Class VersionedPut<K, V>

VersionedPut is an EntryProcessor that assumes that entry values are versioned (see Coherence Versionable interface for details) and performs an update/insert operation if and only if the version of the specified value matches the version of the corresponding value. VersionedPutAll will increment the version indicator before each value is updated.

Type parameters
