List of locateOwners() Examples

Examples of locateOwners()

org.infinispan.distribution.ch.ConsistentHash.locateOwners()
Finds all the owners of a key. The first element in the returned list is the primary owner. @param key key to locate @return An unmodifiable list of addresses where the key resides.Will never be {@code null}, and it will always have at least 1 element.
