When creating applications using the Pro SDK, we are often executing a series of geoprocesses.
It would be useful to have the option to save the output feature class of various geoproccessing functions (Buffers, Intersects, etc.) directly to defined objects in the application code, instead of writing the results to a geodatabase. Then use these in-memory feature classes as inputs to other geoprocesses in the series.
Buffer buffer1 = new AnalysisTools.Buffer();
Buffer buffer2 = new AnalysisTools.Buffer();
IFeatureClass bufferedFc1 = geoprocessor.Execute(buffer1, null);
IFeatureClass bufferedFc2 = geoprocessor.Execute(buffer2, null);
Intersect intersect = new AnalysisTools.Intersect();
intersect.in_features = buffered1, buffered2;
intersect.out_feature_class = ... written to a geodatabase feature class
object result = geoprocessor.Execute(intersect, null);
This would increase the applications performance by eliminating the need to write the results of each geoprocess step to a geodatabase, only to be read back into the application, and finally deleted at the end of the series.
