Determines whether the two given DbGeometry values are spatially related according to the given Dimensionally Extended Nine-Intersection Model (DE-9IM) intersection pattern.

public abstract bool Relate (System.Data.Entity.Spatial.DbGeometry geometryValue, System.Data.Entity.Spatial.DbGeometry otherGeometry, string matrix);

abstract member Relate : System.Data.Entity.Spatial.DbGeometry * System.Data.Entity.Spatial.DbGeometry * string -> bool

Public MustOverride Function Relate (geometryValue As DbGeometry, otherGeometry As DbGeometry, matrix As String) As Boolean

Parameters

geometryValue: DbGeometry

The first geometry value.

otherGeometry: DbGeometry

The geometry value that should be compared with the first geometry value for relation.

matrix: String

A string that contains the text representation of the (DE-9IM) intersection pattern that defines the relation.

Returns

Boolean

true if this geometryValue value relates to otherGeometry according to the specified intersection pattern matrix; otherwise false.

Exceptions

ArgumentNullException

geometryValue , otherGeometry or matrix is null.

ArgumentException

geometryValue or otherGeometry is not compatible with this spatial services implementation.
