[udig-devel] fileFormat extension point

[Jody Garnett <jody.garnett@xxxxxxxxx>]

Today I am kicking the tires of the fileFormat extension point -- which is used like so:

    <extension

          id="net.refractions.udig.catalog.shp.fileFormat"

          point="net.refractions.udig.catalog.ui.fileFormat">

       <fileService

             fileExtension="*.shp"

             name="%fileService.name"/>

    </extension>

Mostly I am filling in the description information so it is easier to fill in for 1st time users (cause I never remember that * is needed).

I am also looking at this with an eye for the generic datastore supported; I need to programatically come up with a list of supported file extensions - and doing the same thing for the imageio-ext formats would also be smart.

So I am thinking of allowing ...

    <extension

          id="net.refractions.udig.catalog.shp.fileFormat"

          point="net.refractions.udig.catalog.ui.fileFormat">

       <fileService

             fileExtension="*.shp"

             name="%fileService.name"/> <!-- explicit is still allowed -->

       <dynamic

             provider="net.refractions.udig.catalog.geotools.data.DataStoreFormatProvider" />

    </extension>

 

The "FormatProvider" interface would need to produce a Map<String,String> documenting extension and format name.
