java - ESRI Geometry API - how to choose QuadTree query tolerance -

-

i'm playing around esri geometry api. documentation getiterator methods doesn't explain tolerance parameter does. code doesn't shed light on kind of values appropriate. unit tests use 0.0, except single test uses 0.001.

what factors should consider when choosing value tolerance? put way, if best value typically 0.0, when else?

generally 1mm. example if coordinates wgs84, can use 1e-8 degrees.
