Field Summary

static CountModifiers	DIRTY_READ When a search for matching entries encounters an entry locked under a different uncommitted transaction, the lock is ignored and matching is performed on the uncommitted state.
static CountModifiers	EXCLUSIVE_READ_LOCK The resulting entries are locked, blocking update/remove from other transactions.
static CountModifiers	MEMORY_ONLY_SEARCH Search for matching entries in cache memory only (do not use the underlying EDS).
static CountModifiers	NONE Empty - use operation default behavior.
static CountModifiers	READ_COMMITTED When a search for matching entries encounters an entry locked under a different uncommitted transaction, the lock is honored and matching is performed on the committed state.
static CountModifiers	REPEATABLE_READ When a search for matching entries encounters an entry locked under a different uncommitted transaction, the lock is honored and the entry is skipped (if the operation is invoked with a timeout it will block until the entry will be released or the timeout expires).
