IntList

class IntList(initialCapacity: Int = 16)

Primitive-Int dynamic list. Drop-in replacement for MutableList<Int> in hot loops where boxing each Int to a JVM Integer causes meaningful GC pressure. Used for shape index buffers (outlineElements, topElements, etc.) which can hold thousands of indices and are repopulated on every geometry assemble.

Single-threaded; backing array grows by 50%-or-12 (whichever is larger) on overflow.

Functions

fun add(value: Int)

fun clear()

fun copyTo(dst: IntArray, dstOffset: Int): Int

Copies size elements into dst starting at dstOffset; returns dstOffset + size.

fun copyToReversed(dst: IntArray, dstOffset: Int): Int

Copies elements into dst in reverse order starting at dstOffset; returns dstOffset + size.

operator fun get(index: Int): Int

fun removeLast(count: Int)

Drops the trailing count elements without shrinking the backing array.

fun toIntArray(): IntArray

Returns a freshly allocated IntArray containing exactly size elements.
