[ASTERIXDB-2711] st_n_rings() function in geometry module

Description

st_n_rings() function returns the number of rings of polygons and multipolygons. When I insert a multipolygon into the dataset and use the function, there is an exception, saying "geometryN: n out of range [IllegalArgumentException]".

 

The Exception is thrown by Esri API. What we need to modify is at line 49, Class STNRingsDescriptor. I think we need to modify the scale of for loop to from 0 to numGeometries rather than from 1 to numGeometries + 1.

 

Thanks.
