Method Detail

getLabel

public String getLabel()

Description copied from interface: TypeMapper

Returns the label for this mapper that should appear to the end user.

Specified by:

getLabel in interface TypeMapper<T,T>

Returns:

the label

getJavaType

public Type getJavaType(Column column)

Description copied from interface: TypeMapper

Returns a type describing the resulting java type when this mapper is applied to a database result.

Specified by:

getJavaType in interface TypeMapper<T,T>

Parameters:

column - the column that is being mapped

Returns:

the resulting java type

toJavaType

public T toJavaType(Column column,
                    Class<?> entityType,
                    T value)

Description copied from interface: TypeMapper

Converts a value from the database domain to the java domain.

Specified by:

toJavaType in interface TypeMapper<T,T>

Parameters:

column - the column that is being mapped

entityType - the entity type that the mapping is for

value - the value to convert

Returns:

the converted value

toDatabaseType

public T toDatabaseType(T value)

Description copied from interface: TypeMapper

Converts a value from the java domain to the database domain.

Specified by:

toDatabaseType in interface TypeMapper<T,T>

Parameters:

value - the value to convert

Returns:

the converted value

getOrdering

public TypeMapper.Ordering getOrdering()

Description copied from interface: TypeMapper

Returns how the TypeMapper.Ordering of mapped and un-mapped types relate to each other.

Speedment is using this method to determine if certain optimizations of streams can be made. Make sure to implicitly specify the Ordering in any custom TypeMapper to allow maximum execution speed.

Specifying TypeMapper.Ordering.UNSPECIFIED prevents some optimizations so if possible, write a TypeMapper that RETAINS ordering.

Specified by:

getOrdering in interface TypeMapper<T,T>

Returns:

the ordering
