LWWDictionary(TKey, TValue) Class

LWWDictionaryTKey, TValue Class

Specialized LWWDictionaryTKey, TValue with LWWRegisterT values. LWWRegisterT relies on synchronized clocks and should only be used when the choice of value is not important for concurrent updates occurring within the clock skew. Instead of using timestamps based on DateTime.UtcNow.Ticks time it is possible to use a timestamp value based on something else, for example an increasing version number from a database record that is used for optimistic concurrency control. For first-write-wins semantics you can use the ReverseClock instead of the DefaultClock This class is immutable, i.e. "modifying" methods return a new instance.

Methods

	Name	Description
	ContainsKey	Determines current LWWDictionaryTKey, TValue contains entry with provided key.
	Equals(Object)	Determines whether the specified object is equal to the current object. (Overrides ObjectEquals(Object).)
	Equals(LWWDictionaryTKey, TValue)	TBD
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetEnumerator	TBD
	GetHashCode	Serves as the default hash function. (Overrides ObjectGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Merge(IReplicatedData)	TBD
	Merge(LWWDictionaryTKey, TValue)	TBD
	NeedPruningFrom	TBD
	Prune	TBD
	PruningCleanup	TBD
	Remove(Cluster, TKey)	Removes an entry from the map. Note that if there is a conflicting update on another node the entry will not be removed after merge.
	Remove(UniqueAddress, TKey)	Removes an entry from the map. Note that if there is a conflicting update on another node the entry will not be removed after merge.
	SetItem(Cluster, TKey, TValue, ClockTValue)	Adds an entry to the map. You can provide your clock implementation instead of using timestamps based on DateTime.UtcNow.Ticks time. The timestamp can for example be an increasing version number from a database record that is used for optimistic concurrency control.
	SetItem(UniqueAddress, TKey, TValue, ClockTValue)	Adds an entry to the map. You can provide your clock implementation instead of using timestamps based on DateTime.UtcNow.Ticks time. The timestamp can for example be an increasing version number from a database record that is used for optimistic concurrency control.
	ToString	Returns a string that represents the current object. (Overrides ObjectToString.)
	TryGetValue	Tries to return a value under provided key is such value exists.
