lower - lower bound of the interval, must be lesser or equal
to upper (may be Double.NEGATIVE_INFINITY)upper - upper bound of the interval, must be greater or equal
to lower (may be Double.POSITIVE_INFINITY)public IntervalsSet(BSPTree<Euclidean1D> tree)
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 - inside/outside BSP tree representing the intervals setpublic IntervalsSet(Collection<SubHyperplane<Euclidean1D>> boundary)
The boundary is provided as a collection of sub-hyperplanes. Each sub-hyperplane 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 non-connected 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 Region.checkPoint() method will not be meaningful anymore.
If the boundary is empty, the region will represent the whole space.
boundary - collection of boundary elementspublic IntervalsSet buildNew(BSPTree<Euclidean1D> tree)
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).

The properties to compute are the barycenter and the size.

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 beeing infinite.
