PollMessageExternalKeyConverter

java.lang.Object
- google.registry.model.poll.PollMessageExternalKeyConverter

```
public final class PollMessageExternalKeyConverter
extends java.lang.Object
```
A converter between external key strings for PollMessages (i.e. what registrars use to identify and ACK them) and VKeys to the resource.
The format of the key string is A-B as follows:
```
   A = PollMessage.id (decimal)
   B = PollMessage.eventTime (decimal, year only)
 
```
A typical poll message ID might thus look like: 10072612074-2018

- Method Detail
  - makePollMessageExternalId
```
public static java.lang.String makePollMessageExternalId(PollMessage pollMessage)
```
    Returns an external poll message ID for the given poll message.
  - parsePollMessageExternalId
```
public static VKey<PollMessage> parsePollMessageExternalId(java.lang.String externalKey)
```
    Returns a VKey to a PollMessage corresponding with the external ID.
    Note that the year field that is included at the end of the poll message isn't actually used for anything; it exists solely to create unique externally visible IDs for autorenews. We thus ignore it (for now) for backwards compatibility reasons, so that registrars can still ACK existing poll message IDs they may have lying around.
    
    Throws:
    
    PollMessageExternalKeyConverter.PollMessageExternalKeyParseException - if the external key has an invalid format.
