Subject [jira] [Updated] (LUCENE-7936) Extend Geoshape interfaces so objects can be copied/serialized
Date Tue, 29 Aug 2017 15:02:00 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-7936?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ignacio Vera updated LUCENE-7936:
---------------------------------
    Attachment: LUCENE-7936-code.patch

Attached the patch. I could not run precommit locally because some errors in some other classes
but I want to check if the apporoach I am taking is OK with you.

I cannot add the lookup table for supported classes in the interface so I created a protected
class to contain it. I am actually using a List to hold the classes. Is that ok with you?

Thanks!

> Hi [~david.wright@bksv.com],
> I would like to propose to extends the GeoShape interfaces to be able to copy/serialized
the objects. The current status and  propose change is as following:
> GeoPoint: It can be serialized by using x, y, z
> GeoCircle:  It can be serialized by using getCenter() and getRadius() and getPlanetModel()
> GeoCompositeShape: It can be serialized by accesing shapes using size() and GetShape(int
index)
> GeoPath: add methods to the interface getPoints() and getCutoffAngle()
> GeoPolygon: This is the most complicated one as we have different types:
>    1.- GeoCompositePolygon is just a composite
>    2.- GeoConcavePolygon and GeoConvexPolygon: Create a new interface for those polygons
which exposes the points, holes, internaledges and concavity/convexity
>    3.- GeoComplexPolygons: Do nothing, they are too complex to be serialize??
> I am intersested in accesing the discreatization of the polygons into convex and concave
ones for other reasons as well. I think this should be expose as they end result can be used
for other use cases.
> Cheers,
> I.
