T - Return value type of the operation.

Parameters:

operation - The operation to execute.

Returns:

Return value of the operation.

executeBackground

<T> BackgroundOperation<T> executeBackground(Operation<T> operation)

Starts executing some code in the background.

Type Parameters:

T - Return value type of the operation.

Parameters:

operation - The operation to execute in the background.

Returns:

An object for retrieving the result of the operation later.
