IGroupsModel

StockSharp.Xaml.Diagram.GXDiagram.Model

A model that supports a grouping relationship between nodes, with the relationship information stored on each node as collections of related nodes.

Methods

public void AddMemberNodeKey(object nodedata, object membernodekey)

iGroupsModel.AddMemberNodeKey(nodedata, membernodekey)

Add a node data key to the list of "member" node data keys.

public void DoMemberNodeKeyAdded(object nodedata, object memberkey)

iGroupsModel.DoMemberNodeKeyAdded(nodedata, memberkey)

This method should be called when a "member" node data key has been added to the list of members.

public void DoMemberNodeKeyRemoved(object nodedata, object memberkey)

iGroupsModel.DoMemberNodeKeyRemoved(nodedata, memberkey)

This method should be called when a "member" node data key has been removed from the list of members.

public void DoMemberNodeKeysChanged(object nodedata)

iGroupsModel.DoMemberNodeKeysChanged(nodedata)

This method should be called when the list of member key values has been replaced.

public bool GetIsGroupForNode(object nodedata)

result = iGroupsModel.GetIsGroupForNode(nodedata)

This predicate is true when the given node data represents a group of nodes instead of an "atomic" node.

public IEnumerable<object> GetMemberNodesForGroup(object nodedata)

result = iGroupsModel.GetMemberNodesForGroup(nodedata)

Return a collection of member node datas.

IsMember

public bool IsMember(object groupnodedata, object membernodedata)

result = iGroupsModel.IsMember(groupnodedata, membernodedata)

This predicate is true if the is an immediate member of the .

IsMemberValid

public bool IsMemberValid(object groupnodedata, object membernodedata)

result = iGroupsModel.IsMemberValid(groupnodedata, membernodedata)

This predicate is true when it is valid to add the to the .

Returns: false if the cannot be added to

public void RemoveMemberNodeKey(object nodedata, object membernodekey)

iGroupsModel.RemoveMemberNodeKey(nodedata, membernodekey)

Remove a node data key from the list of "member" node data keys.

public void SetMemberNodeKeys(object nodedata, IEnumerable membernodekeys)

iGroupsModel.SetMemberNodeKeys(nodedata, membernodekeys)

Replace the list of "member" node data keys with a new collection of keys.
