public class WalkJ9PoolCommand
extends Command

Implementation of DDR extension !walkj9pool. This extension takes a J9Pool address and an optional type argument, and prints the address of each element in the pool as a runnable DDR command. The type argument is used to derive the DDR command prefix to prepend to each element's address. If not provided, the default DDR command prefix is "!j9x".
