Method Detail

passRule

boolean passRule(T item)

Determines whether an item passes a validation rule.

Parameters:

item - Item to validate

java.lang.String failMessage()

Returns the message when an item fails to pass this rule.

Returns:

Validation failure message

setFailMessage

void setFailMessage(java.lang.String msg)

Changes this rule's failure message. Normally the failure rule set via BaseRule.BaseRule(String) suffices for the rule. However, on occasion a rule will wish to customize the failure message at runtime. In that situation, the passRule(Object) implementation calls this method.
