Method Detail

assertIntersects

public static void assertIntersects(Envelope env1,
                    Envelope env2)

Asserts that the given envelopes intersect. The coordinate reference systems used by the envelopes do not have to be the same; a coordinate transformation will be attempted if necessary. More specifically, this method asserts that the envelopes are not disjoint.

 a.Intersects(b) <--> ! a.Disjoint(b)
 
 

Parameters:

env1 - An Envelope representing a spatial extent.

env2 - An Envelope object representing some other spatial extent.
