Listing all methods on an object

[dhosek]

I know that I can use UNIVERSAL::can() to find out if an object supports a particular method, but I'm wondering if there's any way to get a complete list of the accessible methods on an object... so far I'm turning up blanks.

You can use Class::MOP to figure this out pretty easily.

my @methods = Class::MOP::Class->initialize('My::Package')->get_all_me
+thods;

What is in @methods is an array of Class::MOP::Method objects which you can call the following methods on:
• name - the local method name
• package_name - the package where the method is defined
• fully_qualified_name - the package name + name
• body - returns the code ref
It should be noted that unlike Class::Inspector and the newer Class::Sniff, this will honor the MRO (Method Resolution Order) you have chosen to use, so in 5.10 (or under Class::C3) it will return a correct method list if you use the c3 MRO instead of the standard dfs (depth-first-search) MRO.

See Class::Inspector for one fairly easy method...

use Class::Inspector;
use Data::Dump qw( dump );
print dump( Class::Inspector->methods( 'Foo' ) )."\n";

Also, Ovid has just written Class::Sniff, which he detailed in a series of blog posts:

1. Class::C3 Wierdness?
2. What Did I just Write?
3. Class::Sniff Now Detects "Unreachable" Methods
4. Class::Sniff Reporting and Exported "Methods"
5. Class::Sniff Now Detects "Duplicate" Methods
6. Detecting Long Methods Without PPI
7. Class::Sniff Notes

Not all of these entries relate directly to your problem, but I always find it interesting to follow the train of thought of module authors while they're initially developing a module.

A Super search where title contains all of "list", "method", "object" turns up some potentially relevant nodes, such as:

Class/Object Method Lister

Is list all subs in a package not of any use ? (found using Google search on the monastry)
