             Summary: Consolidate common instances of DiscardAttributeChecker that discard an attribute set to the default value
                 Key: WFCORE-4815
                 URL: https://issues.redhat.com/browse/WFCORE-4815
             Project: WildFly Core
          Issue Type: Enhancement
          Components: Management
    Affects Versions: 11.0.0.Beta7
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro


A common transformer pattern for newly added attributes is to discard the attribute if the value is the default value, and reject if otherwise defined.

e.g.
{code:java}
builder.getAttributeBuilder()
    .setDiscard(new DiscardAttributeChecker.DiscardAttributeValueChecker(ATTRIBUTE.getDefaultValue()), ATTRIBUTE);
    .addRejectCheck(RejectAttributeChecker.DEFINED)
    ;
{code}

This common implementation can be implemented more concisely, such that a single instance can be used for any attribute.
