DetachedObjectGraph

Platform and version requirements: Native (1.3)
class DetachedObjectGraph<T>

Detached object graph encapsulates transferrable detached subgraph which cannot be accessed externally, until it is attached with the attach extension function.

Constructors

Platform and version requirements: Native (1.3)

<init>

Creates stable pointer to object, ensuring associated object subgraph is disjoint in specified mode (TransferMode.SAFE by default). Raw value returned by asCPointer could be stored to a C variable or passed to another Kotlin machine.

DetachedObjectGraph(
    mode: TransferMode = TransferMode.SAFE, 
    producer: () -> T)

Restores detached object graph from the value stored earlier in a C raw pointer.

DetachedObjectGraph(pointer: COpaquePointer?)

Functions

Platform and version requirements: Native (1.3)

asCPointer

Returns raw C pointer value, usable for interoperability with C scenarious.

fun asCPointer(): COpaquePointer?

Extension Functions

Platform and version requirements: Native (1.3)

attach

Attaches previously detached object subgraph created by DetachedObjectGraph. Please note, that once object graph is attached, the DetachedObjectGraph.stable pointer does not make sense anymore, and shall be discarded, so attach of one DetachedObjectGraph object can only happen once.

fun <T> DetachedObjectGraph<T>.attach(): T
