Hi,
Is there a way to implement the "CreateNode" method in my
library abstract below? Or can this only be done in client code outside the library? I current get the error "Cannot create an instance of the abstract class or interface 'ToplogyLibrary.AbstractNode"
public abstract class AbstractTopology<T>
{
// Properties
public Dictionary<T, AbstractNode<T>> Nodes { get; private set; }
public List<AbstractRelationship<T>> Relationships { get; private set; }
// Constructors
protected AbstractTopology()
{
Nodes = new Dictionary<T, AbstractNode<T>>();
}
// Methods
public AbstractNode<T> CreateNode()
{
var node = new AbstractNode<T>(); // ** Does not work **
Nodes.Add(node.Key, node);
}
}
}
public abstract class AbstractNode<T>
{
public T Key { get; set; }
}
public abstract class AbstractRelationship<T>
{
public AbstractNode<T> Parent { get; set; }
public AbstractNode<T> Child { get; set; }
}
