CompressionLevel

Gets/Sets the Compression Level to be used.
Declaration
public int CompressionLevel { get; set; }
Property Value
Type Description
System.Int32
Remarks

If the Compression Level is set to None then High Speed mode will always be used regardless of the input Graph and the HighSpeedModePermitted property.

If the Compression Level is set to Minimal or above then full Predicate Object lists will be used for Triples.

If the Compression Level is set to More or above then Blank Node Collections and Collection syntax will be used if the Graph contains Triples that can be compressed in that way.
