ITemporaryDataset Interface

Provides access to members that control temporary datasets.

When To Use

Temporary raster datasets can delete themselves if they are not referenced by any application. ITemporaryDatasetinterface supports temporary raster datasets. It is used to make temporary raster datasets permanent.


Name Description
Method IsTemporary Indicates if the dataset is temporary.
Method MakePermanent Persists this temporary dataset permanent.
Method MakePermanentAs Persists this temporary dataset to a new permanent dataset.

ITemporaryDataset.IsTemporary Method

Indicates if the dataset is temporary.

Public Function IsTemporary ( _
) As Boolean
public bool IsTemporary (

ITemporaryDataset.MakePermanent Method

Persists this temporary dataset permanent.

Public Sub MakePermanent ( _
public void MakePermanent (

ITemporaryDataset.MakePermanentAs Method

Persists this temporary dataset to a new permanent dataset.

Public Function MakePermanentAs ( _
    ByVal new_name As String, _
    ByVal Workspace As IWorkspace, _
    ByVal Format As String _
) As IDataset
public IDataset MakePermanentAs (
    string new_name,
    IWorkspace Workspace,
    string Format

Classes that implement ITemporaryDataset

Classes Description
FunctionRasterDataset A class for a function raster dataset.
RasterDataset A representation of a raster dataset on disk.


This interface is not supported by a RasterDataset instance from an ArcSDE geodatabase or a File geodatabase.

Temporary raster datasets are created by most operations performed by the Spatial Analyst Extension and also can be created using IRasterWorkspace2::CreateRasterDatasetmethod.

MakePermanent method change the status of a dataset from temporary to permanent. If the dataset is permanent, MakePermanent does nothing.

MakePermanentAs method makes the current dataset permanent by creating a new raster dataset that contains the same data. The current raster dataset will be deleted when all references to it are released. The supported output formats are same as ISaveAs.
