Handle() [4/4]

fl::task::Handle::Handle ( shared_ptr< ITaskImpl > impl )

explicit

Constructs a handle for an existing task implementation.

Parameters

impl

Task implementation. Ownership is shared: this handle, every copy of it, and the entry Scheduler::add_task keeps all hold the implementation alive, and it is destroyed when the last of them goes away. Passing nullptr yields an invalid handle that behaves exactly like a default-constructed one: is_valid() returns false, every accessor returns a default value, every mutator is a no-op, and the scheduler refuses to register it.

Note

This is public only because ITaskImpl is forward-declared.
