Method Details

create

static <ENTITY> DoubleField<ENTITY> create(Class<ENTITY> table,
 String columnName,
 DoubleGetter<ENTITY> getter,
 boolean unique)

Creates a new DoubleField using the default implementation.

Type Parameters:

ENTITY - entity type

Parameters:

table - the table that the field belongs to

columnName - the name of the database column the field represents

getter - method reference to getter in entity

unique - if column only contains unique values

Returns:

the created field

applyAsDouble

default double applyAsDouble(ENTITY entity)

Specified by:

applyAsDouble in interface com.speedment.runtime.compute.ToDouble<ENTITY>

Specified by:

applyAsDouble in interface ToDoubleFunction<ENTITY>

comparator

DoubleFieldComparator<ENTITY> comparator()

Description copied from interface: HasComparableOperators

Returns a Comparator that will compare to this field using this fields natural order, null fields are sorted last.

Specified by:

comparator in interface HasComparableOperators<ENTITY,Double>

Returns:

a Comparator that will compare to this field using this fields natural order, null fields are sorted last.

reversed

default DoubleFieldComparator<ENTITY> reversed()

Description copied from interface: FieldComparator

Returns a new FieldComparator that order entities in the opposite orders compared to this comparator. For an example, if this comparator orders entities based on a column 'firstname' in descending order, then the returned FieldComparator will be ordering entities based on 'firstname' in ascending order.

Specified by:

reversed in interface Comparator<ENTITY>

Specified by:

reversed in interface DoubleFieldComparator<ENTITY>

Specified by:

reversed in interface FieldComparator<ENTITY>

Specified by:

reversed in interface HasComparableOperators<ENTITY,Double>

Returns:

a new reverse comparator

getField

default DoubleField<ENTITY> getField()

Description copied from interface: DoubleFieldComparator

Gets the field that is being compared.

Specified by:

getField in interface DoubleFieldComparator<ENTITY>

Specified by:

getField in interface FieldComparator<ENTITY>

Returns:

the compared field
