In this video, explore how to add navigation properties to collection pages to improve discoverability in the API.
- [Instructor] If we want our paged collection responses…to truly satisfy the HATEOAS constraint,…they should include navigation properties…that allow the client to move through the pages…by following links on the pages.…The PagedCollection class already includes…these navigation properties.…The next step is to write some code…that will automatically populate these links.…I'll make a new static method at the top of this class…called, public static PagedCollection of T, Create,…and this'll take a self link,…an array of items,…an int size for the total size of the collection,…and an instance of PagingOptions.…
And all this method is gonna do…is create a new PagedCollection of T,…and copy over these items, to say Self equals self,…Value equals items, Size equals size,…Offset comes from the pagingOptions dot Offset,…Limit comes from the pagingOptions dot Limit,…the First link is just self,…and then for the next, previous, and last links,…we need to write some new methods.…
We'll say Next equals GetNextLink,…given self, size, and pagingOptions.…
