The Abiword implements the Model-View-Controller paradigm. The PieceTable is the model of the AbiWord document. It describes exactly how the document is constructed.

Plans

Possible plans post 2.8 for the PieceTable:

• remove switch to use std:: containers
• make it type safe by eliminating PL_StruxDocHandle and replacing it with pf_Strux.
