Hi Monks,
I know that In perl we can store any types of References using a single Scalar Variable;
like :-
$scale_ref = \$scalar;
$array_ref = \@array;
$hash_ref = \%hash'
I am devloping Modules which is going act as a Interface between many modules.
The requirement is as follows :-
* I want to make a Scalar Variable which has to hold only Array Reference.
For example :-
sub collect_all_users_from_tables {
$table_list = @_;
}
In the above example I want to make the $table_list to hold only Array reference.
Because as module developer I may not aware who is going to use my module. But I need to take care those
things in my module.
In othere Languages like C or C++ character pointer contain only character pointer.
I want the similaar things to be done in Perl also.
I know that this can be done in perl
But I am not aware of this. I hope monks will help me.
I need some efficient way of doing this.
This can be done by doing some explicit like
ref(@_) ne ARRAY' {
+
Carp 'Only Array can be processed';
}
Without explicit check is it possible to bring that future ?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
