Detailed Description

template<typename T>
class OpenDDS::DCPS::MessageBlockHelper< T >

This helper class can be used to construct ACE message blocks from IDL sequences of octet (or compatible substitutes) and be used with the Serializer to serialize/deserialize directly into the byte buffer. The sequence must have its length set before constructing this object. T should provide a length() method which is the size of the buffer and get_buffer() which returns a pointer to the underlying byte sequence.

Constructor & Destructor Documentation

◆ MessageBlockHelper() [1/2]

template<typename T>

OpenDDS::DCPS::MessageBlockHelper< T >::MessageBlockHelper ( const T & seq )

inlineexplicit

This constructor receives an already populated OctetSeq so the write pointer is advanced
