Generic attribute from FeatureReader

Hello @erik_jan, thanks your help :)

I have a question: i would like extract the geometries and attributes after this transformer FeatureReader to work along my Workflow.

Thanks

Hi @danilo_inovacao - I guess the question is, how can you work with the attributes if you don't know what they are going to be? But if you do know what they will be, then you can use the option to expose them!

 

 

The only way to work with attributes when you don't know their name is to also read the schema with the FeatureReader so you have the information about what is available. Then you could merge that onto the main features and update the attributes using something like: @Value(attribute{x}.name) = abcd

Here is a workspace that does that. It changes the third attribute (here ParkName) to something different. But it's fairly restrictive over what it can do (eg it would always need to be the third attribute in the schema).

Hope this helps.

Use the dynamic option on the writer.

Lead both the Generic data and the Schema from the FeatureReader to the output.

And tell the output feature type to take the schema from the Schema object:

If you intend to write each feature into a destination feature type with the same name as its source feature type, you should set "fme_feature_type" to the Shapefile Name field, rather than "fme_feature_type_name".

 

"fme_feature_type_name" is an attribute of the schema feature, and the data features usually don't have "fme_feature_type_name". If you set "fme_feature_type_name" to the Shapefile Name field, the writer cannot determine destination feature type for each feature, unless you have added "fme_feature_type_name" to every feature before writing.
