So many lines - you normally read them from a file!
Then instead of
You save the memory with
and in this case even save the loop with
All these snippets may be pretty memory-intensive. In all these cases, the file-handle is being read in list context. So, you'd end up consuming (and storing in memory) the file data all at once.
As balajesuri has already pointed out, reading the handle in scalar context would be much better.
Hi,
I'm developing a data processing pipeline with multiple stages, with data being moved between the stages using shared memory segments. The size of the data is typically of the order of hundreds of megabytes, and there are typically a few tens of main shared memory segments each of size... (2 Replies)

je::object::array
JE::Object::Array(3pm) User Contributed Perl Documentation JE::Object::Array(3pm)NAME
JE::Object - JavaScript Array object class
SYNOPSIS
use JE;
use JE::Object::Array;
$j = new JE;
$js_array = new JE::Object::Array $j, 1, 2, 3;
$perl_arrayref = $js_array->value; # returns [1, 2, 3]
$js_array->[1]; # same as $js_array->value->[1]
"$js_array"; # returns "1,2,3"
DESCRIPTION
This module implements JavaScript Array objects.
The "@{}" (array ref) operator is overloaded and returns a tied array that you can use to modify the array object itself. The limitations
and caveats mentioned in "JE::Object/"USING AN OBJECT AS A HASH"" apply here, too.
METHODS
See JE::Types for descriptions of most of the methods. Only what is specific to JE::Object::Array is explained here.
$a = JE::Object::Array->new($global_obj, @elements)
$a = JE::Object::Array->new($global_obj, $length)
$a = JE::Object::Array->new($global_obj, @elements)
This creates a new Array object.
If the second argument is an unblessed array ref, the elements of that array become the elements of the new array object.
If there are two arguments and the second is a JE::Number, a new array is created with that number as the length.
Otherwise, all arguments starting from the second one become elements of the new array object.
$a->value
This returns a reference to an array. This is a copy of the Array object's internal array. If you want an array through which you can
modify the object, use @$a.
