net.algart.math.patterns.TooManyPointsInPatternError

Error thrown if a {@link Pattern pattern} is extremely large to be correctly processed."Extremely large" usually means that the number of points of the pattern is greater, or is probably greater, than Integer.MAX_VALUE=2³¹−1, but the method cannot process such number of points due to Java limits, connected with 32-bit indexing. The typical example is {@link Pattern#points()} method,which throws this exception if the number of points is greater than Integer.MAX_VALUE: this method returns result as Java Set type, which is limited by 2³¹−1 elements.

Usually OutOfMemoryError is also probable in situations, when this exception is probable.

                // we build a Java array of all pattern points, so it is impossible to process more
                // than Integer.MAX_VALUE points.
                // In this branch, it is theoretically possible to process up to Long.MAX_VALUE points,
