Constructor Detail

DefaultTypeManager

public DefaultTypeManager(ServerConfig config,
                          BootupClasses bootupClasses)

Create the DefaultTypeManager.

Method Detail

add

public void add(ScalarType<?> scalarType)

Register a custom ScalarType.

Specified by:

add in interface TypeManager

addEnumType

public void addEnumType(ScalarType<?> scalarType,
                        Class<? extends Enum> enumClass)

Register the ScalarType for an enum. This is special in the sense that an Enum can have many classes if it uses method overrides and we need to register all the variations/classes for the enum.

Specified by:

addEnumType in interface TypeManager

getScalarType

public ScalarType<?> getScalarType(String cast)

Description copied from interface: TypeManager

Return the scalar type for the given logical type.

Specified by:

getScalarType in interface TypeManager

getScalarType

public ScalarType<?> getScalarType(int jdbcType)

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

Specified by:

getScalarType in interface TypeManager

Parameters:

jdbcType - as per java.sql.Types

getScalarType

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

This can return null if no matching ScalarType is found.

Specified by:

getScalarType in interface TypeManager

getDbMapScalarType

public ScalarType<?> getDbMapScalarType()

Description copied from interface: TypeManager

Return the ScalarType used to handle HSTORE (Map).

Specified by:

getDbMapScalarType in interface TypeManager

getArrayScalarType

public ScalarType<?> getArrayScalarType(Class<?> type,
                                        io.ebean.annotation.DbArray dbArray,
                                        Type genericType,
                                        boolean nullable)

Description copied from interface: TypeManager

Return the ScalarType used to handle DB ARRAY.

Specified by:

getArrayScalarType in interface TypeManager

getJsonScalarType

public ScalarType<?> getJsonScalarType(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:

getJsonScalarType in interface TypeManager

getScalarType

public ScalarType<?> getScalarType(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:

getScalarType 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.

createEnumScalarType

public ScalarType<?> createEnumScalarType(Class<? extends Enum<?>> enumType,
                                          javax.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:

createEnumScalarType in interface TypeManager
