@UML(identifier="GM_Primitive", specification=ISO_19107) public interface Primitive extends Geometry
Any geometric object that is used to describe a feature is a collection of geometric primitives.
A collection of geometric primitives may or may not be a geometric complex. Geometric complexes
have additional properties such as closure by boundary operations and mutually exclusive component
parts. Primitive
and Complex
share most semantics, in the meaning of operations
and attributes. There is an exception in that a Primitive
shall not contain its boundary
(except in the trivial case of point where the boundary is empty), while a
complex shall contain its boundary in all cases.

Modifier and Type  Method and Description 

PrimitiveBoundary 
getBoundary()
Returns the boundary of a
Primitive as a set of
Primitive s. 
Set<Complex> 
getComplexes()
Returns the set of complexes which contains this primitive.

Composite 
getComposite()
Returns the owner of this primitive.

Set<Primitive> 
getContainedPrimitives()
Returns the
Primitive s which are by definition coincident with this one. 
Set<Primitive> 
getContainingPrimitives()
Returns the
Primitive s which are by definition coincident with this one. 
OrientablePrimitive[] 
getProxy()
Returns the orientable primitives associated with this primitive.

@UML(identifier="boundary", obligation=MANDATORY, specification=ISO_19107) PrimitiveBoundary getBoundary()
Primitive
as a set of
Primitive
s. This is a specialization of the operation at
Geometry
, which does not restrict the class of the returned collection.
The organization of the boundary set of a Primitive
depends on the
type of the primitive.getBoundary

@UML(identifier="containedPrimitive", obligation=MANDATORY, specification=ISO_19107) Set<Primitive> getContainedPrimitives()
Primitive
s which are by definition coincident with this one.
This allows applications to override the
TransfiniteSet<DirectPosition>
interpretation and its associated computational geometry, and declare one
Primitive
to be "interior to" another.
This set should normally be empty when the Primitive
s are within a
complex, since in that case the boundary
information is sufficient for most cases.
This association should not be used when the two Primitive
s are not close
to one another. The intent is to allow applications to compensate for inherent and
unavoidable round off, truncation, and other mathematical problems indigenous to
computer calculations.getContainingPrimitives()

@Association(value="Oriented") @UML(identifier="proxy", obligation=CONDITIONAL, specification=ISO_19107) OrientablePrimitive[] getProxy()
Primitive
of
dimension 1 or 2 is associated to two orientable primitives,
one for each possible orientation. For curves and surfaces, there are exactly two orientable
primitives for each geometric object. For the positive orientation, the
orientable primitive shall be the corresponding
curve or surface.
This method is mandatory for curves and surfaces
,
and is not allowed for Points and solids. The
later should return null
.
