	package foo;
	use Meta::Ds::Ochash qw();

This is an object which is a hash table which can also give you a random element. Any child must inherit from Meta::Ds::Connected and thus be able to retrieve its parent.

	new($)
	insert($$$)
	remove($$)
	elem($$)
	key($$)
	val($$)
	print($$)
	get_elem_number($$)
	TEST($)

new($)

Gives you a new Ochash object.

insert($$$)

Inserts an element into the hash. This just does a Hash insert and updates the list if the hash was actually inserted.

remove($$)

Remove an element from the hash. This just calls the Meta::Ds::Hash remove and removes the element from the list if it was successful.

elem($$)

This returns a specific element in the hash.

key($$)

This returns the key with the specified number.

val($$)

This returns the value with the specified number.

print($$)

This will print the Ochash object to the specified file for you.

get_elem_number($$)

This method will retrieve the sequential number of an element.

TEST($)

Test suite for this module.
