This page is a follow up to geotools-devel discussion asking the important question: How to represent parameters that are expected to capture an interaction?
- Parameter supplying an Attribute, needs to know which Parameter is supplying the schema (so we can show a nice drop-down list)
- Parameters that are required to work together in a group
- Parameters that are exclusive (only one can be used in a group)
Here are the code examples.
Attribute and Expression
This example is interesting as both DISSOLVE and ATTRIBUTE "look up" in their group for the parameter providing a "schema". Attribute allows more than one attribute to be defined, using the same Transform Definition thing as the transform process.
