Validates objects using Hibernate Validator.

Parameters:

content - an object to be validated

Returns:

a list of error messages or empty if object is valid

validateObject

public static String[] validateObject(App app,
                                      ParaObject content)

Returns:

a list of error messages or empty if object is valid

getCoreValidationConstraints

public static Map<String,Map<String,Map<String,Map<String,?>>>> getCoreValidationConstraints()
