Subject: Add libbabeltrace2 C++ interface base
X-Git-Url: http://git.efficios.com/?p=babeltrace.git;a=commitdiff_plain;h=01bf7a3a1fbc42bb8b069793619ca786f52ca6de;hp=01bf7a3a1fbc42bb8b069793619ca786f52ca6de

Add libbabeltrace2 C++ interface base

This patch adds three new C++ headers to `src/cpp-common/bt2/internal`:

`borrowed-obj.hpp`:
    Defines `bt2::internal::BorrowedObj` which wraps a libbabeltrace2
    object pointer without managing reference counting.

`shared-obj.hpp`:
    Defines `bt2::internal::SharedObj` which contains a
    `bt2::internal::BorrowedObj` instance and manages the underlying
    reference count of the libbabeltrace2 object.

Those classes are meant to be used by public classes in
`src/cpp-common/bt2`, hence their `internal` namespace.
