public abstract class ALcdShape extends Object implements ILcdShape
This abstract class provides a basis for implementing the ILcdShape interface.
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.
Warning: when using extensions of this class directly as domain objects (=model elements),
make sure to override the equals(Object) and hashCode() methods so that two different domain objects
with the same geometry are not considered equal.
See the equals() and hashCode() requirements for domain objects article for more information.

Object |
clone()
Creates and returns a copy of this object, by delegating to
Object.clone(). |
boolean |
contains2D(ILcdPoint aPoint)
Checks whether this
ALcdShape contains the given point in the
2D cartesian plane. |
boolean |
contains3D(ILcdPoint aPoint)
Checks whether this
ALcdShape 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.
|
static ILcdShape |
fromDomainObject(Object aObject)
Returns a shape for the given object.
|
int |
hashCode()
The hash code of this shape is the hash code of its class, in order to
be consistent with the
equals(Object) method. |

Returns a shape for the given object. The given object is usually a domain object, i.e. an object retrieved from the model. It returns a shape in the following cases:
Object is an ILcdShape.Object is an ILcdDataObject whose type contains a TLcdHasGeometryAnnotation with an ILcdShape property.In other cases, this method returns null.
One should never check if an Object is a shape using instanceof, but use this method
instead and perform a null-check on the result.

Object.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 ObjectObject.clone()public boolean equals(Object aObject)

Extensions should refine this implementation, based on their properties.
