NAME
       Test::Memory::Cycle - Check for memory leaks and circular memory references

VERSION
       Version 1.04

SYNOPSIS
       Perl's garbage collection has one big problem: Circular references can't get cleaned up.  A circular reference can be as simple as two
       reference that refer to each other:

	   my $mom = {
	       name => "Marilyn Lester",
	   };

	   my $me = {
	       name => "Andy Lester",
	       mother => $mom,
	   };
	   $mom->{son} = $me;

       "Test::Memory::Cycle" is built on top of "Devel::Cycle" to give you an easy way to check for these circular references.

	   use Test::Memory::Cycle;

	   my $object = new MyObject;
	   # Do stuff with the object.
	   memory_cycle_ok( $object );

       You can also use "memory_cycle_exists()" to make sure that you have a cycle where you expect to have one.

FUNCTIONS
   "memory_cycle_ok( $reference, $msg )"
       Checks that $reference doesn't have any circular memory references.

   "memory_cycle_exists( $reference, $msg )"
       Checks that $reference does have any circular memory references.

   "weakened_memory_cycle_ok( $reference, $msg )"
       Checks that $reference doesn't have any circular memory references, but unlike "memory_cycle_ok" this will also check for weakened cycles
       produced with Scalar::Util's "weaken".

   "weakened_memory_cycle_exists( $reference, $msg )"
       Checks that $reference does have any circular memory references, but unlike "memory_cycle_exists" this will also check for weakened cycles
       produced with Scalar::Util's "weaken".
