AsyncRelayCommandTParam Class

A reusable command that encapsulates the implementation of ICommand with support for async/await. Enables instant creation of an ICommand without implementing the ICommand interface for each command. The individual Execute(TParam), ExecuteAsync(TParam) and CanExecute(TParam) members are supplied via delegates.

J# supports the use of generic APIs, but not the declaration of new ones.

JScript does not support generic types or methods.

JavaScript does not support generic types or methods.

Type Parameters

TParam: [Missing <typeparam name="TParam"/> documentation for "T:BionicCode.Utilities.Net.Core.Wpf.Generic.AsyncRelayCommand`1"]

The AsyncRelayCommandTParam type exposes the following members.

Constructors

	Name	Description
	AsyncRelayCommandTParam(Action)	Creates a new parameterless command that can always execute (CanExecute will always return true).
	AsyncRelayCommandTParam(ActionTParam)	Creates a new command that can always execute (CanExecute(TParam) always returns Copy true ).
	AsyncRelayCommandTParam(FuncTask)	Creates a new parameterless asynchronous command that can always execute (CanExecute will always return true).
	AsyncRelayCommandTParam(FuncTParam, Task)	Creates a new asynchronous command that can always execute (CanExecute(TParam) always returns Copy true ).
	AsyncRelayCommandTParam(Action, FuncBoolean)	Creates a new parameterless command.
	AsyncRelayCommandTParam(ActionTParam, PredicateTParam)	Creates a new command.
	AsyncRelayCommandTParam(FuncTask, FuncBoolean)	Creates a parameterless new asynchronous command.
	AsyncRelayCommandTParam(FuncTParam, Task, PredicateTParam)	Creates a new asynchronous command.

Methods

	Name	Description
	CanExecute	Determines whether this AsyncRelayCommand can execute. (Inherited from AsyncRelayCommand.)
	CanExecute(Object)	Determines whether this AsyncRelayCommand can execute. (Inherited from AsyncRelayCommand.)
	CanExecute(TParam)	Checks if the ICommand can execute.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Execute	Executes the ICommand on the current command target. (Inherited from AsyncRelayCommand.)
	Execute(Object)	Executes the AsyncRelayCommand on the current command target. (Inherited from AsyncRelayCommand.)
	Execute(TParam)	Executes the AsyncRelayCommand on the current command target.
	ExecuteAsync	Executes the AsyncRelayCommand on the current command target asynchronously. (Inherited from AsyncRelayCommand.)
	ExecuteAsync(Object)	Executes the AsyncRelayCommand on the current command target asynchronously. (Inherited from AsyncRelayCommand.)
	ExecuteAsync(TParam)	Executes the AsyncRelayCommand on the current command target asynchronously.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
