adoptChild method

void adoptChild(
  1. RestorationBucket child
)

Adopts the provided child bucket.

The child will be dropped from its old parent, if it had one.

The child is stored under its restorationId in this bucket. If this bucket already contains a child bucket under the same id, the owner of that existing bucket must give it up (e.g. by moving the child bucket to a different parent or by disposing it) before the end of the current frame. Otherwise an exception indicating the illegal use of duplicated restoration IDs will trigger in debug mode.

No-op if the provided bucket is already a child of this bucket.

Implementation

void adoptChild(RestorationBucket child) {
  assert(_debugAssertNotDisposed());
  if (child._parent != this) {
    child._parent?._removeChildData(child);
    child._parent = this;
    _addChildData(child);
    if (child._manager != _manager) {
      _recursivelyUpdateManager(child);
    }
  }
  assert(child._parent == this);
  assert(child._manager == _manager);
}
