Constructor Detail

DelegatingValidatorContext

public DelegatingValidatorContext(ValidationAware validationAware,
                                  TextProvider textProvider,
                                  LocaleProvider localeProvider)

Creates a new validation context given a ValidationAware object, and a text and locale provider. These objects are used internally to set errors and get and set error text.

DelegatingValidatorContext

public DelegatingValidatorContext(Object object)

Creates a new validation context given an object - usually an Action. The internal objects (validation aware instance and a locale and text provider) are created based on the given action.

Parameters:

object - the object to use for validation (usually an Action).

DelegatingValidatorContext

public DelegatingValidatorContext(Class clazz)

Create a new validation context given a Class definition. The locale provider, text provider and the validation context are created based on the class.

Parameters:

clazz - the class to initialize the context with.
