----------------------------------------
Summary: Need a public API get to list of available validators
Key: DAFFODIL-3034
URL: https://issues.apache.org/jira/browse/DAFFODIL-3034
Project: Daffodil
Issue Type: Bug
Components: API
Reporter: Steve Lawrence
Fix For: 4.0.0
I've found an instance of Daffodil API users that used ValidationMode.values()
to dynamically get the available validation modes. This was somewhat limited in
that it wouldn't return custom validators, but it was still kindof dynamic and
useful. But our new Validators class has nothing similar--it only has static
functions to test if a known validator exists or get a validator, but no way to
list the available validators.
We should add a new function (maybe Validators.list()) that returns a List of
all validators available via SPI.
This isn't tested, but I think the implementation can be something pretty
basic like this:
{code:java}
public static List<String> list() {
return new ArrayList<String>(impls.keySet());
}
{code}
