API of a Jorm mapper used in Speedo.
A Jorm mapper for speedo is a composite component. Here is a picture
representing this composite:
This composite contains 4 components:
- The JormStorageManage component is in charge of managing the
I/O with the data support (read, write) and the identifier management
(export, unexport, bind)
- The JormFactory is in charge of the initialisation of the
persistent classes and the loading of Jorm meta information.
- The Mapper is in charge of referencing persistent classes
initialized and the connection allocation. The connections permit to access
the data support.
- The Pool is used by the Mapper in order to pool physical
connection, when it is not already done by the connection provider.
