get

put

void put(K key,
         V value)

validatedPut

boolean validatedPut(K key,
                     V value,
                     OIndexEngine.Validator<K,V> validator)

Puts the given value under the given key into this hash table. Validates the operation using the provided validator.

Parameters:

key - the key to put the value under.

value - the value to put.

validator - the operation validator.
