BoxAccumulator

Kotlin |Java

public final class BoxAccumulator

A helper class for accumulating the minimum bounding boxes of zero or more geometry objects. In colloquial terms, this can be used to find the smallest Box that contains a set of objects.

Summary

Public constructors
`BoxAccumulator()` Constructs an empty `BoxAccumulator`
`BoxAccumulator(@NonNull Box box)` Constructs a `BoxAccumulator`, populating the to accumulated bounding box from `box`.

Public methods
`final @NonNull BoxAccumulator`	`add(Box box)` Expands the accumulated bounding box (if necessary) such that it also contains `box`.
`final @NonNull BoxAccumulator`	`add(@NonNull PartitionedMesh mesh)` Expands the accumulated bounding box (if necessary) such that it also contains `mesh`.
`final @NonNull BoxAccumulator`	`add(BoxAccumulator other)` Expands the accumulated bounding box (if necessary) such that it also contains `other`.
`final @NonNull BoxAccumulator`	`add(@NonNull Parallelogram parallelogram)` Expands the accumulated bounding box (if necessary) such that it also contains `parallelogram`.
`final @NonNull BoxAccumulator`	`add(@NonNull Vec point)` Expands the accumulated bounding box (if necessary) such that it also contains `point`.
`final @NonNull BoxAccumulator`	`add(@NonNull Segment segment)` Expands the accumulated bounding box (if necessary) such that it also contains `segment`.
`final @NonNull BoxAccumulator`	`add(@NonNull Triangle triangle)` Expands the accumulated bounding box (if necessary) such that it also contains `triangle`.
`boolean`	`equals(Object other)`
`final Box`	`getBox()` The currently accumulated bounding box, which may be empty
`int`	`hashCode()`
`final boolean`	`isAlmostEqual( @NonNull BoxAccumulator other, @FloatRange(from = 0.0) float tolerance )` Compares this `BoxAccumulator` with `other`, and returns true if either: Both this and `other` are empty Neither this and `other` are empty, and their `box`es are almost equal per `Box.isAlmostEqual`
`final boolean`	`isEmpty()` Returns true if this `BoxAccumulator` is not empty; this is equivalent to checking if the `box` property is null.
`final @NonNull BoxAccumulator`	`populateFrom(@NonNull BoxAccumulator input)` Populates this `BoxAccumulator` with the same values contained in `input`.
`final @NonNull BoxAccumulator`	`reset()` Reset this object to have no bounds.
`@NonNull String`	`toString()`

Public constructors

BoxAccumulator

Added in 1.0.0-alpha02

public BoxAccumulator()

Constructs an empty BoxAccumulator

BoxAccumulator

Added in 1.0.0-alpha02

public BoxAccumulator(@NonNull Box box)

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

Public methods

add

Added in 1.0.0-alpha02

public final @NonNull BoxAccumulator add(Box box)

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

Returns
`@NonNull BoxAccumulator`	`this`

add

Added in 1.0.0-alpha02

public final @NonNull BoxAccumulator add(@NonNull PartitionedMesh mesh)

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

Returns
`@NonNull BoxAccumulator`	`this`

add

Added in 1.0.0-alpha02

public final @NonNull BoxAccumulator add(BoxAccumulator other)

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

Returns
`@NonNull BoxAccumulator`	`this`

add

Added in 1.0.0-alpha02

public final @NonNull BoxAccumulator add(@NonNull Parallelogram parallelogram)

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

Returns
`@NonNull BoxAccumulator`	`this`

add

Added in 1.0.0-alpha02

public final @NonNull BoxAccumulator add(@NonNull Vec point)

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

Returns
`@NonNull BoxAccumulator`	`this`

add

Added in 1.0.0-alpha02

public final @NonNull BoxAccumulator add(@NonNull Segment segment)

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

Returns
`@NonNull BoxAccumulator`	`this`

add

Added in 1.0.0-alpha02

public final @NonNull BoxAccumulator add(@NonNull Triangle triangle)

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

Returns
`@NonNull BoxAccumulator`	`this`

equals

public boolean equals(Object other)

getBox

Added in 1.0.0-alpha02

public final Box getBox()

The currently accumulated bounding box, which may be empty

hashCode

public int hashCode()

isAlmostEqual

Added in 1.0.0-alpha02

public final boolean isAlmostEqual(
    @NonNull BoxAccumulator other,
    @FloatRange(from = 0.0) float tolerance
)

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

isEmpty

Added in 1.0.0-alpha02

public final boolean isEmpty()

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.

populateFrom

Added in 1.0.0-alpha02

public final @NonNull BoxAccumulator populateFrom(@NonNull BoxAccumulator input)

Populates this BoxAccumulator with the same values contained in input.

reset

Added in 1.0.0-alpha02

public final @NonNull BoxAccumulator reset()

Reset this object to have no bounds. Returns the same instance to chain function calls.

toString

public @NonNull String toString()
