com.google.collide.shared.document.Document
Document model for the code editor. The document is modeled using a linked list of lines. (This allows for very fast line insertions and still good performance for other common editor operations.) During a text change, listeners will be called in this order:
- {@link Anchor.ShiftListener}
- {@link Anchor.RemoveListener}
- {@link LineCountListener}
- {@link LineListener}
- {@link TextListener}
