Build a region using the instance as a prototype.

protected void 
computeGeometricalProperties()
Compute some geometrical properties.

The leaf nodes of the BSP tree must have a
Boolean
attribute representing the inside status of
the corresponding cell (true for inside cells, false for outside
cells). In order to avoid building too many small objects, it is
recommended to use the predefined constants
Boolean.TRUE
and Boolean.FALSE
tree

 tolerance below which points are considered identical.public IntervalsSet(Collection<SubHyperplane<Euclidean1D>> boundary, double tolerance)
The boundary is provided as a collection of subhyperplanes
. Each subhyperplane has the
interior part of the region on its minus side and the exterior on
its plus side.
The boundary elements can be in any order, and can form
several nonconnected sets (like for example polygons with holes
or a set of disjoints polyhedrons considered as a whole). In
fact, the elements do not even need to be connected together
(their topological connections are not used here). However, if the
boundary does not really separate an inside open from an outside
open (open having here its topological meaning), then subsequent
calls to the checkPoint
method will not be meaningful anymore.
If the boundary is empty, the region will represent the whole space.

This method allow to create new instances without knowing exactly the type of the region. It is an application of the prototype design pattern.
The leaf nodes of the BSP tree must have a
Boolean
attribute representing the inside status of
the corresponding cell (true for inside cells, false for outside
cells). In order to avoid building too many small objects, it is
recommended to use the predefined constants
Boolean.TRUE
and Boolean.FALSE
. The
tree also must have either null internal nodes or
internal nodes representing the boundary as specified in the
getTree
method).

This method builds this intervals set as an ordered list of
Interval
elements. If the intervals set has no
lower limit, the first interval will have its low bound equal to
Double.NEGATIVE_INFINITY
. If the intervals set has
no upper limit, the last interval will have its upper bound equal
to Double.POSITIVE_INFINITY
. An empty tree will
build an empty list while a tree representing the whole real line
will build a one element list with both bounds being
infinite.
