Definition

Namespace:
System.Data.Entity.Core.Common.CommandTrees.ExpressionBuilder.Spatial
Assembly:
EntityFramework.dll

Creates a DbFunctionExpression that invokes the canonical 'SpatialBuffer' function with the specified arguments, which must have a Edm.Geography or Edm.Geometry and Edm.Double result types. The result type of the expression is Edm.Geometry.

public static System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpression SpatialBuffer (this System.Data.Entity.Core.Common.CommandTrees.DbExpression spatialValue, System.Data.Entity.Core.Common.CommandTrees.DbExpression distance);
static member SpatialBuffer : System.Data.Entity.Core.Common.CommandTrees.DbExpression * System.Data.Entity.Core.Common.CommandTrees.DbExpression -> System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpression
<Extension()>

Parameters

spatialValue
DbExpression

An expression that specifies the spatial value.

distance
DbExpression

An expression that specifies the buffer distance.

Returns

DbFunctionExpression

A new DbFunctionExpression that returns a geometry value representing all points less than or equal to distance from spatialValue.
