Constructor & Destructor Documentation

◆ QosProvider() [1/2]

dds::core::QosProvider::QosProvider	(	const std::string &	uri,
		const std::string &	profile
	)

explicit

Constructs a new QosProvider based on the provided uri and profile.

A QosProvider instance that is instantiated with all profiles and/or QoS’s loaded from the location specified by the provided uri.

Initialization of the QosProvider will fail under the following conditions:

No uri is provided.
The resource pointed to by uri cannot be found.
The content of the resource pointed to by uri is malformed (e.g., malformed XML). When initialization fails (for example, due to a parse error or when the resource identified by uri cannot be found), then PreconditionNotMetError will be thrown.

Look here for more information.

Parameters

uri	A Uniform Resource Identifier (URI) that points to the location where the QoS profile needs to be loaded from. Currently only URI’s with a ‘file’ scheme that point to an XML file are supported. If profiles and/or QoS settings are not uniquely identifiable by name within the resource pointed to by uri, a random one of them will be stored.
profile	The name of the QoS profile within the xml file that serves as the default QoS profile for the get qos operations.

Exceptions

dds::core::Error	An internal error has occurred.
dds::core::PreconditionNotMetError	When multiple thread try to invoke the function concurrently.

◆ is_nil()

template<typename DELEGATE>

bool dds::core::Reference< DELEGATE >::is_nil ( ) const

inherited

Check if the referenced object is nil.

In other words, check if the reference is pointing to a null object.

Returns: true if the referenced object is null.

◆ operator!=() [1/2]

template<typename DELEGATE>

bool dds::core::Reference< DELEGATE >::operator!= ( const null_type nil ) const

inherited

Special operator!= used to check if this reference object does not equal the dds::core::null reference.

The non-null-check can be done like this:

if (r != dds::core::null) {
   // Use the dds reference object r
}

Returns: true if this reference is not null.

◆ operator!=() [2/2]

template<typename DELEGATE>

template<typename R >

bool dds::core::Reference< DELEGATE >::operator!= ( const R & ref ) const

inherited

Compares two Reference objects and returns true if they are not equal.

Inequality is based on the referential inequality of the object being pointed to.

Parameters

ref	the other Reference object

Returns: true when not equal

◆ operator->() [1/2]

template<typename DELEGATE>

DELEGATE* dds::core::Reference< DELEGATE >::operator-> ( )

inherited

The operator->() is provided to be able to directly invoke functions on the delegate.

The decision to provide direct access to the delegate was motivated by the need for providing a way that was not invasive with respect to the CXXDDS API and yet would allow for vendor-specific extension. Thus vendor-specific extensions can be invoked on the Reference and on all its subclasses as follows:

my_dds_entity.standard_function();

my_dds_entity->vendor_specific_extension();

Returns: a reference to delegate.

◆ operator->() [2/2]

template<typename DELEGATE>

const DELEGATE* dds::core::Reference< DELEGATE >::operator-> ( ) const

inherited

The operator->() is provided to be able to directly invoke functions on the delegate.

The decision to provide direct access to the delegate was motivated by the need for providing a way that was not invasive with respect to the CXXDDS API and yet would allow for vendor-specific extension. Thus vendor-specific extensions can be invoked on the Reference and on all its subclasses as follows:

my_dds_entity.standard_function();

my_dds_entity->vendor_specific_extension();

Returns: a reference to delegate.

◆ operator==() [1/2]

template<typename DELEGATE>

bool dds::core::Reference< DELEGATE >::operator== ( const null_type ) const

inherited

Special operator== used to check if this reference object equals the dds::core::null reference.

The null-check can be done like this:

if (r == dds::core::null) {
   // Do not use the dds reference object r in its current state
}

Returns: true if this reference is null.

◆ operator==() [2/2]

template<typename DELEGATE>

template<typename R >

bool dds::core::Reference< DELEGATE >::operator== ( const R & ref ) const

inherited

Compares two Reference objects and returns true if they are equal.

Equality is based on the referential equality of the object being pointed.

Parameters

ref	the other Reference object

Returns: true when equal
