Public Types inherited from faiss::Index | |
| typedef long | idx_t |
| all indices are this type | |
same as IndexIDMap but also provides an efficient reconstruction implementation via a 2-way index
Definition at line 63 of file MetaIndexes.h.
|
overridevirtual |
Same as add_core, but stores xids instead of sequential ids
| xids | if non-null, ids to store for the vectors (size n) |
Reimplemented from faiss::IndexIDMap.
Definition at line 142 of file MetaIndexes.cpp.
|
overridevirtual |
Reconstruct a stored vector (or an approximation if lossy coding)
this function may not be defined for some indexes
| key | id of the vector to reconstruct |
| recons | reconstucted vector (size d) |
Reimplemented from faiss::Index.
Definition at line 168 of file MetaIndexes.cpp.
