setFunctionName

public void setFunctionName(String functionName)

Set the value of the functionName property.

Parameters:

functionName - The new function name

restoreState

public void restoreState(javax.faces.context.FacesContext context,
                         Object state)

Restore the state of this component.

Specified by:

restoreState in interface javax.faces.component.StateHolder

Overrides:

restoreState in class javax.faces.component.UIComponentBase

Parameters:

context - FacesContext for the current request

state - State to be restored

saveState

public Object saveState(javax.faces.context.FacesContext context)

Save the state of this component.

Specified by:

saveState in interface javax.faces.component.StateHolder

Overrides:

saveState in class javax.faces.component.UIComponentBase

Parameters:

context - FacesContext for the current request

Returns:

component's state

writeJavaScriptParams

public void writeJavaScriptParams(javax.faces.context.ResponseWriter writer,
                                  javax.faces.context.FacesContext context,
                                  String id,
                                  CommonsValidator v)
