Wrap an array-like object in an iterator. An array like object must provide two methods, one which returns the number of elements, and another which returns the element at a given index.

The optional %pars hash may contain standard signal parameters as well as the following model parameters:

length => method name

length => coderef

The supplied argument will be used to determine the number of elements, via

            

              
              
$nelem = $obj->$length;
            
          

If not specified, a method with name length or __length__ or len or __len__ will be used if the object provides it.

at => method name

at => coderef

The supplied argument will be used to obtain the element at a specified index.

            

              
              
$element = $obj->$at( $index );
            
          

If not specified, a method with name at or __at__, or getitem or __getitem__ will be used if the object provides it.

The returned iterator supports the following capabilities:

current

next

prev

rewind

reset

freeze

INTERNALS
