6 pmeth - show a Perl class's methods
7
9 Given a class name, print out all methods available to that class. It
10 does this by loading in the class module, and walking its symbol table
11 and those of its ancestor classes. A regular method call shows up
12 simply:
13 $ pmeth IO::Socket | grep '^con'
15 confess
16 configure
17 connect
18 connected
19 But one that came from else where is noted with one or more "via"
21 notations:
22 DESTROY via IO::Handle
24 export via Exporter via IO::Handle
25 A base-class method that is unavailable due to being hidden by a close
27 derived-class method by the same name (but accessible via SUPER::) is
28 indicated by a leading "[overridden]" before it:
29 [overridden] new via IO::Handle
31 Constants declared via constant have a leading "[constant]" added to
33 the output, but XS "define"'s are not yet so flagged.

155 Perl makes no distinction between functions, procedures, and methods,
156 nor whether they are public or nominally private, nor whether a method
157 is nominally a class method, an object method, or both. They all show
158 up as subs in the package namespace. So if your class says "use Carp",
159 you just polluted your namespace with things like croak() and
160 confess(), which will appear to be available as method calls on objects
161 of your class.
