Package apollo.dataadapter.das Description

Defines the interfaces to support the reading of DAS datasources by Apollo. The goal is allow different implementations to be provided of, for example, DASServer. These implementations can be sophisticated or not, as necessary.

I have included a reference (very direct, unsophisticated) implementation in the apollo.dataadapter.das.simple package.

The interface DASServer is the basic type referred to by a data adapter referencing a DAS datasource. The DASDsn, DASSegment, DASFeature and DASSequence are types used to pass information into a request from the server, and to retrieve information back from the server.
