public class NumberedHashToks
extends NamedHashToks

This class provides an implementation for the primitive \hashtoks. It sets the named pair register to the value given, and as a side effect all prefixes are zeroed.

All features are inherited from hashtoks. Just the key has to be provided under which this hashtoks has to be stored. This key is constructed from the name, a hash mark and the running number.

Example

 \hashtoks1{ {key1}{value1} {key2}{value2} {key3}{value3} ...}
 \myhash7={ {key1}{value1} {key2}{value2} {key3}{value3} ...}
