Provides access to members of a GP Data Type.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
When To Use
The IGPDataType interface is used to define the data type for each parameter to a geoprocessing tool. Some examples of data types include FeatureClass, Table, and Raster.
The data type is an object used to specify and manage the values passed in as input to a geoprocessing function. For example, in ModelBuilder datatypes are used to determine if a given model variable is valid input to a geoprocessing tool.
Data types are used to provide a way to generate and validate the parameter values. For every data type there is a IGPValue object. IGPValue objects are the actual inputs to a geoprocessing tool.
A complete example of defining the parameter data types is available in the article, Building Geoprocessing Function Tools.
