◆ invoke() [1/3]

virtual std::optional< object_ref > xtd::isynchronize_invoke::invoke ( delegate< void()> value )

pure virtual

Synchronously executes the delegate on the thread that created this object and marshals the call to the creating thread.

Parameters

method A xtd::delegate that contains a method to call, in the context of the thread for the control.

Returns: An xtd::object that represents the return value from the delegate being invoked, or null if the delegate has no return value.

Remarks: Unlike xtd::isynchronize_invoke::begin_invoke, this method operates synchronously, that is, it waits until the process completes before returning. Exceptions raised during the call are propagated back to the caller.; Use this method when calling a method from a different thread to marshal the call to the proper thread.
