IGPValue Interface

Provides access to members of a GPValue.

Product Availability

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

When To Use

The IGPValue interface provides access to the property and methods required to create and define a Value object.

Values are the actual inputs to a tool containing scalars or paths to the data.

An array of values is created, based on the same order of the parameter definiton of a geoprocessing tool. This array of values is then used as input to both the Validate and Execute methods of the tool.

A complete example to create a geoprocessing function tool, including the use of IGPValue, is available here: Building Geoprocessing Function Tools .
