UIOutput is a UIComponent that has a value, optionally retrieved from a model tier bean via a value expression, that is displayed to the user. The user cannot directly modify the rendered value; it is for display purposes only.

During the Render Response phase of the request processing lifecycle, the current value of this component must be converted to a String (if it is not already), according to the following rules:

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

restoreStateback to summary
public void restoreState(FacesContext context, Object state)

Overrides javax.faces.component.UIComponentBase.restoreState.

Implements javax.faces.component.StateHolder.restoreState.

Doc from javax.faces.component.StateHolder.restoreState.

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 restoreState method on all those instances as well.

If the state argument is null, take no action and return.

Parameters
context:FacesContext

the Faces context.

state:Object

the state.

public Object saveState(FacesContext context)

Overrides javax.faces.component.UIComponentBase.saveState.

Implements javax.faces.component.StateHolder.saveState.

Doc from javax.faces.component.StateHolder.saveState.

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 saveState method on all those instances as well. This method must not save the state of children and facets. That is done via the javax.faces.application.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

Parameters
context:FacesContext

the Faces context.

Returns:Object

the saved state.

public void setConverter(Converter<T> converter)

Implements javax.faces.component.ValueHolder.setConverter.

Set the Converter (if any) that is registered for this UIComponent.

Parameters
converter:Converter<T>

New Converter (or null)

Annotations
@Override

public void setValue(Object value)

Implements javax.faces.component.ValueHolder.setValue.

Doc from javax.faces.component.ValueHolder.setValue.

Set the value of this UIComponent (if any).
