BaseDoubleCheck

abstract class BaseDoubleCheck<T>(provider: Provider<T>) : SynchronizedObject, Provider<T> , Lazy<T> (source)

A Lazy and Provider implementation that memoizes the value returned from a provider. The provider instance is released after it's called.

Modification notes:

Some semantics from the kotlin stdlib's synchronized Lazy impl are ported to here.
Uses AtomicFu's synchronized + SynchronizedObject APIs for KMP support.
The _value will eagerly return if initialized
_value is @Volatile

Constructors

constructor(provider: Provider<T>)

open override val value: T

inline fun <T, R> Provider<T>.flatMap(crossinline transform: (T) -> Provider<R>): Provider<R>

Lazily maps this Provider's value to another Provider of type R.

open operator override fun invoke(): T

open override fun isInitialized(): Boolean

inline fun <T, R> Provider<T>.map(crossinline transform: (T) -> R): Provider<R>

Lazily maps this Provider's value to another Provider of type R.

Returns a memoizing Provider instance of this provider.

Returns a memoizing Lazy instance of this provider.

inline fun <T, R, V> Provider<T>.zip(other: Provider<R>, crossinline transform: (T, R) -> V): Provider<V>

Lazily zips this Provider's value with another Provider of type R and returns a Provider of type V.
