Remarks

The GPParameter class is required to define and create parameters for a new geoprocessing tool. Parameters define the characteristics of the inputs and outputs to a geoprocessing tool. An instance of this object is first created. Properties are then set to define the data type, name, direction, etc.

For more information about using the GPParameter class, see Building Geoprocessing Function Tools.
