/** Multiple ranges in one object.
|
|
|
|
This class combines multiple ranges in one object, providing a
|
|
total, enclosing range for it.
|
|
|
|
You can use this class e.g. when updating views containing
|
|
rectangular objects. Add each modified object to a
|
|
B2DMultiRange, then test each viewable object against
|
|
intersection with the multi range.
|
|
|
|
Similar in spirit to the poly-polygon vs. polygon relationship.
|
|
|
|
Note that comparable to polygons, a poly-range can also
|
|
contain 'holes' - this is encoded via polygon orientation at
|
|
the poly-polygon, and via explicit flags for the poly-range.
