Could anyone kindly let me know how I can create a new FeatureClass as output from the IGPParameter. I have a requirement where I need to output a feature class with geometries. They are calcuated based on input ids. The source for the data is not part of the Input parameters.
From what I have looked into so far IGPParameter3 has a property for "Schema" which can be used to define a complete structure for the output. Below is the code I have in the ParameterInfo property.
public IArray ParameterInfo
{
get
{
....
var targetFeatureClass = (IGPParameterEdit3)CreateParameter(
"TargetFeatureClass",
"Target Points FeatureClass",
esriGPParameterDirection.esriGPParameterDirectionOutput,
esriGPParameterType.esriGPParameterTypeRequired,
(IGPDataType)new DEFeatureClassTypeClass(),
new DEFeatureClassClass(),
true);
IGPFeatureSchema outSchema = new GPFeatureSchemaClass();
outSchema.FeatureType = esriFeatureType.esriFTSimple;
outSchema.GeometryType = ESRI.ArcGIS.Geometry.esriGeometryType.esriGeometryPoint;
IFieldsEdit fieldsEdit = new FieldsClass();
IFieldEdit fieldEdit = new FieldClass();
fieldEdit.Name_2 = "ID2";
fieldEdit.Type_2 = esriFieldType.esriFieldTypeString;
fieldsEdit.AddField(fieldEdit);
IFields fields = fieldsEdit as IFields;
outSchema.AdditionalFields = fields;
targetFeatureClass.Schema = (IGPSchema)outSchema;
....
}
}
Can anyone let me know who I can use the above information to create a new FeatureClass within the Execute method. There is no dependency and I cannot use clone method.
