public class TLcdSurface extends ALcdShape implements ILcdEditableSurface, ILcdCache
ILcdEditableSurface.
This class is thread-safe for concurrent read-only access of its contents. For read-write access, external locking must be used. Such locking is typically done at the model level.

TLcdSurface() |
| Modifier and Type | Method and Description |
|---|---|
void |
clearCache()
Clears the cache.
|
Object |
clone()
Creates and returns a copy of this object, by delegating to
Object.clone(). |
boolean |
contains2D(double aX,
double aY)
Checks whether this
ILcdShape contains the given point in
the 2D space. |
boolean |
contains3D(double aX,
double aY,
double aZ)
Checks whether this
ILcdShape contains the given point in
the 3D space. |
boolean |
equals(Object aObject)
An object is considered equal to this shape if it has the same class.
|
ILcdBounds |
getBounds()
Returns the
ILcdBounds by which the geometry of this ILcdBounded object
is bounded. |
Object |
getCachedObject(Object aKey)
Looks up and returns the cached Object corresponding to the given key.
|
ILcdRing |
getExteriorRing()
Returns the exterior boundary of this surface.
|
ILcdPoint |
getFocusPoint()
Returns the focus point of this
ILcdShape. |
List<ILcdRing> |
getInteriorRings()
Returns the holes in this surface, as a list of
ILcdRing instances. |
int |
hashCode()
The hash code of this shape is the hash code of its class, in order to
be consistent with the
ALcdShape.equals(Object) method. |
void |
insertIntoCache(Object aKey,
Object aObject)
Inserts a cache Object corresponding to the given key Object.
|
Object |
removeCachedObject(Object aKey)
Looks up and removes the cached Object corresponding to the given key.
|
void |
setExteriorRing(ILcdRing aRing)
Sets the exterior boundary of this surface.

ILcdBoundedILcdBounds by which the geometry of this ILcdBounded object
is bounded.
If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points)
the return value is unspecified.
It is highly recommended to return an undefined bounds.
You can create undefined bounds using the default constructors
of TLcdLonLatBounds
or TLcdXYBounds.

Note that this implementations may throw a
ClassCastException or IllegalArgumentException
in case the class of the ring is not
compatible with the implementation of the surface. Implementations should
specify in their documentation all restrictions that apply in this context.

If there are no holes, an empty list is returned.
The returned list is editable and can be used to add, remove or replace interior rings.

ALcdShapeObject.clone(). Extensions should delegate to this implementation
with super.clone(), in order to create an object instance of
the right type, with all fields copied. They then should explicitly
clone any non-primitive fields for which a deeper clone is required.clone in interface ILcdCloneableclone in class ALcdShapeObject.clone()public boolean equals(Object aObject)

The key must therefore be a unique identifier, typically the caller
