CompoundOperationMap

open class CompoundOperationMap(owner: SlotMapOwner) : SlotMap, AutoCloseable

A sequence of operations run against one map. It does as little as possible: no locking, just a note of whether the map was changed, so the map underneath knows when to hand work off.

Upstream also has a locking variant for thread-safe objects. This port has none (D-3).

Constructors

constructor(owner: SlotMapOwner)

Properties

isTouched

val isTouched: Boolean

Functions

add

open override fun add(owner: SlotMapOwner?, newSlot: Slot)

Puts a slot straight in. Both its name and its index hash have to be set already. ScriptableObject normally goes through modify instead.

open override fun close()

Nothing to undo without locks.

compute

open override fun <S : Slot> compute(owner: SlotMapOwner, key: Any?, index: Int, compute: SlotMap.SlotComputer<S>): S?

Replaces what key maps to with whatever compute returns: null removes the mapping, and anything else replaces or creates it. If compute throws, nothing changes.
