The ElementGroupPrototype type exposes the following members.

Constructors

	Name	Description
	ElementGroupPrototype(ElementGroup, IEnumerable<ModelElement>)	Constructor
	ElementGroupPrototype(Partition, Guid)	Constructor for taking a rool domain class Id. This is used to determine whether an element can be merged under an parent element.
	ElementGroupPrototype(Partition, ICollection<ModelElement>, ElementGroup)	Constructor

Methods

	Name	Description
	CanCreateElementGroup(Partition)	Can this prototype element group create a clone of the progenitor element group in the indicated partition?
	CanCreateElementGroup(Store)	Can this prototype element group create a clone of the progenitor element group in the indicated store?
	CanCreateElementGroup(Partition, IElementPartitionMapper)	Can this prototype element group create a clone of the progenitor element group in the indicated partition?
	CreateElementGroup(Partition)	Create a clone of the progenitor element group
	CreateElementGroup(Store)	Create a clone of the progenitor element group
	CreateElementGroup(Partition, IElementPartitionMapper)	Create a clone of the progenitor element group
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetObjectData	Populate the serialization info with the data necessary to serialize this object.
	GetProtoElement	Get the ProtoElement corresponding to the specified id.
	GetProtoLink	Get the ProtoLink corresponding to the specified id.
	GetProtoLinks	Returns an IList of ProtoLink objects that contain the passed ProtoElementBase playing in the passed DomainRoleId.
	GetReconstitutedElement	Returns the reconstituted ModelElement given the guid of the source ModelElement.
	GetSourceRootElementId	Gets the id of the source root ModelElement that corresponds to the specified target root ModelElement id. If it was not found, Guid.Empty is returned.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsInRole	Returns true if the passed ProtoElementBase plays in the passed role in this ElementGroupPrototype.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ResolveProtoLinks	Resolves the passed IList of ProtoLinks into the ProtoElements that play in the passed DomainRoleId.
	ToString()	Returns a string that represents the current object. (Inherited from Object.)
	ToString(Partition)	Dumps out the names of the Elements and ElementLinks in this ElementGroupPrototype, given the DomainClass definitions in the provided partition.

Fields

	Name	Description
	CreatingKey	Key for context info search
	DefaultDataFormatName	The default data format name for the ElementGroupPrototype.
	ElementGroupIdDictionary	Key used in the TargetContext ElementGroupContext for the Element Id dictionary and root element (Id) lists.
	RootElementIdList	Key used in the Source and Target Context ElementGroupContext for the RootElement Id list and root element (Id) lists.
	RootElementList	Key used in the Source and Target Context ElementGroupContext for the RootElement list and root element lists.

Remarks

An ElementGroupPrototype (EGP) contains a pattern of elements and links, which can be used to create a new set of elements and links in a merge operation. During the merge, the EGP is used to create an ElementGroup, which is then linked into the elements in the target model.

EGPs are used for the following purposes:

• To carry information in a drag operation;

• To store information on the clipboard;

• To store a pattern of objects in a toolbox.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
