Definition

Namespace:

System.Data.Entity.Spatial

Assembly:

EntityFramework.dll

Overloads

GetIsClosed(DbGeography)	Returns a nullable Boolean value that whether the given DbGeography value is closed, which may be null if the value does not represent a curve.
GetIsClosed(DbGeometry)	Returns a nullable Boolean value that whether the given DbGeometry value is closed, which may be null if the value does not represent a curve.

GetIsClosed(DbGeography)

Returns a nullable Boolean value that whether the given DbGeography value is closed, which may be null if the value does not represent a curve.

public abstract Nullable<bool> GetIsClosed (System.Data.Entity.Spatial.DbGeography geographyValue);

abstract member GetIsClosed : System.Data.Entity.Spatial.DbGeography -> Nullable<bool>

Public MustOverride Function GetIsClosed (geographyValue As DbGeography) As Nullable(Of Boolean)

Parameters

geographyValue

DbGeography

The geography value, which need not represent a curve.

Returns

Nullable<Boolean>

True if the given DbGeography value is closed; otherwise, false.

Exceptions

ArgumentNullException

geographyValue is null.

ArgumentException

geographyValue is not compatible with this spatial services implementation.

GetIsClosed(DbGeometry)

abstract member GetIsClosed : System.Data.Entity.Spatial.DbGeometry -> Nullable<bool>

Public MustOverride Function GetIsClosed (geometryValue As DbGeometry) As Nullable(Of Boolean)

Parameters

geometryValue

DbGeometry

The geometry value, which need not represent a curve.

Returns

Nullable<Boolean>

True if the given DbGeography value is closed; otherwise, false.

Exceptions

ArgumentNullException

geometryValue is null.

ArgumentException

geometryValue is not compatible with this spatial services implementation.
