Detailed Description
template<class Parser>
class senf::SafePacketParserWrapper< Parser >
Iterator re-validating Parser wrapper.
An ordinary parser will be invalidated whenever the raw data container's size is changed. This can complicate some algorithms considerably.
This wrapper will update the parsers iterator (the value returned by the i() member) on every access. This ensures that the iterator will stay valid.
- Attention
- Beware however, if you insert or remove data before the safe wrapper, the location will not be updated accordingly and therefore the parser will be invalid.
Additionally a SafePacketParserWrapper has an uninitialized state. The only allowed operations in this state are the boolean test for validity and assigning another parser.
