Field Details

childElementTypeClass

protected final Class<T extends ModelElementInstance> childElementTypeClass

maxOccurs

protected int maxOccurs

the maximum count of child elements in the collection. An unbounded collection has a negative maxOccurs.

Constructor Details

ChildElementCollectionImpl

public ChildElementCollectionImpl(Class<T> childElementTypeClass,
 ModelElementTypeImpl parentElementType)

Method Details

setImmutable

public void setImmutable()

setMutable

public void setMutable(boolean isMutable)

isImmutable

public boolean isImmutable()

Description copied from interface: ChildElementCollection

Indicates whether the collection is immutable. If the collection is immutable, all state-altering operations such as Collection.add(Object) or Collection.remove(Object) will throw an UnsupportedOperationException.

Specified by:

isImmutable in interface ChildElementCollection<T extends ModelElementInstance>

Returns:

true if the collection is mutable, false otherwise.

getMinOccurs

public int getMinOccurs()

Description copied from interface: ChildElementCollection

Indicates the minimal element count of a collection. Returns a positive integer or '0'.

Specified by:

getMinOccurs in interface ChildElementCollection<T extends ModelElementInstance>

Returns:

the minimal element count of the collection.

setMinOccurs

public void setMinOccurs(int minOccurs)

getMaxOccurs

public int getMaxOccurs()

Description copied from interface: ChildElementCollection

Indicates the max element count of a collection. In a negative value is returned (like '-1'), the collection is unbounded.

Specified by:

getMaxOccurs in interface ChildElementCollection<T extends ModelElementInstance>

Returns:

the max element count for this collection.

getChildElementType

public ModelElementType getChildElementType(Model model)

Description copied from interface: ChildElementCollection

Get the model element type of the elements contained in this collection.

Specified by:

getChildElementType in interface ChildElementCollection<T extends ModelElementInstance>

Parameters:

model - the model of the element

Returns:

the containing ModelElementType

getChildElementTypeClass

public Class<T> getChildElementTypeClass()

Description copied from interface: ChildElementCollection

Get the class of the elements contained in this collection.

Specified by:

getChildElementTypeClass in interface ChildElementCollection<T extends ModelElementInstance>

Returns:

the class of contained types

getParentElementType

public ModelElementType getParentElementType()

Description copied from interface: ChildElementCollection

Get the model element type of the element owns the collection

Specified by:

getParentElementType in interface ChildElementCollection<T extends ModelElementInstance>

Returns:

the parent element of the collection

setMaxOccurs

public void setMaxOccurs(int maxOccurs)

get

public Collection<T> get(ModelElementInstance element)

Description copied from interface: ChildElementCollection

returns a Collection containing all or a subset of the child elements of a ModelElementInstance.

Specified by:

get in interface ChildElementCollection<T extends ModelElementInstance>
