| Summary : Simple struct building
|
Description :
A _struct_ is a data structure that can contain values (attributes). The
values of the attributes can be set at creation time, and read and modified
at run time. This module implements a very basic and easy to use _struct_
builder.
Attributes can be anything that Perl can handle. There\'s no checking on
types. If you need _struct_s with type checking and inheritance and other
fancy stuff, use one of the many CPAN modules that implement data
structures using classes and objects. Data::Struct deals with data
structures and not objects, so I placed this module under the Data::
hierarchy.
To use Data::Struct, just use it. This will export the struct() function
that does all the work.
To define a structure, call struct() with the name of the structure and a
list of accessors to be created:
struct( \"Foo\", \"foo\", \"bar\");
which can be nicely written as:
struct Foo => qw( foo bar );
To prevent ambiguities, defining a struct requires struct() to be called in
void context.
To create an empty structure:
my $s = struct \"Foo\";
To create a structure with one or more pre-initialised attributes:
my $s = struct Foo => { foo => 3, bar => \"Hi\" };
To prevent ambiguities, creating a struct requires struct() to be called in
scalar context.
When the structure has been created, you can use accessor functions to set
and get the attributes:
print \"bar is \" . $s->bar . \"\
\"; # \"Hi\"
$s->bar = 2;
print \"bar is now \" . $s->bar . \"\
\"; # 2
