public RatIntGeomTests2D()

Method Detail

aboveBelow

public int aboveBelow(Point2D q,
                      Point2D p)

Specified by:

aboveBelow in interface TwoArgsGeomTests2D

Following copied from interface: jdsl.geomobj.api.TwoArgsGeomTests2D

Parameters:

q - a point

p - a point

Returns:

whether q is GeomTester2D.ABOVE, GeomTester2D.Y_ALIGNED, or GeomTester2D.BELOW p

Throws:

InvalidPointException - if either p or q is Point2D.INFINITE

leftRight

public int leftRight(Point2D q,
                     Point2D p)

Specified by:

leftRight in interface TwoArgsGeomTests2D

Following copied from interface: jdsl.geomobj.api.TwoArgsGeomTests2D

Parameters:

q - a point

p - a point

Returns:

whether q is to the GeomTester2D.LEFT, GeomTester2D.X_ALIGNED, or to the GeomTester2D.RIGHT of p

Throws:

InvalidPointException - if either p or q is Point2D.INFINITE

compareSlopes

public int compareSlopes(LinearCurve2D lc1,
                         LinearCurve2D lc2)

Specified by:

compareSlopes in interface TwoArgsGeomTests2D

Following copied from interface: jdsl.geomobj.api.TwoArgsGeomTests2D

Parameters:

lc1 - a linear curve

lc2 - a linear curve

Returns:

whether lc1 has a GeomTester2D.LESSER, GeomTester2D.EQUAL, or GeomTester2D.GREATER slope than lc2

insideOutside

public int insideOutside(Point2D q,
                         Circle2D c)

Specified by:

insideOutside in interface TwoArgsGeomTests2D

Following copied from interface: jdsl.geomobj.api.TwoArgsGeomTests2D

Parameters:

q - a point

c - a circle

Returns:

whether q is GeomTester2D.INSIDE, GeomTester2D.ON, or GeomTester2D.OUTSIDE c

Throws:

InvalidPointException - if q is Point2D.INFINITE
