Method Detail

validate

public void validate(javax.faces.context.FacesContext facesContext,
                     javax.faces.component.UIComponent component,
                     Object giro)

In the following cases, no validation will take place:

• The supplied component is not of type UIComponent
• The supplied giro is null or empty

Note: A missing giro (null or empty) is not handled by this validator since it should be handled by the required attribute of the component.

Parameters:

facesContext - The FacesContext.

component - The component that needs to be validated.

giro - The giro account number that needs to be validated.

Throws:

NullPointerException - When either the supplied facesContext or component is null.
