Class ShapePredicateValueSource

A boolean Lucene.Net.Queries.Function.ValueSource that compares a shape from a provided Lucene.Net.Queries.Function.ValueSource with a given Spatial4n.Core.Shapes.IShape and sees if it matches a given SpatialOperation (the predicate).

Constructors

ShapePredicateValueSource(ValueSource, SpatialOperation, IShape)

Declaration

public ShapePredicateValueSource(ValueSource shapeValuesource, SpatialOperation op, IShape queryShape)

Parameters

Type	Name	Description
Lucene.Net.Queries.Function.ValueSource	shapeValuesource	Must yield Spatial4n.Core.Shapes.IShape instances from it's ObjectVal(doc). If null then the result is false. This is the left-hand (indexed) side.
SpatialOperation	op	the predicate
Spatial4n.Core.Shapes.IShape	queryShape	The shape on the right-hand (query) side.
