Member Function Documentation

access_scope() [1/2]

dds::core::policy::PresentationAccessScopeKind::Type dds::core::policy::Presentation::access_scope

(

)

const

Gets the access_scope kind

Returns

the access_scope kind

access_scope() [2/2]

Presentation& dds::core::policy::Presentation::access_scope

(

dds::core::policy::PresentationAccessScopeKind::Type

access_scope

)

Sets the access_scope kind

Parameters

access_scope

the access_scope kind

coherent_access() [1/2]

bool dds::core::policy::Presentation::coherent_access

(

)

const

Gets the coherent_access setting

Returns

the coherent_access setting

coherent_access() [2/2]

Presentation& dds::core::policy::Presentation::coherent_access

(

bool

coherent_access

)

Sets the coherent_access setting

Parameters

coherent_access

the coherent_access setting

GroupAccessScope()

static Presentation dds::core::policy::Presentation::GroupAccessScope ( bool  coherent_access = false, bool  ordered_access = false  )

static

Parameters

coherent_access	the coherent_access setting
ordered_access	the ordered_access setting

Returns

a Presentation QoS instance with a GROUP access_score and coherent_access and ordered_access set to the specified values

InstanceAccessScope()

static Presentation dds::core::policy::Presentation::InstanceAccessScope ( bool  coherent_access = false, bool  ordered_access = false  )

static

Parameters

coherent_access	the coherent_access setting
ordered_access	the ordered_access setting

Returns

a Presentation QoS instance with a INSTANCE access_score and coherent_access and ordered_access set to the specified values

operator!=()

template<typename D >

bool dds::core::Value< D >::operator!= ( const Value< D > &  other ) const

inherited

Compare this Value with another Value

Parameters

other

Value

Returns

true if not equal

operator->() [1/2]

template<typename D >

D* dds::core::Value< D >::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 Value and on all its subclasses as follows:

my_dds_value.standard_function();
my_dds_value->vendor_specific_extension();

Returns

a reference to delegate.

operator->() [2/2]

template<typename D >

const D* dds::core::Value< D >::operator-> ( ) const

my_dds_value->vendor_specific_extension();

Returns

a reference to delegate.

operator==()

template<typename D >

bool dds::core::Value< D >::operator== ( const Value< D > &  other ) const

inherited

Compare this Value with another Value

Parameters

other

Value

Returns

true if equal

ordered_access() [1/2]

bool dds::core::policy::Presentation::ordered_access

(

)

const

Gets the ordered_access setting

Returns

the ordered_access setting

ordered_access() [2/2]

Presentation& dds::core::policy::Presentation::ordered_access

(

bool

ordered_access

)

Sets the ordered_access setting

Parameters

ordered_access

the ordered_access setting

TopicAccessScope()

static Presentation dds::core::policy::Presentation::TopicAccessScope ( bool  coherent_access = false, bool  ordered_access = false  )

static

Parameters

coherent_access	the coherent_access setting
ordered_access	the ordered_access setting

Returns

a Presentation QoS instance with a TOPIC access_score and coherent_access and ordered_access set to the specified values
