C# Class Scalien.StringRangeParams

StringRangeParams is a convenient way to specify the string parameters for iteration when using Table.GetKeyIterator(StringRangeParams), Table.GetKeyValueIterator(StringRangeParams) and Table.Count(StringRangeParams).

The supported parameters are: prefix start key end key direction

StringRangeParams is convenient because is uses chaining, so you can write expressions like new StringRangeParams().Prefix(prefix).StartKey(startKey).EndKey(endKey) and it returns the StringRangeParams instance. Optionally call .Backward() to get a backward iterator.

The default values are empty strings and forward iteration.

Méthodes publiques

Méthode	Description
Backward ( ) : StringRangeParams	Iteration will proceed backwards
Count ( uint count ) : StringRangeParams	Specify the count parameter for iteration Iteration will stop after count elements.
EndKey ( string endKey ) : StringRangeParams	Specify the end key parameter for iteration Iteration will stop at end key, or the first key greater than end key.
Granularity ( uint granularity ) : StringRangeParams	Specify the granularity parameter for iteration Iteration will receive data in batches of granularity size.
Prefix ( string prefix ) : StringRangeParams	Specify the prefix parameter for iteration. Only keys starting with prefix will be returned by the iteration.
StartKey ( string startKey ) : StringRangeParams	Specify the start key parameter for iteration. Iteration will start at start key, or the first key greater than start key.
