Interface IElementComparer

public interface IElementComparer
This interface is used to compare elements in a viewer for equality, and to provide the hash code for an element. This allows the client of the viewer to specify different equality criteria and a different hash code implementation than the equals and hashCode implementations of the elements themselves.
