Detailed Description

Class that is a built-in topic type that can be used to readily create Topics, DataReaders and DataWriters for this type without the need for code generation.

This built-in type allows for easy transfer of strings.

Constructor & Destructor Documentation

StringTopicType() [1/2]

dds::core::StringTopicType::StringTopicType

(

)

Creates topic type with an empty data string.

StringTopicType() [2/2]

dds::core::StringTopicType::StringTopicType

(

const std::string &

data

)

Creates topic type with the given string.

Member Function Documentation

data() [1/2]

const std::string& dds::core::StringTopicType::data

(

)

const

Getter function for the internal data string.

data() [2/2]

void dds::core::StringTopicType::data

(

const std::string &

data

)

Setter function for the internal data string.

operator std::string &()

dds::core::StringTopicType::operator std::string &

(

)

const

Conversion operator to a string.

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

Definition at line 99 of file Value.hpp.

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

inherited

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
