Examples of org.geotools.validation.Validation

org.geotools.validation.Validation
Used to define a type of validation test that is performed on Features.
Each ValidationPlugIn is very specific in nature: it performs one test extermly well. This simplifies design decisions, documenation configuration and use.

The PlugIn is also required to supply some metadata to aid in its deployment, scripting, logging and execution and error recovery:
- name: user's name of validation test
- description: user's description of validation test
- priority: used to schedule validation test
- typeNames: used to connect validaiton test to transaction opperation
