A thread-safe, lazily and asynchronously evaluated value factory.

Public Class AsyncLazy(Of T)

Type Parameters

T

The type of value generated by the value factory.

Inheritance: Object
AsyncLazy<T>

Remarks

This class does not itself carry any resources needful of disposing. But the value factory may produce a value that needs to be disposed of, which is why this class carries a DisposeValueAsync() method but does not implement IDisposable.

Constructors

AsyncLazy<T>(Func<Task<T>>, JoinableTaskFactory)

Initializes a new instance of the AsyncLazy<T> class.

Properties

IsValueCreated	Gets a value indicating whether the value factory has been invoked.
IsValueDisposed	Gets a value indicating whether DisposeValue() has already been called.
IsValueFactoryCompleted	Gets a value indicating whether the value factory has been invoked and has run to completion.
SuppressRecursiveFactoryDetection	Gets a value indicating whether to suppress detection of a value factory depending on itself.

Methods

DisposeValue()	Disposes of the lazily-initialized value if disposable, and causes all subsequent attempts to obtain the value to fail.
DisposeValueAsync()	Disposes of the lazily-initialized value if disposable, and causes all subsequent attempts to obtain the value to fail.
GetValue()	Gets the lazily computed value.
GetValue(CancellationToken)	Gets the lazily computed value.
GetValueAsync()	Gets the task that produces or has produced the value.
GetValueAsync(CancellationToken)	Gets the task that produces or has produced the value.
SuppressRelevance()	Marks the code that follows as irrelevant to the receiving AsyncLazy<T> value factory.
ToString()	Renders a string describing an uncreated value, or the string representation of the created value.
