public class UIMessage
extends UIComponentBase

This component is responsible for displaying messages for a specific UIComponent, identified by a clientId. The component obtains the messages from the FacesContext.

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


Field Summary
static java.lang.String COMPONENT_FAMILY

static java.lang.String COMPONENT_TYPE
          The standard component type for this component.
 
Constructor Summary
UIMessage()
          Create a new UIMessage instance with default property values.
 
Method Summary
 java.lang.String getFamily()
          Return the identifier of the component family to which this component belongs.
 java.lang.String getFor()
          Return the client identifier of the component for which this component represents associated message(s) (if any).
 boolean isShowDetail()
          Return the flag indicating whether the detail property of the associated message(s) should be displayed.
 boolean isShowSummary()
          Return the flag indicating whether the summary property of the associated message(s) should be displayed.
 void restoreState(FacesContext context, java.lang.Object state)
           Perform any processing required to restore the state from the entries in the state Object.
 java.lang.Object saveState(FacesContext context)
           Gets the state of the instance as a Serializable Object.
 void setFor(java.lang.String newFor)
          Set the client identifier of the component for which this component represents associated message(s) (if any).
 void setShowDetail(boolean showDetail)
          Set the flag indicating whether the detail property of the associated message(s) should be displayed.
 void setShowSummary(boolean showSummary)
          Set the flag indicating whether the summary property of the associated message(s) should be displayed.

Field Detail

COMPONENT_TYPE

public static final java.lang.String COMPONENT_TYPE

The standard component type for this component.

See Also:
Constant Field Values

COMPONENT_FAMILY

public static final java.lang.String COMPONENT_FAMILY

The standard component family for this component.

See Also:
Constant Field Values
Constructor Detail

UIMessage

public UIMessage()

Create a new UIMessage instance with default property values.

Method Detail

getFamily

public java.lang.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.

Specified by:
getFamily in class UIComponent

getFor

public java.lang.String getFor()

Return the client identifier of the component for which this component represents associated message(s) (if any).


setFor

public void setFor(java.lang.String newFor)

Set the client identifier of the component for which this component represents associated message(s) (if any). This property must be set before the message is displayed.

Parameters:
newFor - The new client id

isShowDetail

public boolean isShowDetail()

Return the flag indicating whether the detail property of the associated message(s) should be displayed. Defaults to true.


setShowDetail

public void setShowDetail(boolean showDetail)

Set the flag indicating whether the detail property of the associated message(s) should be displayed.

Parameters:
showDetail - The new flag

isShowSummary

public boolean isShowSummary()

Return the flag indicating whether the summary property of the associated message(s) should be displayed. Defaults to false.


setShowSummary

public void setShowSummary(boolean showSummary)

Set the flag indicating whether the summary property of the associated message(s) should be displayed.

Parameters:
showSummary - The new flag value

saveState

public java.lang.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 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

Specified by:
saveState in interface StateHolder
Overrides:
saveState in class UIComponentBase

restoreState

public void restoreState(FacesContext context,
                         java.lang.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 the StateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object) method on all those instances as well.

Specified by:
restoreState in interface StateHolder
Overrides:
restoreState in class UIComponentBase
