DefaultTypeManager

public DefaultTypeManager(DatabaseBuilder.Settings config,
 BootupClasses bootupClasses)

Create the DefaultTypeManager.

Method Details

type

public ScalarType<?> type(String cast)

Description copied from interface: TypeManager

Return the scalar type for the given logical type.

Specified by:

type in interface TypeManager

type

public ScalarType<?> type(int jdbcType)

Return the ScalarType for the given jdbc type as per java.sql.Types.

Specified by:

type in interface TypeManager

Parameters:

jdbcType - as per java.sql.Types

type

public ScalarType<?> type(Type propertyType,
 Class<?> propertyClass)

Description copied from interface: TypeManager

Find and return the ScalarType taking into account the property type with generics.

For example Array based ScalarType for types like List<String>.

Specified by:

type in interface TypeManager

type

public ScalarType<?> type(Class<?> type)

This can return null if no matching ScalarType is found.

Specified by:

type in interface TypeManager

geoTypeBinder

public GeoTypeBinder geoTypeBinder()

Description copied from interface: TypeManager

Return the Geometry type binder if provided.

Specified by:

geoTypeBinder in interface TypeManager

dbMapType

public ScalarType<?> dbMapType()

Description copied from interface: TypeManager

Return the ScalarType used to handle HSTORE (Mapinvalid input: '<'String,String>).

Specified by:

dbMapType in interface TypeManager

dbArrayType

public ScalarType<?> dbArrayType(Class<?> type,
 Type genericType,
 boolean nullable)

Description copied from interface: TypeManager

Return the ScalarType used to handle DB ARRAY.

Specified by:

dbArrayType in interface TypeManager

dbJsonType

public ScalarType<?> dbJsonType(DeployBeanProperty prop,
 int dbType,
 int dbLength)

Description copied from interface: TypeManager

Return the ScalarType used to handle JSON content.

Note that type expected to be JsonNode or Map.

Specified by:

dbJsonType in interface TypeManager

type

public ScalarType<?> type(Class<?> type,
 int jdbcType)

Return a ScalarType for a given class.

Used for java.util.Date and java.util.Calendar which can be mapped to different jdbcTypes in a single system.

Specified by:

type in interface TypeManager

convert

public Object convert(Object value,
 int toJdbcType)

Convert the Object to the required datatype. The

Parameters:

value - the Object value

toJdbcType - the type as per java.sql.Types.

enumType

public ScalarType<?> enumType(Class<? extends Enum<?>> enumType,
 jakarta.persistence.EnumType type)

Create a ScalarType for an Enum that has additional mapping.

The reason for this is that often in a DB there will be short codes used such as A,I,N rather than the ACTIVE, INACTIVE, NEW. So there really needs to be a mapping from the nicely named enumeration values to the typically much shorter codes used in the DB.

Specified by:

enumType in interface TypeManager
