Interface PopulateValueRequestValidator

All Known Implementing Classes:

BasicFieldTypeValidator

public interface PopulateValueRequestValidator

This is injected into the BasicPersistenceModule and invoked prior to any attempts to actually populate values from the Entity DTO representation into the Hibernate entity using the FieldPersistenceProvider paradigm.

An example validator would ensure that Booleans are actually booleans, integers are actually integers, etc. since all values come in as Strings by default
