      This UICollectionView subclass allows for partial layout invalidation using IGListCollectionViewLayout.

      +
      +

      Note

      + When updating a collection view (ex: calling -insertSections), -invalidateLayoutWithContext gets called on +the layout object. However, the invalidation context doesn’t provide details on which index paths are being modified, +which typically forces a full layout re-calculation. IGListCollectionView gives IGListCollectionViewLayout the +missing information to re-calculate only the modified layout attributes. + +

 The y position of that row is determined by the maximum height (including section insets) of the section/item of the previous row.

    A section with a non-zero height header will always cause that section to newline. Headers are always stretched to the
 width of the collection view, pinched with the section insets.
    
 
 
    Ex. of a section (2,0) with a header inset on the left/right.

    +
    +

    Notify the layout that a specific section was modified before invalidation. Used to optimize layout re-calculation.

    +
    +

    Note

    +

    When updating a collection view (ex: calling -insertSections), -invalidateLayoutWithContext gets called on +the layout object. However, the invalidation context doesn’t provide details on which index paths are being modified, +which typically forces a full layout re-calculation. We can use this method to keep track of which section actually +needs to be updated on the following -invalidateLayoutWithContext. See IGListCollectionView.

      Diffing

      IGListKit uses an algorithm adapted from a paper titled A technique for isolating differences between files by Paul Heckel. This algorithm uses a technique known as the longest common subsequence to find a minimal diff between collections in linear time O(n). It finds all inserts, deletes, updates, and moves between arrays of data.

      +

      The IGListDiffable protocol requires clients to implement two methods, -diffIdentifier and -isEqualToDiffableObject:.

      The method -isEqualToDiffableObject: should perform the same type of check as -isEqual:, but without impacting performance characteristics, like in Objective-C containers such as NSDictionary and NSSet.

      Why are both of these methods required for diffing? The point of having the two methods has to do with identity and equality, where the diff identifier uniquely identifies data (common scenario is primary key in databases). Equality comes into play when comparing the values of two uniquely identical objects (driving reloading).
