Method Detail

getReadConsistentHash

@Deprecated
ConsistentHash getReadConsistentHash()

Deprecated.

Since 11.0, to be removed in 14.0. Please use getCacheTopology() instead.

Returns:

the consistent hash used for reading.

getWriteConsistentHash

@Deprecated
ConsistentHash getWriteConsistentHash()

Deprecated.

Since 11.0, to be removed in 14.0. Please use getCacheTopology() instead.

Returns:

the consistent hash used for writing.

isAffectedByRehash

boolean isAffectedByRehash(Object key)

Tests whether a given key is affected by a rehash that may be in progress. If no rehash is in progress, this method returns false. Helps determine whether additional steps are necessary in handling an operation with a given key.

Parameters:

key - key to test

Returns:

whether a key is affected by a rehash

isRehashInProgress

boolean isRehashInProgress()

Tests whether a rehash is in progress

Returns:

true if a rehash is in progress, false otherwise

isJoinComplete

boolean isJoinComplete()

Tests whether the current instance has completed joining the cluster

Returns:

true if join is in progress, false otherwise

getCacheTopology

LocalizedCacheTopology getCacheTopology()

Returns:

the current cache topology, which includes the read and write consistent hashes.

setCacheTopology

@Deprecated
void setCacheTopology(CacheTopology cacheTopology)

Deprecated.

Internal only.

createLocalizedCacheTopology

LocalizedCacheTopology createLocalizedCacheTopology(CacheTopology cacheTopology)
