Writer Feature Type Parameters

Just like writers, feature types have their own set of parameters that control how that feature type (layer/table) is being written. These parameters appear both in the Parameter Editor window and in the Feature Type Properties dialog:

There are general parameters that appear for every feature type, but some feature types have additional parameters below that.

The important thing is that these parameters only apply to a single feature type, whereas a writer parameter would apply to all feature types.

For example, the above screenshot is from a PostGIS database feature type with a parameter to define the Operation Type. This operation can be Insert, Update, or Delete. This is a Feature Type parameter because each table might require a different type of operation; for example I want to insert records into table A, but delete records from table B.

Conversely, there is no password parameter for this database table, because authentication applies to the entire database, not the individual tables, so authentication parameters are at the writer level (or in a database connection).

As with writers, writer feature type parameters vary by format, and some formats have no extra parameters at all at this level.
