public interface JavalidExtensionLookup
extends JavalidExtension

This extension interface is required by extensions that support some kind of lookup and/or validation. Generally its only used by extensions that ship with JaValid. Likely you don't need this interface at all but its parent instead.

java.lang.Object	lookupBean(java.lang.String name) Based on given name attempts to lookup a bean.
java.util.List<ValidationMessage>	validate(java.lang.Object currentInstance, java.lang.String prefixPath, java.lang.String beanNameExpression, JvMethod jvMethod) This method is called by the JV framework if an object to validate has defined a lookup and thus must be validated through a bean.

Method Detail

lookupBean

java.lang.Object lookupBean(java.lang.String name)

Based on given name attempts to lookup a bean. Implementors must raise a JavalidLookupFailedException if the bean was NOT found. If the bean was found, but null, simply return null.

Parameters:

name - The name to lookup

Returns:

The Object found (even if its null), if not found raise JavalidLookupException

validate

java.util.List<ValidationMessage> validate(java.lang.Object currentInstance,
                                           java.lang.String prefixPath,
                                           java.lang.String beanNameExpression,
                                           JvMethod jvMethod)

This method is called by the JV framework if an object to validate has defined a lookup and thus must be validated through a bean. It is the developer's responsibility to provide JvMethod with parameters that are needed. Think of: Object value and String prefixPath. These can be specified in a JvParam (see docs)

Parameters:

currentInstance - The current instance for validation

prefixPath - The prefix path for this instance

beanNameExpression - The name of the spring bean to use

jvMethod - The method containing the actual call to be performed on the bean with ALL needed parameters.

Returns:

List containing ValidationMesssage instances if errors were encountered, if no errors an empty list must be returned.
