Package apollo.dataadapter.das.simple

Defines the interfaces to support the reading of DAS datasources by Apollo.

          Description

Class Summary
DASDsnContentHandler I am the ContentHandler used when SimpleDASServer parses the result of a 'dsn' call to a das data source.
DASEntryPointContentHandler I am the ContentHandler used when SimpleDASServer parses the result of a 'entry_points' call to a das data source and dsn.
DASFeatureContentHandler I am the ContentHandler used when SimpleDASServer parses the result of a 'features' call to a das data source (with a specified dsn and segment).
DASSequenceContentHandler I am the ContentHandler used when SimpleDASServer parses the result of a 'dna' call to a das data source (passing in dsn and segment).
SimpleDASAdapter I implement a AbstractDataAdapter, allowing Apollo to get information from DAS datasources, using 'simple' implementions of DASServerI, DASDsn etc.
SimpleDASAdapterGUI I implement a AbstractDataAdapterUI, allowing Apollo to get information from DAS datasources, using 'simple' implementions of DASServerI, DASDsn etc.
SimpleDASDsn  
SimpleDASFeature I am a lightweight implementation of the DASFeature interface.
SimpleDASSegment I am a lightweight implementation of the DASSegment interface.
SimpleDASSequence I am a lightweight implementation of the DASSequence interface.
SimpleDASServer I am a lightweight implementation of a DAS Server which doesn't use external code (apart from a general SAX-parser).
 

Package apollo.dataadapter.das.simple 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.
