public interface DiscriminatorMapping extends VirtualModelPart, BasicValuedModelPart, Fetchable
Mapping of a discriminator, for either entity or association (ANY) discrimination. Represents a composition of- a converter between the domain and relational form
- a JDBC mapping to read and write the relational values

Method Detail
-
getValueConverter
DiscriminatorConverter<?,?> getValueConverter()
Information about the value mappings
-
getUnderlyingJdbcMapping
JdbcMapping getUnderlyingJdbcMapping()
-
getDomainJavaType
default JavaType<?> getDomainJavaType()
The domain Java form, which is eitherJavaType<Class>
(entity class) orJavaType<String>
(entity name).
-
getRelationalJavaType
default JavaType<?> getRelationalJavaType()
The relational Java form. This will typically be some form of integer or character value.
-
resolveSqlExpression
Expression resolveSqlExpression(NavigablePath navigablePath, JdbcMapping jdbcMappingToUse, TableGroup tableGroup, SqlAstCreationState creationState)
Create the appropriate SQL expression for this discriminator- Parameters:
jdbcMappingToUse
- The JDBC mapping to use. This allows opting between the "domain result type" (aka Class) and the "underlying type" (Integer, String, etc)
