Method Detail

insert

public K insert(V value,
       InsertEventFactory<K,V>... customEventFactory)
         throws InsertException

Description copied from interface: Chunk

Insert a value into this Chunk, returning the key at which the get can be retrieved later. If an EventDispatcher is set on this Chunk, then events generated by the given list of InsertEventFactories will be dispatched thereon. Additionally, events will be dispatched as generated by any InsertEventFactory previously added to the Chunk.

Specified by:

insert in interface Chunk<K,V>

Parameters:

value - the value to insert

customEventFactory - optional InsertEventFactories used to generate events for this operation.

Throws:

InsertException

query

public QueryResult<V> query(K key,
                   QueryEventFactory<K,V>... customEventFactory)
                     throws QueryException

Description copied from interface: Chunk

Query a key at this Chunk, returning a QueryResult contianing the queried values. If an EventDispatcher is set on this Chunk, then events generated by the given list of QueryEventFactories will be dispatched thereon. Additionally, events will be dispatched as generated by any QueryEventFactory previously added to the Chunk.

Specified by:

query in interface Chunk<K,V>

Parameters:

key - the key to query

customEventFactory - optional QueryEventFactories used to generate events for this operation.

Throws:

QueryException

update

public int update(K key,
         V value,
         UpdateEventFactory<K,V>... customEventFactory)
           throws UpdateException

Description copied from interface: Chunk

Update a key with a value at this Chunk, returning the number of values updated. If an EventDispatcher is set on this Chunk, then events generated by the given list of QueryEventFactories will be dispatched thereon. Additionally, events will be dispatched as generated by any UpdateEventFactory previously added to the Chunk.

Specified by:

update in interface Chunk<K,V>

Parameters:

key - the key to update

value - the value to update

customEventFactory - optional UpdateEventFactories used to generate events for this operation.

Throws:

UpdateException

Parameters:

key - the key to delete

customEventFactory - optional DeleteEventFactories used to generate events for this operation.

Throws:

DeleteException

setEventDispatcher

public void setEventDispatcher(EventDispatcher eventDispatcher)

Description copied from interface: Chunk

Set the EventDispatcher on this Chunk.

Operations on this Chunk will dispatch events to the given EventDispatcher. The events dispatched are generated by EventFactories that are either previously added to this Chunk, or else passed in as a parameter to the Chunk operation.

Specified by:

setEventDispatcher in interface Chunk<K,V>

Parameters:

eventDispatcher - The EventDispatcher to be used for events on this Chunk.
