Nicholas Paldino updated LUCENENET-292:
---------------------------------------
Attachment: SupportClass.patch
- Made class public in case it is needed for testing purposes (along with
AddRange method)
- Retained comments on constructors. Since it is in SupportClass, and not a
class that is ported over, having comments on this class does not hinder
advancing the project at this point. There is no need to remove them.
Current SupportClass.patch has these changes and all others mentioned.
> Optimization of EquatableList<T>
> --------------------------------
>
> Key: LUCENENET-292
> URL: https://issues.apache.org/jira/browse/LUCENENET-292
> Project: Lucene.Net
> Issue Type: Improvement
> Reporter: Nicholas Paldino
> Priority: Minor
> Attachments: EquatableList3.patch, SupportClass.patch
>
>
> When comparing two IEnumerable<T> implementations, a shortcut can be taken to
> check to see if both IEnumerable<T> expose operations which returns a count
> of items (sequences cannot be equal if the number of elements in the
> sequences are not equal).
> Typically, in .NET, this is expressed through the implementation of the
> ICollection or ICollection<T> interface.
> Before enumerating through each element and comparing the two for equality,
> if the counts are accessible, they should be compared to see if the number of
> elements in the two sequences are equal. If a comparison is able to be made
> before enumerating, it will be much more performant for comparisons of
> sequences where each is ~N, but both are not equal to N, and N is very large.
> Patch to follow.
