Is a Perl method defined?
In my code, I know I can write... Code:
if ( defined &test_sub ) {
test_sub();
} else {
print "Subroutine doesn't exist";
}
This tests the existence of the test_sub subroutine without actually calling it. If, though, I replace test_sub with a package method... Code:
if ( defined &$TEST->test_sub ) {
TEST->test_sub;
} else {
print "Method doesn't exist";
}
I get Code:
Not a CODE reference at (eval 22)[/opt/perl/5.8.0/lib/perl5db.pl:17] line 2, <STDIN> line 3. Any suggestions what I'm doing wrong? |
