Manual Reference Pages - JE::SCOPE (3)
associated with it. This class implements this scope chain. When a variable
is accessed the objects in the scope chain are searched till the variable
A JE::Scope object can also be used as global (JE) object. Any methods it
does not understand will be delegated to the object at the bottom of the
stack (the far end of the chain), so that $scope->null means the
same thing as $scope->->null.
Objects of this class consist of a reference to an array, the elements of
which are the objects in the chain (the first element
being the global object). (Think
of it as a stack.)
This method searches through
the scope chain, starting at the end of the array, until it
variable named by the first argument. If the second argument is
present, it sets the variable. It then returns an lvalue (a
JE::LValue object) that references the variable.
This method creates (and optionally sets the value of) a new
keyword does) and returns an lvalue.
The variable object is the first object in the scope chain
(searching from the top of the
stack) that is a call object, or $scope-> if no call object is
None. Just bless an array reference. You should not need to do
this because it is done for you by the JE and JE::Object::Function
