Description
TDelegatedEqualityComparer delegates all calls to user-provided callback routines.
The primary role of TDelegatedEqualityComparer is to delegate all calls made to its GetHashCode and Equals methods to the user-supplied routines.
Use TDelegatedEqualityComparer when creating a descendant class from TEqualityComparer is not an option. Another useful feature of TDelegatedEqualityComparer is the fact that anonymous methods can be used in Delphi language to provide the required callbacks inline.
