Method Detail

validate

public void validate(ValidatorContext context,
                     java.lang.Object beanToValidate)

Description copied from interface: Validator

This is the method that's called to validate the "bean-to-validate." Use the passed in ValidatorContext to report validation failures, etc. The passed-in "bean-to-validate" is the same instance returned from the call to constructBeanToValidate(), but with all of the appropriate properties set (based upon the configured mapping).

Parameters:

context - The ValidatorContext, which is used to report failures.

beanToValidate - The JavaBean to validate.

getDefaultFailure

public FailureMessage getDefaultFailure()

Retrieves the default failure message. If only one failure is used by the sub-class, then this property can be used to get the failure message for reporting a failure.

Overrides:

getDefaultFailure in class BaseValidator

Returns:

Returns the default failure message.

setDefaultFailure

public void setDefaultFailure(FailureMessage failure)

Sets the failure message. This is called based upon what's configured for this validator. Ensure that this is properly configured: otherwise, the call to getDefaultFailure() will return null.

Overrides:

setDefaultFailure in class BaseValidator

Parameters:

failure - The default failure message to use.
