Method Detail

validate

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

Validates that the supplied value represents a valid number that adheres to the Modulo-11 check.
In the following cases, no validation will take place:

• The supplied component is not of type UIInput
• The supplied value is null or empty

Note: A missing value (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.

value - The value that needs to be validated.

Throws:

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

javax.faces.validator.ValidatorException - When the supplied value does not represent a valid modulo-11 value.
