Method Summary

Modifier and Type	Method	Description
void	add(Item item, E value)
ListField<E>	copy(CopyMapper mapper)
ListField<E>	copyWith(FunctionField<?> copyWith)	Returns a new ListField, that differs from this ListField by enforcing that parent and element items have the same value in the given field.
static <E> ListField<E>	create(FunctionField<E> element)
List<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).
<P extends Item> List<P>	getDistinctParents(Class<P> parentClass, E element)	Returns the items, for which this field list contains the given element.
FunctionField<E>	getElement()
IntegerField	getOrder()
ItemField<?>	getParent()
<P extends Item> ItemField<P>	getParent(Class<P> parentClass)
Query<E>	getQuery(Item item)	Returns the query that is used to implement get(Item).
Type<?>	getRelationType()
UniqueConstraint	getUniqueConstraint()
static <E> ListField<E>	newList(FunctionField<E> element)	Deprecated. Use create(FunctionField) instead
protected void	onMount()	Here you can do additional initialization not yet done in the constructor.
boolean	removeAll(Item item, E element)
void	set(Item item, Collection<? extends E> value)

Method Details

create

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

copy

public ListField<E> copy(CopyMapper mapper)

Specified by:

copy in interface Copyable

copyWith

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

Returns a new ListField, that differs from this ListField 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()

getOrder

public IntegerField getOrder()

getUniqueConstraint

public UniqueConstraint getUniqueConstraint()

getElement

public FunctionField<E> getElement()

Specified by:

getElement in class AbstractListField<E>

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 ListField's type.

IllegalStateException - if there is no CopyConstraint on the given field

get

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

Specified by:

get in class AbstractListField<E>

See Also:

• getQuery(Item)

getQuery

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

Returns the query that is used to implement get(Item).

getDistinctParents

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

Returns the items, for which this field list contains the given element. The result does not contain any duplicates, even if the element is contained in this field list for an item more than once. The order of the result is unspecified.

add

public void add(@Nonnull
 Item item,
 E value)

removeAll

public boolean removeAll(@Nonnull
 Item item,
 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)

Specified by:

set in class AbstractListField<E>

newList

@Deprecated
public static <E> ListField<E> newList(FunctionField<E> element)

Deprecated.

Use create(FunctionField) instead
