# Interface Position

public interface Position
Represents a location within a document. It is intended to abstract away implementation details of the document and enable specification of positions within the document that are capable of tracking of change as the document is edited.

A `Position` object points at a location between two characters. As the surrounding content is altered, the `Position` object adjusts its offset automatically to reflect the changes. If content is inserted or removed before the `Position` object's location, then the `Position` increments or decrements its offset, respectively, so as to point to the same location. If a portion of the document is removed that contains a `Position`'s offset, then the `Position`'s offset becomes that of the beginning of the removed region. For example, if a `Position` has an offset of 5 and the region 2-10 is removed, then the `Position`'s offset becomes 2.

`Position` with an offset of 0 is a special case. It never changes its offset while document content is altered.
