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.
