MutableTriangle
kotlin.Any
   ↳ androidx.ink.geometry.Triangle
     ↳ androidx.ink.geometry.MutableTriangle

Represents a mutable triangle, defined by its three corners p0, p1 and p2 in order. See ImmutableTriangle for the immutable version.

MutableTriangle

android
Added in 1.0.0-alpha05
MutableTriangle()

Constructs a degenerate MutableTriangle with p0, p1, and p2 set to (0, 0).

MutableTriangle

android
Added in 1.0.0-alpha05
MutableTriangle(p0: MutableVec, p1: MutableVec, p2: MutableVec)

Create the MutableTriangle from three existing MutableVec instances. Note that these instances will become the internal state of this MutableTriangle, so modifications made to them directly or through setters on this MutableTriangle will modify the input MutableVec instances too. This is to allow performance-critical code to avoid any unnecessary allocations. This can be tricky to manage, especially in multithreaded code, so when calling code is unable to guarantee ownership of the nested mutable data at a particular time, it may be safest to construct this with copies of the data to give this MutableTriangle exclusive ownership of those copies.

Public functions

equals

android 
open operator fun equals(other: Any?): Boolean

Equality for MutableTriangle is defined using the order in which p0, p1 and p2 are defined. Rotated/flipped triangles with out-of-order vertices are not considered equal.

hashCode

android 
open fun hashCode(): Int

populateFrom

android
Added in 1.0.0-alpha05
fun populateFrom(input: Triangle): MutableTriangle

Fills this MutableTriangle with the values from input.

Returns the modified instance to allow chaining calls.

p0

android 
open var p0: MutableVec

One of the three points that define the Triangle.

p1

android 
open var p1: MutableVec

One of the three points that define the Triangle.

p2

android 
open var p2: MutableVec

One of the three points that define the Triangle.
