Subject [jira] [Created] (SIS-186) Set Shapefile as a subclass of DataStore
Date Thu, 18 Dec 2014 04:09:14 GMT
Martin Desruisseaux created SIS-186:
---------------------------------------

             Summary: Set Shapefile as a subclass of DataStore
                 Key: SIS-186
                 URL: https://issues.apache.org/jira/browse/SIS-186
             Project: Spatial Information Systems
          Issue Type: Sub-task
          Components: Shapefile
            Reporter: Martin Desruisseaux


{{Shapefile}} currently extends {{Object}}. It should extends {{org.apache.sis.storage.DataStore}},
since the later is targeted as the base class of all data readers (currently NetCDF and ISO
19139 metadata).

The intend of having a base class for all data readers is to allow applications to process
data without knowledge about whether the data are stored in a Shapefile or a NetCDF file.
The SIS command-line tools is an example of such application.

In the current state of {{DataStore}} class, the main implication is that {{Shapefile}} must
implement the {{getMetadata()}} and {{close()}} methods. A proposed implementation is attached
to this task. Future {{DataStore}} versions will require more methods, but their API is not
yet designed.

Of course, if the {{DataStore}} API is considered problematic for {{Shapefile}}, we can revisit
it according feedbacks.
