public class CircleFunction extends GeometryFunction
It represents the CIRCLE function of the ADQL language.
This function expresses a circular region on the sky (a cone in space) and corresponds semantically to the STC circle region. The function arguments specify the coordinate system, the center position, and the radius (in degrees).
Example:
CIRCLE('ICRS GEOCENTER', 25.4, -20.0, 1)
In this example the function expresses a circle of one degree radius centered in a position of (25.4, -20.0) degrees and defined according to the ICRS coordinate system with GEOCENTER reference position.- Version:
