Interface IFeatureClassLoad

All Superinterfaces:

Serializable

All Known Implementing Classes:

FeatureClass, IFeatureClassLoadProxy, RasterCatalog, TemporalRecordSet

public interface IFeatureClassLoad
extends Serializable

Provides access to the load mode of a GDB feature class.

Remarks

IFeatureClassLoad is an optional interface supported by feature classes in ArcSDE and feature classes and tables in File Geodatabase. It improves performance of data loading.

With ArcSDE, putting a feature class in load-only mode disables updating of the spatial index while data is loading. In a File Geodatabase, putting a feature class or table in load-only mode disables updating of spatial and attribute indexes while data is loading. Taking the feature class or table out of load-only mode rebuilds the indexes.

Load-only mode should only be used for bulk inserts of rows and features with an insert cursor. It should not be used for editing existing rows and features.

While a feature class or table is in load-only mode, other applications cannot work with the data. A feature class or table should be placed in load-only mode only after acquiring an exclusive schema lock on the feature class via the ISchemaLock interface.

In ArcSDE, only the owner of a table or feature class can put it into load-only mode.

The dataset extent reported by the IGeoDataset::Extent property is recalculated when a feature class is removed from LoadOnlyMode to reflect the data present in the feature class.

Product Availability

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