Method Detail

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

getDefaultSqlTypeCode

public abstract 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

getConstructorFunction

protected abstract String getConstructorFunction()

appendWriteExpression

public void appendWriteExpression(String writeExpression,
                                  SqlAppender appender,
                                  Dialect dialect)

Description copied from interface: JdbcType

Append the write expression wrapped in a way to be able to write values with this JdbcType's ValueBinder.

Specified by:

appendWriteExpression in interface JdbcType

toGeometry

public org.geolatte.geom.Geometry<?> toGeometry(String wkt)

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

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
