The Perl garbage collector uses simple reference counting during the normal
|
|
execution of a program. This means that cycles or unweakened references in other
|
|
parts of code can keep an object around for longer than intended. To help avoid
|
|
this problem, the reference count of a new object from its class constructor
|
|
ought to be 1. This way, the caller can know the object will be properly
|
|
DESTROYed when it drops all of its references to it.
|
|
|
|
Test::Refcount provides two test functions to help ensure this property holds
|
|
for an object class, so as to be polite to its callers.
|
|
|
|
If the assertion fails; that is, if the actual reference count is different to
|
|
what was expected, a trace of references to the object can be printed, if Marc
|
|
Lehmann's Devel::FindRef module is installed. This may assist the developer in
|
|
finding where the references are.
