Class SerializedDVStrategy
A SpatialStrategy based on serializing a Shape stored into BinaryDocValues. This is not at all fast; it's designed to be used in conjuction with another index based SpatialStrategy that is approximated(like RecursivePrefixTreeStrategy) to add precision or eventually make more specific / advanced calculations on the per-document geometry. The serialization uses Spatial4j's BinaryCodec.

public class SerializedDVStrategy : SpatialStrategyConstructors
| Name | Description |
|---|---|
| SerializedDVStrategy(SpatialContext, String) | Constructs the spatial strategy with its mandatory arguments. |
Methods
| Name | Description |
|---|---|
| MakeDistanceValueSource(IPoint, Double) | |
| MakeFilter(SpatialArgs) | Returns a Filter that should be used with QUERY_FIRST_FILTER_STRATEGY. Use in another manner is likely to result in an System.NotSupportedException to prevent misuse because the filter can't efficiently work via iteration. |
| MakeQuery(SpatialArgs) | |
| MakeShapeValueSource() | Provides access to each shape per document as a ValueSource in which ObjectVal(Int32) returns a IShape. |
