###
Companion object TreeUnpickler

#### class TreeUnpickler[Tasty <: TastyUniverse] extends AnyRef

`TreeUnpickler` is responsible for traversing all trees in the "ASTs" section of a TASTy file, which represent the definitions inside the classfile associated with the root class/module. `TreeUnpickler` will enter the public api of the TASTy file into the symbolTable of `TastyUniverse`. "Public API" includes annotations when they are simple trees.

Where possible, `TreeUnpickler` should not directly manipulate values created by the symbolTable, but use operations provided by `TastyUniverse`

### Instance Constructors

1.  new TreeUnpickler(reader: TastyReader, nameAtRef: (NameRef) => TastyName)(implicit tasty: Tasty)

   reader

     the reader from which to unpickle

   nameAtRef

     an index of names from the tasty file of this unpickler

   tasty

     the handle on the `TastyUniverse`

### Type Members

1.  class Completer extends Tasty.TastyCompleter

   A completer that captures the current position and context, which then uses the position to discover the symbol to compute the info for.

2.  class OwnerTree extends AnyRef

   A lazy datastructure that records how definitions are nested in TASTY data.

   A lazy datastructure that records how definitions are nested in TASTY data. The structure is lazy because it needs to be computed only for forward references to symbols that happen before the referenced symbol is created (see `symbolAt`). Such forward references are rare.

3.  class TreeReader extends AnyRef

### Deprecated Value Members

1.  def formatted(fmtstr: String): String

     StringFormat
   Annotations
     @deprecated @inline()
   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.

2.  def →[B](y: B): (TreeUnpickler[Tasty], B)

     (Since version 2.13.0) Use `->` instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
