This folder contains the stores and utilities implementing the proposed new Dojo Object Store API,
|
||||
a successor and unifier to Dojo Data, Dojo Storage, and potentially Dojo Model. These
|
||||
stores are brand new, and designed to provide simple lightweight implementations
|
||||
providing core functionality for typical applications. These modules are under active
|
||||
development, and exist here at this time to provide maximum visibility to the
|
||||
efforts to design and develop this new API and set of base stores. The goal is
|
||||
to have these stores ready for Dojo 1.6. In the meantime, these stores are likely to
|
||||
have API changes, may be missing some functionality, tests, and/or documentation.
|
||||
If these modules are not deemed suitably stable by the 1.6 release, this directory (or
|
||||
individual modules) will be removed and be given a later release target.
