IdGenerator (Power TAC factored customer 1.8.0-SNAPSHOT API)

java.lang.Object
- org.powertac.common.IdGenerator

```
public class IdGenerator
extends Object
```
Generates numeric ID values for domain types. ID values are of the form xA+B, where x is the multiplier, A is an integer prefix, and B is the value of a counter incremented with each call. The use of a prefix allows the server to give each broker a space of ID values and prevent collisions.

public IdGenerator()

- Method Detail
  - createId
```
public static long createId()
```
    Generates a numeric ID as xA+B.
  - setPrefix
```
public static void setPrefix(int value)
```
    Each entity living in a separate process must have a different prefix value. These values are presumably set by the competition control service.
  - getPrefix
```
public static int getPrefix()
```
    Returns the id prefix - needed for testing.
  - getString
```
public static String getString(long id)
```
    Converts ID value to String as A.B.
  - getMultiplier
```
public static int getMultiplier()
```
    Returns the multiplier for an id, needed to validate id values
  - extractPrefix
```
public static int extractPrefix(long id)
```
    Returns the id prefix for the given id.
  - recycle
```
public static void recycle()
```
    Recycles the generator. This should only be used in a setting where multiple sessions are run in a single process.
