For example, it's used when calling PreparedStatement.setNull(int, int).

Specified by:

getJdbcTypeCode in interface JdbcType

Returns:

a JDBC type code

getElementJdbcType

public JdbcType getElementJdbcType()

getJdbcRecommendedJavaTypeMapping

public <T> JavaType<T> getJdbcRecommendedJavaTypeMapping(Integer precision,
 Integer scale,
 TypeConfiguration typeConfiguration)

Specified by:

getJdbcRecommendedJavaTypeMapping in interface JdbcType

getJdbcLiteralFormatter

public <T> JdbcLiteralFormatter<T> getJdbcLiteralFormatter(JavaType<T> javaTypeDescriptor)

Description copied from interface: JdbcType

Obtain a formatter object capable of rendering values of the given Java type as SQL literals of the type represented by this object.

Specified by:

getJdbcLiteralFormatter in interface JdbcType

getPreferredJavaTypeClass

public Class<?> getPreferredJavaTypeClass(WrapperOptions options)

Description copied from interface: JdbcType

The Java type class that is preferred by the binder or null.

Specified by:

getPreferredJavaTypeClass in interface JdbcType

getElementTypeName

protected String getElementTypeName(JavaType<?> javaType,
 SharedSessionContractImplementor session)
