| Modifier and Type | Method and Description | 
|---|---|
static IServiceProvider | 
AccessConstraintHelper.getConstrainedLinkEnd(ILinkConstraint constraint)
Gets the object at the end of the link to which a specified constraint is applied. 
 | 
static VectorDisplacement | 
AccessConstraintHelper.getDisplacementVectorForLinkConstraint(ILinkConstraint constraint)
Gets the displacement vector for a given link constraint and time observer. 
 | 
static Evaluator<JulianDate> | 
AccessConstraintSampling.getNextStepFromRelativeMotionEvaluator(ILinkConstraint constraint,
                                      double maximumAngularMotion,
                                      EvaluatorGroup group)
Gets an evaluator that determines the next time at which to sample a constraint function
    based on the relative motion between two objects and a maximum relative motion per step.

class  | 
AngleInPlaneConstraint
An access constraint that projects the displacement vector from one object to another into a given axis-aligned plane
 and requires that the angle of the projected vector, measured from the first axis defining the plane toward the second,
 is within a range of values. 
 | 
class  | 
AngleOutOfPlaneConstraint
An access constraint that requires that the angle of the displacement vector between two objects above a given
 axis-aligned plane is within a range of values. 
 | 
class  | 
AzimuthAngleConstraint
 | 
class  | 
AzimuthAngleRateConstraint
 | 
class  | 
AzimuthElevationMaskConstraint
An Access constraint that determines whether the object at the other end of the  
ConstrainedLink (get / set)
 is visible based on an AzimuthElevationMask associated with the ConstrainedLinkEnd (get / set). | 
class  | 
CentralBodyObstructionConstraint
An Access constraint that requires that the view from one object to another not be obstructed by
 a central body such as the Earth or another planet. 
 | 
class  | 
CentralBodySurfaceCurveElevationAngleConstraint
An Access constraint that requires that an object be between a span of elevation angles
 from any or all of the points along a given line on the surface of the central body. 
 | 
class  | 
CentralBodySurfaceRegionElevationAngleConstraint
An  
AccessConstraint that requires that an object be between a span of elevation angles
 from any or all of the points in a given area on the surface of the CentralBody (get / set). | 
class  | 
CentralBodySurfaceRegionSensorVolumeConstraint
An access constraint that requires that an  
EllipsoidSurfaceRegion attached to one end of the
 ConstrainedLink (get / set) be partially within the volume of the sensor attached to the other end of the link. | 
class  | 
CircularEquatorialOrbitGrazingAngleConstraint
 | 
class  | 
CommunicationLinkConstraint

CommunicationLinkScalar. |
