linkInto()

void linkInto ( HeteroData< SPEC > &  prefixChain )

inline

Attach a new storage frame at the end of an existing HeteroData-chain.

Template Parameters

seg	the number of the separate data segment, must match target

Parameters

prefixChain

with seg - 1 existing chained tuple-segments

Remarks

The core function actually to extend a chain with a new segment, which should have been built using a suitable nested HeteroData::Chain constructor type. Further segments can be defined working from there, since each such constructor in turn has a member type ChainExtension

Note

Always use this strongly typed extension and access path, to prevent out-of-bounds memory access. The actual HeteroData stores no run time type information, and thus a force-cast is necessary internally to access the follow-up data tuple frames. The typing, and especially the seg template parameter used to mark each StorageFrame is the only guard-rail provided, and ensures safe data access.
