MutablePointer

interface MutablePointer<T> : Pointer<T> (source)

A mutable pointer points to a value in memory. It can be used to pass a value by reference. The advantage of a pointer is that it can be used to change the value of a variable in a function.

Since

0.1.0

Parameters

The type of the value the pointer points to

Inheritors

LateInitMutablePointer

Properties

value

abstract override var value: T

The value the pointer points to

Functions

chain

open fun <A> chain(transform: (T) -> Pointer<A>): Pointer<A>

Chain the value of the pointer. Creates a new pointer which will get the value on access, transform it and return it. So if you change the value of the original pointer the value of the new pointer will change too. Is the same as transform but the transform functions parameter should return a value, this function parameter should return a pointer.

chainAllowNull

open fun <A> chainAllowNull(transform: (T) -> Pointer<A?>?): Pointer<A?>

notNull

fun <T> Pointer<T?>.notNull(msg: String? = null): Pointer<T>

Make sure that the value of the pointer is not null

fun <T> Pointer<T>.register(register: PointerRegister<T>): Int

transform

open fun <A> transform(transform: (T) -> A): Pointer<A>

Transform the value of the pointer. Creates a new pointer which will get the value on access, transform it and return it. So if you change the value of the original pointer the value of the new pointer will change too.
