pdcomm::opcua::owned

Class

Move-only owner of one ::pdcomm_opcua_handle; base of every wrapper.

class owned

Declared in: #include <pdcomm/opcua/pdcomm_opcua.hpp>

The destructor and reset() release a non-zero handle with pdcomm_opcua_release(). A default-constructed or moved-from object is empty, and calling a member function on it throws error with #PDCOMM_OPCUA_INVALID_HANDLE.

Members

operator=

Method

Copy assignment is disabled: a handle has exactly one owner.

owned& operator=(const owned&) = delete

Declared in: #include <pdcomm/opcua/pdcomm_opcua.hpp>

operator=

Method

Releases the current handle, then takes ownership from other.

owned& operator=(owned&& other) noexcept

Declared in: #include <pdcomm/opcua/pdcomm_opcua.hpp>

Parameters

Name	Description
other	Owner to move from; it becomes empty.
