Creates the HashStatistic.
Destroys the HashStatistic.
double avgEntriesPerHash() const;
Returns the average number of entries per position in the Hashtable, the higher this value the less efficient performs hashing. If a large value is returned and getNumberOfZeroPositions also returns a large value, this indicates an inefficient hashing function. If the number of zero entries is low, resizing the HashTable, should be enough to improve performance
double avgEntriesPerHashExclZeroEntries() const;
Same as getAvgEntriesPerHash but hash values that contain no entry are ignored, getAvgEntriesPerHashExclZeroEntries >= getAvgEntriesPerHash will always be true.
const std::vector < UInt32 > detailedEntriesPerHash() const;
Will either be an empty vector or will contain for each possible hash value, the number of entries currently stored
UInt32 maxEntriesPerHash() const;
Returns the maximum number of entries per hash value found in the current table.
UInt32 maxPositionsOfTable() const;
Returns the maximum number of different hash values possible for the table
UInt32 numberOfEntries() const;
Returns the total number of entries currently stored in the HashTable
UInt32 numberOfZeroPositions() const;
Returns the number of hash positions that contain no entry.
std::string toString() const;
Converts the whole data structure into a string.
