◆ InstanceHandleSeq

typedef std::vector<InstanceHandle> dds::core::InstanceHandleSeq

A sequence of dds::core::InstanceHandle.

Function Documentation

◆ polymorphic_cast()

template<typename TO , typename FROM >

TO polymorphic_cast ( const FROM & from )

Downcasts an Entity to a subclass.

Note

Header: <dds/core/ref_traits.hpp>
Namespace: dds::core

Template Parameters

TO	The type to cast to
FROM	The type to cast from

Parameters

from	The object to cast to type `TO`

Returns: A reference to the same object from, but cast to the type TO. Both objects share ownership of the underlying entity.

For example:

using namespace dds::core;
using namespace dds::domain;
DomainParticipant participant(0);
Entity entity = participant; // Assignment to base
DomainParticipant participant2 = polymorphic_cast<DomainParticipant>(entity);
assert (participant == participant2); // Same reference
