4 This directory contains C++ language bindings for the Mojo Public API.
6 A number of subdirectories provide wrappers for the lower-level C APIs (in
7 subdirectories of the same name, under mojo/public/c/). Typically, these
8 wrappers provide increased convenience and/or type-safety.
10 Other subdirectories provide support (static) libraries of various sorts. In
11 this case, the organization is to have the public interface for the library in
12 defined in header files in the subdirectory itself and the implementation of the
13 library at a lower level, under a lib (sub)subdirectory. A developer should be
14 able to substitute their own implementation of any such support library, and
15 expect other support libraries, which may depend on that library, to work
21 The bindings/ subdirectory contains a support (static) library needed by the
22 code generated by the bindings generator tool (in mojo/public/tools/bindings/),
23 which translates Mojo IDL (.mojom) files into idiomatic C++ (among other
26 This library depends on the Environment library.
31 The environment/ subdirectory contains a support (static) library that
32 represents shared state needed to support the Bindings and GLES2 libraries.
34 This library depends on the Utility library.
40 The gles2/ subdirectory contains C++ wrappers (and some additional helpers) of
41 the API defined in mojo/public/c/gles2/ (which provides access to GLES2).
43 These wrappers depend on the Environment library.
48 The shell/ subdirectory contains a support (static) library that aids in writing
49 Mojo applications and interacting with the Shell service.
54 The system/ subdirectory contains C++ wrappers (and some additional helpers) of
55 the API defined in mojo/public/c/system/, which defines the basic, "core" API,
56 especially used to communicate with Mojo services.
61 The test_support/ subdirectory contains C++ wrappers of the test-only API
62 defined in mojo/public/c/test_support/. It is not meant for general use by Mojo
68 The utility/ subdirectory contains a support (static) library that provides
69 various basic functionality. Most notably, it provides an implementation of a
70 RunLoop based on MojoWaitMany() that applications may use as the basis for
71 asynchronous message processing.
