        overwrite($$$)
        remove($$)

        val($$)
        get_elem_number($$)
        TEST($)

FUNCTION DOCUMENTATION

new($)

Gives you a new Ohash object.

insert($$$)

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

put($$$)

Overriden put method so that we could do our own accounting. Refer to the SUPER implementation.

overwrite($$$)

Overriden overwrite method so that we could do our own accounting. Refer to the SUPER implementation.

remove($$)

Remove an element from the hash. This just calls the SUPER 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.

get_elem_number($$)

This method will give you the sequential number of an element in the ordered hash.

TEST($)

Test suite for this module. Currently this tests creates an object, puts some data in it and then writes it out in bash format.

SUPER CLASSES
