Method Details

getJdbcTypeCode

public int getJdbcTypeCode()

Description copied from interface: JdbcType

The JDBC type code used when interacting with JDBC APIs.

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

Specified by:

getJdbcTypeCode in interface JdbcType

Returns:

a JDBC type code

getDefaultSqlTypeCode

public int getDefaultSqlTypeCode()

Description copied from interface: JdbcType

A JDBC type code that identifies the SQL column type.

This value might be different from JdbcType.getDdlTypeCode() if the actual type e.g. JSON is emulated through a type like CLOB.

Specified by:

getDefaultSqlTypeCode in interface JdbcType

Returns:

a JDBC type code

toString

public String toString()

Overrides:

toString in class Object

getJdbcLiteralFormatter

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

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

resolveAggregateJdbcType

public AggregateJdbcType resolveAggregateJdbcType(EmbeddableMappingType mappingType,
 String sqlType,
 RuntimeModelCreationContext creationContext)

Specified by:

resolveAggregateJdbcType in interface AggregateJdbcType

getEmbeddableMappingType

public EmbeddableMappingType getEmbeddableMappingType()

Specified by:

getEmbeddableMappingType in interface AggregateJdbcType

fromString

protected <X> X fromString(String string,
 JavaType<X> javaType,
 WrapperOptions options)
                    throws SQLException

Throws:

SQLException

createJdbcValue

public Object createJdbcValue(Object domainValue,
 WrapperOptions options)
                       throws SQLException

Specified by:

createJdbcValue in interface AggregateJdbcType

Throws:

SQLException

extractJdbcValues

public Object[] extractJdbcValues(Object rawJdbcValue,
 WrapperOptions options)
                           throws SQLException

Specified by:

extractJdbcValues in interface AggregateJdbcType

Throws:

SQLException

toString

protected <X> String toString(X value,
 JavaType<X> javaType,
 WrapperOptions options)

getBinder

public <X> ValueBinder<X> getBinder(JavaType<X> javaType)

Description copied from interface: JdbcType

Obtain a binder object capable of binding values of the given Java type to parameters of a JDBC PreparedStatement.

Specified by:

getBinder in interface JdbcType

Parameters:

javaType - The descriptor describing the types of Java values to be bound

Returns:

The appropriate binder.

getExtractor

public <X> ValueExtractor<X> getExtractor(JavaType<X> javaType)

Description copied from interface: JdbcType

Obtain an extractor object capable of extracting values of the given Java type from a JDBC ResultSet.

Specified by:

getExtractor in interface JdbcType

Parameters:

javaType - The descriptor describing the types of Java values to be extracted

Returns:

The appropriate extractor
