Detailed Description

Reset variable on exiting scope.

A TfScopedAutoVar sets a variable to a value when created then restores its original value when destroyed.

For example:

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

This differs from TfScopedVar in that it's not a template class, the value type is deduced automatically and it allocates memory on the heap. If performance is critical or memory must not be allocated then use TfScopedVar instead.
