Method Detail

set

void set(K key,
         V value,
         EntryEventType eventType)

prepopulate

void prepopulate(K key,
                 V value)

Used during initial population of query cache. Initially fetched data from cluster will be written to query cache by the help of this method.

delete

void delete(Object key,
            EntryEventType eventType)

removeEntriesOf

int removeEntriesOf(int partitionId)

Scans all entries in this QueryCache to remove matching ones with supplied partitionId

Returns:

number of entries removed

getDelegate

IMap<K,V> getDelegate()

clear

void clear()

getPublisherListenerId

UUID getPublisherListenerId()

setPublisherListenerId

void setPublisherListenerId(UUID publisherListenerId)

getCacheId

String getCacheId()

Returns:

internally used ID for this query cache

reachedMaxCapacity

boolean reachedMaxCapacity()

Used to quit pre-population when max size is reached.

Returns:

true if this query cache is at its max capacity, otherwise return false

See Also:

QueryCacheConfig.isPopulate()

getExtractors

Extractors getExtractors()

Returns:

extractors of this query cache instance.

recreate

void recreate()

Recreates this query cache. Recreation steps are:

• Reset local subscribers' state, clear all cached entries
• Recreate/reset publisher (server) side resources by using this subscribers'metadata e.g. on server restart we can recreate server side resources.
