`java.util.Set<java.math.BigInteger>`	`getTokensForReplacementNode(java.util.Set<java.math.BigInteger> oldTokens)`
`void`	`growingCluster(int numNewNodes)` Indicates that we are starting a new cluster of the given number of nodes, so expect that number of consecutive calls to `TokenGenerator.newToken()`.
`abstract java.math.BigInteger`	`max()`
`abstract java.math.BigInteger`	`min()`
`java.math.BigInteger`	`newToken()` Unless we're explicitly starting a new cluster or resizing by a pre-defined number of nodes, then let Cassandra decide (i.e.
`abstract java.math.BigInteger`	`range()`

`void`	`setOrigin(java.math.BigInteger shift)`
