Detailed Description
template<typename ElementBuilder>
class rti::flat::MutableSequenceBuilder< ElementBuilder >
Builds a sequence member of variable-size elements.
- Template Parameters
-
ElementBuilder The Builder type for the elements of the sequence
To build the elements use the ElementBuilder returned by build_next(). An empty sequence can be built by calling finish() without any call to build_next().
This class doesn't enforce the sequence bound set in IDL.
The following example uses a MutableSequenceBuilder to initialize a sequence member of MyFlatMutableBuilder with two elements:
MyFlatMutableBuilder builder = rti::flat::build_data(writer);
auto seq_builder = builder.build_my_mutable_seq();
auto element_builder = seq_builder.build_next();
// ... build the first element
element_builder.finish();
element_builder = seq_builder.build_next();
// ... build the second element
element_builder.finish();
seq_builder.finish();
Member Typedef Documentation
◆ Offset
template<typename ElementBuilder>
| typedef SequenceOffset<typename ElementBuilder::Offset> rti::flat::MutableSequenceBuilder< ElementBuilder >::Offset |
The related Offset type.
Member Function Documentation
◆ build_next()
template<typename ElementBuilder>
|
inline |
Begins building the next element.
Before calling build_next() to create a new element, the application must have called finish() on the previous element Builder.
◆ finish()
template<typename ElementBuilder>
|
inline |
Finishes building the sequence.
- Returns
- An Offset to the member that has been built.
