Description copied from class: AbstractMemcachedAccessStrategy

This method is a placeholder for method signatures supplied by interfaces pulled in further down the class hierarchy.

Specified by:

putFromLoad in interface org.hibernate.cache.spi.access.RegionAccessStrategy

Specified by:

putFromLoad in class AbstractMemcachedAccessStrategy<MemcachedEntityRegion>

Throws:

org.hibernate.cache.CacheException

lockItem
