* [License] Simplify the Texture license to be pure Apache 2 (removing ASDK-Licenses)
With permission of the Facebook Open Source team, we are simplifying the Texture
license so that clients can rely on the Apache 2 terms that most of Texture is
already covered by. This means that code originally forked from AsyncDisplayKit
will be re-licensed from "BSD 3-clause + PATENTS v2" to Apache 2 without a
PATENTS file.
After getting confirmation that the updates to these core files look good, we'll
propagate this new license header to all files (in this same PR) and get sign-off
from all parties before landing.
* [License] Update all Texture source files to be pure Apache 2.
* Changelog entry for Apache 2 license update.
* Revert "[License] Update all Texture source files to be pure Apache 2."
This reverts commit ffa0fbbba9717d871dd16c4b07539f2f8208fc2b.
* [License] Update all Texture source files to be pure Apache 2, maintaining copyrights.
* [License] Update CONTRIBUTING, README, Podspec & Dangerfile.
* [ASCollectionView] Fix index space translation of Flow Layout Delegate methods.
This includes a few other cleanups, including overflow of signed integer indices.
* [ASCollectionView] Improve code sharing of UIKit size method calls; ensure delegate invalidation re-fetches supplementary sizes too.
* [ASCollectionView] Final method ordering and doc-comment for new _sizeForUIKitCellWithKind:atIndexPath: method.
* Introduce ASCollectionViewLayout
- `ASCollectionViewLayout` is an async `UICollectionViewLayout` that encapsulates its layout calculation logic into a separate thread-safe object which can be used ahead of time and/or on multiple threads.
- `ASDataController` now can prepare for a new layout resulted from a change set before `ASCollectionView` even knows about it. By the time the change set it ready to be consumed by `ASCollectionView`, its new layout is also ready.
- New `ASCollectionViewLayoutCalculating` protocol that is simple and generic enough that many types of calculators can be built on top. `ASCollectionViewLayoutSpecCalculator` conforms to `ASCollectionViewLayoutCalculating` protocol and can be backed by any layout spec (e.g `ASStackLayoutSpec`, `PIMasonryLayoutSpec`, etc). We can even build a `ASCollectionViewLayoutYogaCalculator` that uses Yoga internally.
- A built-in `ASCollectionViewFlowLayoutCalculator` that is a subclass of `ASCollectionViewLayoutSpecCalculator` and uses a multi-threaded multi-line `ASStackLayoutSpec` internally. The result is a performant and thread-safe flow layout calculator.
- Finally, `ASCollectionViewLayout` can be subclassed to handle a specific type of calculator with optimizations implemented based on the knowledge of such calculator. For example, `ASCollectionViewFlowLayout` can have a highly optimized implementation of `-layoutAttributesForElementsInRect:`.
Protocolize layout calculator providing and consuming
Add flex wrap documentation
Add a `multithreaded` flag to ASStackLayoutSpec that forces it to dispatch even if it's off main
- Update ASCollectionViewFlowLayoutSpecCalculator to use that flag.
Minor change in ASCollectionViewLayout
Implement Mosaic layout calculator
Minor change
Fix project file
Rename and fix project file
Skip fetching constrained size only if a layout calculator is available
Update examples/ASCollectionView
Remove unnecessary change in ASTableView
Address comments
Rename collection view calculator protocols
Minor changes after rebasing with master
Add ASLegacyCollectionLayoutCalculator for backward compatibility
Remove ASCollectionLayoutSpecCalculator
Remove ASLegacyCollectionLayoutCalculator
Introduce ASCollectionLayout
- A wrapper object that contains content size and an element to rect table.
- Collection layout calculators to return this new object instead of an ASLayout.
Before adding a content cache
Finishing hooking up ASCollectionLayoutDataSource to ASCollectionNode
Stash
Finish ASCollectionLayout
Rough impl of ASCollectionFlowLayout
Revert changes in CustomCollectionView example
Move ASRectTable back to Private
* Rename ASCollectionContentAttributes to ASCollectionLayoutState
* Address other comments
* Introduce ASCollectionLayoutDelegate and make ASCollectionLayout private
* Address comments
* API tweaks:
- Replace `-layoutContextWithElementMap:` in ASCollectionLayoutDelegate with `-additionalInfoForLayoutWithElements:`. The returned object is then stored in ASCollectionLayoutContext for later lookups.
- ASCollectionLayoutContext has no public initializer.
- ASDataControllerLayoutDelegate no longer requires a context of type ASCollectionLayoutContext but simply an `id`. This helps decouple ASDataController and ASCollectionLayout.
- Rename `elementMap` to `elements`.
- Rename `visibleMap` to `visibleElements`.
- Other minor changes.
* Rename ASCGSizeHash to ASHashFromCGSize
* Make sure to call super in -[ASCollectionLayout prepareLayout]
* Update example/ASCollectionView to use ASCollectionFlowLayoutDelegate
* Remove unnecessary change
