/**
* Build a Hibernate Type that incorporates the JPA AttributeConverter. AttributeConverter works totally in
* memory, meaning it converts between one Java representation (the entity attribute representation) and another
* (the value bound into JDBC statements or extracted from results). However, the Hibernate Type system operates
* at the lower level of actually dealing directly with those JDBC objects. So even though we have an
* AttributeConverter, we still need to "fill out" the rest of the BasicType data and bridge calls
* to bind/extract through the converter.
*
* Essentially the idea here is that an intermediate Java type needs to be used. Let's use an example as a means
* to illustrate... Consider an {@code AttributeConverter}. This tells Hibernate that the domain
* model defines this attribute as an Integer value (the 'entityAttributeJavaType'), but that we need to treat the
* value as a String (the 'databaseColumnJavaType') when dealing with JDBC (aka, the database type is a
* VARCHAR/CHAR):
* -
* When binding values to PreparedStatements we need to convert the Integer value from the entity
* into a String and pass that String to setString. The conversion is handled by calling
* {@link AttributeConverter#convertToDatabaseColumn(Object)}
*
* -
* When extracting values from ResultSets (or CallableStatement parameters) we need to handle the
* value via getString, and convert that returned String to an Integer. That conversion is handled
* by calling {@link AttributeConverter#convertToEntityAttribute(Object)}
*
*
*
