ITemporaryDataset Interface

Provides access to members that control temporary datasets.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

When To Use

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

Members

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

Classes that implement ITemporaryDataset

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

Remarks

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::CreateRasterDataset method.

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.
