While "tie" in perldoc allows tying to an arbitrary object, the
|
||
|
|
class in question must support this in it's implementation of
|
||
|
|
TIEHASH, TIEARRAY or whatever.
|
||
|
|
|
||
|
|
This class provides a very tie constructor that simply returns the
|
||
|
|
object it was given as it's first argument.
|
||
|
|
|
||
|
|
This way side effects of calling $object->TIEHASH are avoided.
|
||
|
|
|
||
|
|
This is used in Data::Visitor in order to tie a variable to an
|
||
|
|
already existing object. This is also useful for cloning, when you
|
||
|
|
want to clone the internal state object instead of going through
|
||
|
|
the tie interface for that variable.
