Box

Kotlin |Java

public abstract class Box

Known direct subclasses

ImmutableBox, MutableBox

`ImmutableBox`	An immutable axis-aligned rectangle.
`MutableBox`	A mutable axis-aligned rectangle.

Represents an axis-aligned rectangle. See ImmutableBox and MutableBox for concrete classes implementing Box.

The Box interface is the read-only view of the underlying data which may or may not be mutable.

Summary

Public methods
`final @NonNull MutableVec`	`computeCenter(@NonNull MutableVec outVec)` Populates `outVec` with the center of the `Box`, and returns `outVec`.
`final void`	`computeCorners( @NonNull MutableVec outVecXMinYMin, @NonNull MutableVec outVecXMaxYMin, @NonNull MutableVec outVecXMaxYMax, @NonNull MutableVec outVecXMinYMax )` Populates the 4 output points with the corners of the `Box`.
`final boolean`	`contains(@NonNull Box otherBox)` Returns whether the other Box is contained within this Box.
`final boolean`	`contains(@NonNull Vec point)` Returns whether the given point is contained within the Box.
`final @FloatRange(from = 0.0) float`	`getHeight()` The height of the rectangle.
`final @FloatRange(from = 0.0) float`	`getWidth()` The width of the rectangle.
`abstract float`	`getXMax()` The upper bound in the `X` direction.
`abstract float`	`getXMin()` The lower bound in the `X` direction.
`abstract float`	`getYMax()` The upper bound in the `Y` direction.
`abstract float`	`getYMin()` The lower bound in the `Y` direction.
`final boolean`	`isAlmostEqual(@NonNull Box other, @FloatRange(from = 0.0) float tolerance)` Compares this `Box` with `other`, and returns true if the difference between `xMin` and other.xMin is less than `tolerance`, and likewise for `xMax`, `yMin`, and `yMax`.

Public methods

computeCenter

Added in 1.0.0-alpha02

public final @NonNull MutableVec computeCenter(@NonNull MutableVec outVec)

Populates outVec with the center of the Box, and returns outVec.

computeCorners

Added in 1.0.0-alpha02

public final void computeCorners(
    @NonNull MutableVec outVecXMinYMin,
    @NonNull MutableVec outVecXMaxYMin,
    @NonNull MutableVec outVecXMaxYMax,
    @NonNull MutableVec outVecXMinYMax
)

Populates the 4 output points with the corners of the Box. The order of the corners is: (x_min, y_min), (x_max, y_min), (x_max, y_max), (x_min, y_max)

contains

Added in 1.0.0-alpha02

public final boolean contains(@NonNull Box otherBox)

Returns whether the other Box is contained within this Box. Edges of the other Box that overlap with this one's boundary are considered to be contained.

contains

Added in 1.0.0-alpha02

public final boolean contains(@NonNull Vec point)

Returns whether the given point is contained within the Box. Points that lie exactly on the Box's boundary are considered to be contained.

getHeight

Added in 1.0.0-alpha02

public final @FloatRange(from = 0.0) float getHeight()

The height of the rectangle. This can never be negative.

getWidth

Added in 1.0.0-alpha02

public final @FloatRange(from = 0.0) float getWidth()

The width of the rectangle. This can never be negative.

getXMax

Added in 1.0.0-alpha02

public abstract float getXMax()

The upper bound in the X direction.

getXMin

Added in 1.0.0-alpha02

public abstract float getXMin()

The lower bound in the X direction.

getYMax

Added in 1.0.0-alpha02

public abstract float getYMax()

The upper bound in the Y direction.

getYMin

Added in 1.0.0-alpha02

public abstract float getYMin()

The lower bound in the Y direction.

isAlmostEqual

Added in 1.0.0-alpha02

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

Compares this Box with other, and returns true if the difference between xMin and other.xMin is less than tolerance, and likewise for xMax, yMin, and yMax.
