Method Detail

write
public void write(OutputStream outputStream) throws IOException
Description copied from interface:SerializableObject
Serialize to output stream.- Specified by:
write
in interfaceSerializableObject
- Overrides:
write
in classBasePlanetObject
- Parameters:
outputStream
- is the output stream to write to.- Throws:
IOException
-
expand
public GeoBBox expand(double angle)
Description copied from interface:GeoBBox
Expand box by specified angle.- Parameters:
angle
- is the angle amount to expand the GeoBBox by.- Returns:
- a new GeoBBox.
-
isWithin
public boolean isWithin(double x, double y, double z)
Description copied from interface:Membership
Check if a point is within this shape.- Parameters:
x
- is x coordinate of point to check.y
- is y coordinate of point to check.z
- is z coordinate of point to check.- Returns:
- true if the point is within this shape
-
getRadius
public double getRadius()
Description copied from interface:GeoSizeable
Returns the radius of a circle into which the GeoSizeable area can be inscribed.- Returns:
- the radius.
-
getCenter
public GeoPoint getCenter()
Description copied from interface:GeoSizeable
Returns the center of a circle into which the area will be inscribed.- Returns:
- the center.
-
getEdgePoints
public GeoPoint[] getEdgePoints()
Description copied from interface:GeoShape
Return a sample point that is on the outside edge/boundary of the shape.- Returns:
- samples of all edge points from distinct edge sections. Typically one point is returned, but zero or two are also possible.
-
intersects
public boolean intersects(Plane p, GeoPoint[] notablePoints, Membership... bounds)
Description copied from interface:GeoShape
Assess whether a plane, within the provided bounds, intersects with the shape's edges. Any overlap, even a single point, is considered to be an intersection. Note well that this method is allowed to return "true" if there are internal edges of a composite shape which intersect the plane. Doing this can cause getRelationship() for most GeoBBox shapes to return OVERLAPS rather than the more correct CONTAINS, but that cannot be helped for some complex shapes that are built out of overlapping parts.- Parameters:
p
- is the plane to assess for intersection with the shape's edges or bounding curves.notablePoints
- represents the intersections of the plane with the supplied bounds. These are used to disambiguate when two planes are identical and it needs to be determined whether any points exist that fulfill all the bounds.bounds
- are a set of bounds that define an area that an intersection must be within in order to qualify (provided by a GeoArea).- Returns:
- true if there's such an intersection, false if not.
-
intersects
public boolean intersects(GeoShape geoShape)
Description copied from interface:GeoAreaShape
Assess whether a shape intersects with any of the edges of this shape. Note well that this method must return false if the shape contains or is disjoint with the given shape. It is permissible to return true if the shape is within the specified shape, if it is difficult to compute intersection with edges.- Parameters:
geoShape
- is the shape to assess for intersection with this shape's edges.- Returns:
- true if there's such an intersection, false if not.
-
getBounds
public void getBounds(Bounds bounds)
Description copied from interface:Bounded
Compute bounds for the shape.- Specified by:
getBounds
in interfaceBounded
- Overrides:
getBounds
in classGeoBaseBounds
- Parameters:
bounds
- is the input bounds object. The input object will be modified.
-
getRelationship
public int getRelationship(GeoShape path)
Description copied from interface:GeoArea
Find the spatial relationship between a shape and the current geo area. Note: return value is how the GeoShape relates to the GeoArea, not the other way around. For example, if this GeoArea is entirely within the shape, then CONTAINS should be returned. If the shape is entirely enclosed by this GeoArea, then WITHIN should be returned.It is permissible to return OVERLAPS instead of WITHIN if the shape intersects with the area at even a single point. So, a circle inscribed in a rectangle could return either OVERLAPS or WITHIN, depending on implementation. It is not permissible to return CONTAINS or DISJOINT in this circumstance, however.
Similarly, it is permissible to return OVERLAPS instead of CONTAINS under conditions where the shape consists of multiple independent overlapping subshapes, and the area overlaps one of the subshapes. It is not permissible to return WITHIN or DISJOINT in this circumstance, however.
- Specified by:
getRelationship
in interfaceGeoArea

path

- the relationship, from the perspective of the shape.
