Method Detail

toString

public String toString(IFormComponent field,
                       Object value)

Description copied from interface: IValidator

Invoked during rendering to convert an object value (which may be null) to a String. It is acceptible to return null. The string will be the VALUE attribute of the HTML text field.

toObject

public Object toObject(IFormComponent field,
                       String value)
                throws ValidatorException

Description copied from interface: IValidator

Converts input, submitted by the client, into an object value. May return null if the input is null (and the required flag is false).

The input string will already have been trimmed. It may be null.

Throws:

ValidatorException - if the string cannot be converted into an object, or the object is not valid (due to other constraints).

renderValidatorContribution

public void renderValidatorContribution(IFormComponent field,
                                        IMarkupWriter writer,
                                        IRequestCycle cycle)

Description copied from class: BaseValidator

This implementation does nothing. Subclasses may supply their own implementation.
