AssetTree

Package: com.hypixel.hytale.builtin.asseteditor

public class AssetTree

Represents the sorted file tree for a single asset pack. Maintains two separate lists of AssetEditorFileEntry objects for Server/ and Common/ directories, protected by a StampedLock for concurrent read/write access. Supports file lookup via binary search, insertion with parent directory creation, removal with subtree cleanup, and batch application of asset changes.

Constructor

public AssetTree(Path rootPath, String packKey, boolean isReadOnly, boolean canBeDeleted)

public AssetTree(Path rootPath, String packKey, boolean isReadOnly, boolean canBeDeleted, Collection<AssetTypeHandler> assetTypes)

The second constructor immediately loads the file tree by walking Server/ (filtered by registered asset type paths) and Common/ directories.
