Method Summary

Modifier and Type	Method	Description
default char	applyAsChar(ENTITY entity)
CharFieldComparator<ENTITY>	comparator()	Returns a Comparator that will compare to this field using this fields natural order, null fields are sorted last.
static <ENTITY> CharField<ENTITY>	create(Class<ENTITY> table, String columnName, CharGetter<ENTITY> getter, boolean unique)	Creates a new CharField using the default implementation.
default CharField<ENTITY>	getField()	Gets the field that is being compared.

Method Details

create

static <ENTITY> CharField<ENTITY> create(Class<ENTITY> table,
 String columnName,
 CharGetter<ENTITY> getter,
 boolean unique)

Creates a new CharField 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

applyAsChar

default char applyAsChar(ENTITY entity)

Specified by:

applyAsChar in interface com.speedment.common.function.ToCharFunction<ENTITY>

comparator

CharFieldComparator<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,Character>

Returns:

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

reversed

default CharFieldComparator<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 CharFieldComparator<ENTITY>

Specified by:

reversed in interface Comparator<ENTITY>

Specified by:

reversed in interface FieldComparator<ENTITY>

Specified by:

reversed in interface HasComparableOperators<ENTITY,Character>

Returns:

a new reverse comparator

getField

default CharField<ENTITY> getField()

Description copied from interface: CharFieldComparator

Gets the field that is being compared.

Specified by:

getField in interface CharFieldComparator<ENTITY>

Specified by:

getField in interface FieldComparator<ENTITY>

Returns:

the compared field
