Member Function Documentation
| virtual int digest::insert | ( | int | item, | |
| int | suppress = 1 | |||
| ) | [pure virtual] |
inserts an item
- Parameters:
-
item the item to insert suppress when feasible, tells the filter whether to suppress dropping values
- Returns:
- returning the lowest sequence number remaining in the digest (even after truncation)
Implemented in bitmap_digest.
| virtual void digest::serialize | ( | unsigned char * | buffer | ) | [pure virtual] |
serializes the digest into the buffer
- Warning:
- if the digest is to be continue being used, this should be replaced with basic mace serialization.
Implemented in bitmap_digest.
| virtual void digest::import | ( | unsigned char * | buffer | ) | [pure virtual] |
deserializes the buffer into the digest
- Warning:
- if the digest is to be continue being used, this should be replaced with basic mace serialization.
Implemented in bitmap_digest.
