Detailed Description

template<typename T>
class TfScopedVar< T >

Reset variable on exiting scope.

A TfScopedVar sets a variable to a value when created then restores its original value when destroyed. For example:

*      int func(bool x) {
*           TfScopedVar<bool> scope(x, true);  // set x to true
*           return func2(x);                   // restore x after calling func2
*      }
*
