| void | zero (unsigned int i, unsigned int len) |
| zeros a block of bytes at the given index | |
| virtual | ~TpAttributeBlob () |
| destroys the memory buffer | |
It provides sequential write-function and random access functions to extract attribute positions. It has one pure virtual function which should be a function defining the grow policy.
