Listing all methods on an object

dhosek has asked for the wisdom of the Perl Monks concerning the following question:

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";
    We're not surrounded, we're in a target-rich environment!

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

    A user level that continues to overstate my experience :-))
