Infrastructure types for RTI Connext Messaging.
This section describes the sample types used for reading and writing. These types encapsulate data and related information:
Sample and WriteSample are value types. They own the data and the related information and their constructor and destructor initializes and releases the data types.
There are two parallel versions that behave as reference types and hold references to existing data and information instances:
There are different operations that provide loaned samples from the middleware. They return a connext::LoanedSamples. This container provides STL-compliant iterators.
Other convenience functions and types, useful in combination with STL algorithms are:
ValidSampleIterator< T, IsConst > connext::make_valid_sample_iterator | ( | SampleIterator< T, IsConst > | related_iterator | ) |
Creates an iterator that only returns valid samples.
This operation returns an iterator adapter that behaves as the associated connext::SampleIterator expect that it skips samples where SampleRef::info().valid_data
is false
related_iterator | A regular SampleIterator (e.g. connext::LoanedSamples::begin) that serves as the start point. |
related_iterator
or the end of the associated connext::LoanedSamples if there are no valid samples.LoanedSamples< T > connext::move | ( | LoanedSamples< T > & | ls | ) | |
throw | ( | ||||
) |
Creates a new LoanedSamples instance by moving the contents of an existing one.
The parameter object looses the ownership of the underlying samples and its state is reset as if it was default initialized. This function must be used to move any named LoanedSamples instance (lvalue) in and out of a function by-value. Using this function is not necessary if the original LoanedSamples is an rvalue. Moving is a very efficient operation and is guaranteed to not throw any exception.
ls | The LoanedSamples object that transfers its ownership of the contained samples into the returned object. After this call, ls is empty. |
