Interface: AreaCollection
Represents a collection of areas/axis-aligned
bounding boxes for use e.g. for load prioritization. Implementations
are not expected to store all areas inserted with addAreas,
but rather some "representative box set" covering the inserted areas.
Performance will be better the fewer boxes the representative set contains,
while the effectiveness of node prioritization will suffer if the
representative set covers too much area that is not part
of the inserted boxes

Methods
addAreas()
addAreas(
boxes):void
Add areas to be covered by the representative set of this AreaCollection.
Parameters
• boxes: Iterable<Box3>
Returns
void
Defined in
packages/cad-styling/src/prioritized/AreaCollection.ts:36
areas()
areas():
Generator<Box3,any,unknown>
Return some set of boxes that cover the boxes inserted with addAreas.
It is required that each inserted box is completely covered by some
subset of boxes in the set returned from areas
Returns
Generator<Box3, any, unknown>

packages/cad-styling/src/prioritized/AreaCollection.ts:25
intersectWith()
intersectWith(
boxes):void
Alter the representative set to cover only the intersection between the representative set of this AreaCollection and the incoming boxes. Note that the intersection of two representative sets A' and B' that represent the original box sets A and B will cover the intersection between A and B, and will thus be a valid representative set for the intersection of A and B.
Parameters
• boxes: Iterable<Box3>
Returns
void
Defined in
packages/cad-styling/src/prioritized/AreaCollection.ts:45
intersectsBox()
intersectsBox(
box):boolean
Return whether the input box intersects the AreaCollection.
Parameters
• box: Box3
Returns
boolean
