void DCAtomicField::add_element ( DCParameter element)

bool DCPackerInterface::has_fixed_structure ( ) const [inline, inherited]

Returns true if this field type always has the same structure regardless of the data in the stream, or false if its structure may vary.

This is almost, but not quite, the same thing as has_fixed_byte_size. The difference is that a DCSwitch may have multiple cases all with the same byte size, but they will still (presumably) have different structures, in the sense that the actual list of fields varies according to the live data.
