Detailed Description

Tiny mix-in that exposes the backend-native handle behind a node.

Transport backends commonly inherit from both AbstractNode and the matching NodeImpl subclass. get_native_handle() returns an std::any wrapping the native object (for instance a DDS DataWriter pointer) so advanced users can interact with backend internals without leaking transport types through the rest of the VLink API.

Note

The base implementation returns an std::any holding nullptr; the caller must std::any_cast to the expected backend type.

Member Function Documentation

get_native_handle()

virtual std::any vlink::AbstractNode::get_native_handle ( ) const

virtual

Returns the backend-native handle wrapped in an std::any.

Backends override this method to expose, for example, a DDS DataWriter or DataReader pointer. Callers must std::any_cast the result.

Returns

Backend handle, or nullptr-bearing std::any in the base.
