insert($$$)
remove($$)
elem($$)
keyx($$)
valx($$)
print($$)
get_elem_number($$)
TEST($)

FUNCTION DOCUMENTATION

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.

keyx($$)

This returns the key with the specified number.

valx($$)

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.
