Method Summary

void	validatePropertyValues(PropertyValues pvs) Are these PropertyValues invalid?

Method Detail

validatePropertyValues

public void validatePropertyValues(PropertyValues pvs)
                            throws InvalidPropertyValuesException

Are these PropertyValues invalid? For example, are required properties missing? Does the presence of a particular property require others to be present? Implementations can rely on the contains() method of the PropertyValues interface, but cannot assume anything about the type of properties: type conversion is done only later, when PropertyValues are applied to a bean using a BeanWrapper object.

Parameters:

pvs - PropertyValues to validate

Throws:

InvalidPropertyValuesException - if the PropertyValues object is invalid
