## Arguments

`aMethod` |  | Method to call for each pointer in the hash table.

## Description

Iterate iterates over all elements in the array, calling aMethod for each pointer, or until the method returns False in its continue parameter. It returns Nil if all elements were processed, or the pointer that was being processed when aMethod returned False in the Continue parameter.
