131 .IX Title "Tie::ToObject 3"
132 .TH Tie::ToObject 3 "2008-01-17" "perl v5.8.7" "User Contributed Perl Documentation"
134 Tie::ToObject \- Tie to an existing object.
136 .IX Header "SYNOPSIS"
138 \& use Tie::ToObject;
142 \& my $stolen = tied(%something);
146 \& tie %something_else, 'Tie::ToObject', $stolen;
149 .IX Header "DESCRIPTION"
150 While \*(L"tie\*(R" in perldoc allows tying to an arbitrary object, the class in question
151 must support this in it's implementation of \f(CW\*(C`TIEHASH\*(C'\fR, \f(CW\*(C`TIEARRAY\*(C'\fR or
154 This class provides a very tie constructor that simply returns the object it
155 was given as it's first argument.
157 This way side effects of calling \f(CW\*(C`$object\->TIEHASH\*(C'\fR are avoided.
159 This is used in Data::Visitor in order to tie a variable to an already
160 existing object. This is also useful for cloning, when you want to clone the
161 internal state object instead of going through the tie interface for that
