Is there a best practice for performing a put if absent operation that returns the existing value if it exists?

A two step process is used for 2.0 servers. We are making changes to the database in future versions that could do this in a single step.
WritePolicy policy = new WritePolicy();
policy.recordExistsAction = RecordExistsAction.FAIL;
try {
client.put(policy, key, new Bin("bin", "value"));
}
catch (Exception e) {
Record record = client.get(policy, key);
}
