Method Summary

Modifier and Type	Method	Description
boolean	add(Item item, E element)
SetField<E>	copy(CopyMapper mapper)
SetField<E>	copyWith(FunctionField<?> copyWith)	Returns a new SetField, that differs from this SetField by enforcing that parent and element items have the same value in the given field.
static <E> SetField<E>	create(FunctionField<E> element)
Set<E>	get(Item item)
<T> FunctionField<T>	getCopyWithCopyField(FunctionField<T> template)	Get the field that stores a redudant copy of a parent item's value at the relation item, to enforce a CopyConstraint added with copyWith(FunctionField).
List<FunctionField<?>>	getCopyWithTemplateFields()	Get the template fields added with copyWith(FunctionField).
FunctionField<E>	getElement()
IntegerField	getOrder()
ItemField<?>	getParent()
<P extends Item> ItemField<P>	getParent(Class<P> parentClass)
<P extends Item> List<P>	getParents(Class<P> parentClass, E element)	Returns the items, for which this field set contains the given element.
Query<E>	getQuery(Item item)
Type<?>	getRelationType()
UniqueConstraint	getUniqueConstraint()
UniqueConstraint	getUniqueConstraintForOrder()
boolean	isOrdered()	Returns whether this SetField is ordered.
static <E> SetField<E>	newSet(FunctionField<E> element)	Deprecated. Use create(FunctionField) instead
protected void	onMount()	Here you can do additional initialization not yet done in the constructor.
SetField<E>	ordered()	Returns a new SetField, that differs from this SetField by being ordered.
boolean	remove(Item item, E element)
void	set(Item item, Collection<? extends E> value)
void	setAndCast(Item item, Collection<?> value)

Method Details

create

public static <E> SetField<E> create(FunctionField<E> element)

copy

public SetField<E> copy(CopyMapper mapper)

Specified by:

copy in interface Copyable

ordered

public SetField<E> ordered()

Returns a new SetField, that differs from this SetField by being ordered.

copyWith

public SetField<E> copyWith(FunctionField<?> copyWith)

Returns a new SetField, that differs from this SetField by enforcing that parent and element items have the same value in the given field.

Throws:

IllegalStateException - if the element field is not an ItemField

IllegalArgumentException - if the field given as parameter is not final

onMount

protected void onMount()

Description copied from class: Pattern

Here you can do additional initialization not yet done in the constructor. In this method you can call methods Pattern.getType() and Feature.getName() for the first time.

Overrides:

onMount in class Pattern

getParent

@Nonnull
public <P extends Item> ItemField<P> getParent(@Nonnull
 Class<P> parentClass)

getParent

public ItemField<?> getParent()

isOrdered

public boolean isOrdered()

Returns whether this SetField is ordered. An ordered SetField maintains the insertion order of its elements.

getOrder

public IntegerField getOrder()

getUniqueConstraintForOrder

public UniqueConstraint getUniqueConstraintForOrder()

getElement

public FunctionField<E> getElement()

getUniqueConstraint

public UniqueConstraint getUniqueConstraint()

getRelationType

public Type<?> getRelationType()

getCopyWithTemplateFields

public List<FunctionField<?>> getCopyWithTemplateFields()

Get the template fields added with copyWith(FunctionField).

getCopyWithCopyField

@Nonnull
public <T> FunctionField<T> getCopyWithCopyField(FunctionField<T> template)

Get the field that stores a redudant copy of a parent item's value at the relation item, to enforce a CopyConstraint added with copyWith(FunctionField).

Throws:

IllegalArgumentException - if the field given as parameter does not belong to this SetField's type.

IllegalStateException - if there is no CopyConstraint on the given field

get

@Nonnull
public Set<E> get(@Nonnull
 Item item)

getQuery

@Nonnull
public Query<E> getQuery(@Nonnull
 Item item)

getParents

@Nonnull
public <P extends Item> List<P> getParents(@Nonnull
 Class<P> parentClass,
 @Nonnull
 E element)

Returns the items, for which this field set contains the given element. The order of the result is unspecified.

add

public boolean add(@Nonnull
 Item item,
 @Nonnull
 E element)

Returns:

true if the result of get(Item) changed as a result of the call.

remove

public boolean remove(@Nonnull
 Item item,
 @Nonnull
 E element)

Returns:

true if the result of get(Item) changed as a result of the call.

set

public void set(@Nonnull
 Item item,
 @Nonnull
 Collection<? extends E> value)

setAndCast

public void setAndCast(Item item,
 Collection<?> value)

newSet

@Deprecated
public static <E> SetField<E> newSet(FunctionField<E> element)

Deprecated.

Use create(FunctionField) instead
