Method Detail

beginCommit

public void beginCommit(Long txid)

Specified by:

beginCommit in interface storm.trident.state.State

commit

public void commit(Long txid)

Specified by:

commit in interface storm.trident.state.State

sizeOf

public long sizeOf(K key)

Description copied from interface: SortedSetMultiMapState

Returns the numbers of values which are mapped to a given key

Specified by:

sizeOf in interface SortedSetMultiMapState<K,V>

Returns:

put

public boolean put(K key,
          SortedSetMultiMapState.ScoredValue<V> value)

Description copied from interface: SortedSetMultiMapState

Adds the specified value with the specified score to the sorted set stored at key. Stores a key-value pair in the multimap. If the specified value already exists in the sorted set, the score is updated and the element reinserted at the right position to ensure the correct ordering. If key does not exist, a new sorted set with the specified value as sole members is created, like if the sorted set was empty.

Specified by:

put in interface SortedSetMultiMapState<K,V>

Parameters:

key - key to store

value - scored value to store

Returns:

true if this set changed as a result of the call

getSorted

public List<SortedSetMultiMapState.ScoredValue<V>> getSorted(K key,
                                                    int count)

Description copied from interface: SortedSetMultiMapState

Returns the specified range of elements in the sorted set stored at key. The elements are considered to be ordered from the highest to the lowest score.

Specified by:

getSorted in interface SortedSetMultiMapState<K,V>

Parameters:

key - the key whose associated set is used

count - the maximum number of scored values returned

Returns:

getScore

public double getScore(K key,
              V value)

Description copied from interface: SortedSetMultiMapState

Returns the score of value in the sorted set at key. If value does not exist in the sorted set, or key does not exist, 0.0 is returned.

Specified by:

getScore in interface SortedSetMultiMapState<K,V>

Parameters:

key - the key whose associated set is used

value - the value whose score is searched

Returns:
