BasicValueConverter (Hibernate Javadocs)

Type Parameters:

D - The Java type we use to represent the domain (object) type

R - The Java type we use to represent the relational type

All Known Subinterfaces:

EnumValueConverter<O,R>, JpaAttributeConverter<O,R>

All Known Implementing Classes:

ArrayConverter, CharBooleanConverter, CollectionConverter, DiscriminatorConverter, JpaAttributeConverterImpl, NamedEnumValueConverter, NumericBooleanConverter, OrdinalEnumValueConverter, TrueFalseConverter, YesNoConverter
```
@Incubating
public interface BasicValueConverter<D,R>
```
Support for basic-typed value conversions.
Conversions might be determined by:
- a custom JPA AttributeConverter, or
- implicitly, based on the Java type, for example, for Java enums.

```
@Incubating
default String getCheckCondition(String columnName,
                                 JdbcType sqlType,
                                 Dialect dialect)
```
    The check constraint that should be added to the column definition in generated DDL.
    
    Parameters:
    
    columnName - the name of the column
    
    sqlType - the JdbcType of the mapped column
    
    dialect - the SQL Dialect
    
    Returns:
    
    a check constraint condition or null
  - getSpecializedTypeDeclaration
```
@Incubating
default String getSpecializedTypeDeclaration(JdbcType jdbcType,
                                             Dialect dialect)
