BoxAccumulator

BoxAccumulator()

Constructs an empty BoxAccumulator

BoxAccumulator(box: Box)

Constructs a BoxAccumulator, populating the to accumulated bounding box from box.

fun add(box: Box?): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains box. If box is null, this is a no-op.

Returns the modified instance to allow chaining function calls.

fun add(mesh: PartitionedMesh): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains mesh. If mesh is empty, this is a no-op.

Returns the modified instance to allow chaining function calls.

fun add(other: BoxAccumulator?): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains other. If other is null, this is a no-op.

Returns the modified instance to allow chaining function calls.

fun add(parallelogram: Parallelogram): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains parallelogram.

Returns the modified instance to allow chaining function calls.

fun add(point: Vec): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains point.

Returns the modified instance to allow chaining function calls.

fun add(segment: Segment): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains segment.

Returns the modified instance to allow chaining function calls.

fun add(triangle: Triangle): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains triangle.

Returns the modified instance to allow chaining function calls.

fun isAlmostEqual(
    other: BoxAccumulator,
    tolerance: @FloatRange(from = 0.0) Float
): Boolean

Compares this BoxAccumulator with other, and returns true if either: Both this and other are empty Neither this and other are empty, and their boxes are almost equal per Box.isAlmostEqual

fun isEmpty(): Boolean

Returns true if this BoxAccumulator is not empty; this is equivalent to checking if the box property is null.

Note that a zero-area Box is not considered empty, as a Box contains its boundary; so isEmpty will return false even if you have added only a single point to the BoxAccumulator.

fun populateFrom(input: Box?): BoxAccumulator

Resets the BoxAccumulator instance to contain just input. If input is null, the instance will be reset to empty.

Returns the modified instance to allow chaining function calls.

A BoxAccumulator can be efficiently set to the same values as another BoxAccumulator with populateFrom(other.box).

fun reset(): BoxAccumulator

Reset this object to have no bounds.

Returns the modified instance to allow chaining function calls.

val box: Box?

The currently accumulated bounding box, which may be empty

fun BoxAccumulator.add(rect: RectF): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains rect. If rect is null, this is a no-op.

This is functionally equivalent to, but more efficient than: add(ImmutableBox.from(rect))

fun BoxAccumulator.getBounds(outRect: RectF): Boolean

Fill the given RectF with the bounds of this BoxAccumulator, returning whether or not the object was actually overwritten.

fun BoxAccumulator.add(rect: MutableRect): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains rect. If rect is empty, this is a no-op.

Returns the modified instance to allow chaining calls.

fun BoxAccumulator.add(rect: Rect): BoxAccumulator

Expands the accumulated bounding box (if necessary) such that it also contains rect. If rect is empty, this is a no-op.

Returns the modified instance to allow chaining calls.
