Method Detail

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:

Types.DOUBLE

getDdlTypeCode

public int getDdlTypeCode()

Description copied from interface: JdbcType

A JDBC type code that identifies the SQL column type to be used for schema generation.

This value is passed to DdlTypeRegistry.getTypeName(int, Size) to obtain the SQL column type.

Specified by:

getDdlTypeCode in interface JdbcType

Returns:

Types.FLOAT for schema generation

getCastType

public CastType getCastType()

Specified by:

getCastType in interface JdbcType

getFriendlyName

public String getFriendlyName()

Description copied from interface: JdbcType

A "friendly" name for use in logging

Specified by:

getFriendlyName in interface JdbcType

toString

public String toString()

Overrides:

toString in class Object

getJdbcRecommendedJavaTypeMapping

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

Specified by:

getJdbcRecommendedJavaTypeMapping in interface JdbcType

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

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

getBinder

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

Description copied from 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
