameter name for this parameter.
- 参数:
name
- The new parameter name, ornull
for no name
getValue
public Object getValue()
Returns the
value
property of theUIParameter
.
setValue
public void setValue(Object value)
Sets the
value
property of the\UIParameter
.- 参数:
value
- the new value
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
- 规范说明:
saveState
in interfaceStateHolder
- 重写:
saveState
in classUIComponentBase
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 theStateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object)
method on all those instances as well.- 规范说明:
restoreState
in interfaceStateHolder
- 重写:
restoreState
in classUIComponentBase
