-/**
- * This file contains minimal interfaces for the framework to access Codec2.0.
- *
- * Codec2Client is the main class that contains the following inner classes:
- * - Listener
- * - Configurable
- * - Interface
- * - Component
- *
- * Classes in Codec2Client, interfaces in Codec2.0, and  HIDL interfaces are
- * related as follows:
- * - Codec2Client <==> C2ComponentStore <==> IComponentStore
- * - Codec2Client::Listener <==> C2Component::Listener <==> IComponentListener
- * - Codec2Client::Configurable <==> [No equivalent] <==> IConfigurable
- * - Codec2Client::Interface <==> C2ComponentInterface <==> IComponentInterface
- * - Codec2Client::Component <==> C2Component <==> IComponent
- *
- * The entry point is Codec2Client::CreateFromService(), which creates a
- * Codec2Client object. From Codec2Client, Interface and Component objects can
- * be created by calling createComponent() and createInterface().
- *
- * createComponent() takes a Listener object, which must be implemented by the
- * user.
- *
- * At the present, createBlockPool() is the only method that yields a
- * Configurable object. Note, however, that Interface, Component and
- * Codec2Client are all subclasses of Configurable.

-# All text after a double hash (##) is considered a comment and is placed in
-# front of the TAG it is preceding.
-#
-# All text after a single hash (#) is considered a comment and will be ignored.

-
-# This tag specifies the encoding used for all characters in the config file
-# that follow. The default is UTF-8 which is also the encoding used for all text

-# built into libc) for the transcoding. See http://www.gnu.org/software/libiconv

-/** \ingroup API
- *
- * The Codec2 API defines the operation of data processing components and their interaction with
- * the rest of the system.
- *
- * Coding Conventions
- *
- * Mitigating Binary Compatibility.
- *
- * While full binary compatibility is not a goal of the API (due to our use of STL), we try to
- * mitigate binary breaks by adhering to the following conventions:
- *
- * - at most one vtable with placeholder virtual methods
- * - all optional/placeholder virtual methods returning a c2_status_t, with C2_OMITTED not requiring
- *   any update to input/output arguments.
- * - limiting symbol export of inline methods
- * - use of pimpl (or shared-pimpl)
- *
- * Naming
- *
- * - all classes and types prefix with C2
- * - classes for internal use prefix with _C2
- * - enum values in global namespace prefix with C2_ all caps
- * - enum values inside classes have no C2_ prefix as class already has it
- * - supporting two kinds of enum naming: all-caps and kCamelCase
- * \todo revisit kCamelCase for param-type
- *
- * Aspects
- *
- * Aspects define certain common behavior across a group of objects.
- * - classes whose name matches _C2.*Aspect
- * - only protected constructors
- * - no desctructor and copiable
- * - all methods are inline or static (this is opposite of the interface paradigm where all methods
- *   are virtual, which would not work due to the at most one vtable rule.)
- * - only private variables (this prevents subclasses interfering with the aspects.)

- * Synchronization is accomplished using event and fence objects.

- * Fences and events are shareable/copyable.

- * Fences are used in two scenarios, and all copied instances refer to the same event.
- * \todo do events need to be copyable or should they be unique?

- * acquire sync fence object: signaled when it is safe for the component or client to access
- * (the contents of) an object.
- *
- * release sync fence object: \todo

- * PARAMETERS: SETTINGs, TUNINGs, and INFOs
- * ===
- *
- * These represent miscellaneous control and metadata information and are likely copied into
- * kernel space. Therefore, these are C-like structures designed to carry just a small amount of
- * information. We are using C++ to be able to add constructors, as well as non-virtual and class
- * methods.
- *
- * ==Specification details:
- *
- * Restrictions:
- *   - must be POD struct, e.g. no vtable (no virtual destructor)
- *   - must have the same size in 64-bit and 32-bit mode (no size_t)
- *   - as such, no pointer members
- *   - some common member field names are reserved as they are defined as methods for all
- *     parameters:
- *     they are: size, type, kind, index and stream
- *
- * Behavior:
- * - Params can be global (not related to input or output), related to input or output,
- *   or related to an input/output stream.
- * - All params are queried/set using a unique param index, which incorporates a potential stream
- *   index and/or port.
- * - Querying (supported) params MUST never fail.
- * - All params MUST have default values.
- * - If some fields have "unsupported" or "invalid" values during setting, this SHOULD be
- *   communicated to the app.
- *   a) Ideally, this should be avoided.  When setting parameters, in general, component should do
- *     "best effort" to apply all settings. It should change "invalid/unsupported" values to the
- *     nearest supported values.
- *   - This is communicated to the client by changing the source values in tune()/
- *     configure().
- *   b) If falling back to a supported value is absolutely impossible, the component SHALL return
- *     an error for the specific setting, but should continue to apply other settings.
- *     TODO: this currently may result in unintended results.
- *
- * **NOTE:** unlike OMX, params are not versioned. Instead, a new struct with new param index
- * SHALL be added as new versions are required.
- *
- * The proper subtype (Setting, Info or Param) is incorporated into the class type. Define structs
- * to define multiple subtyped versions of related parameters.
- *
- * ==Implementation details:
- *
- * - Use macros to define parameters
- * - All parameters must have a default constructor
- *   - This is only used for instantiating the class in source (e.g. will not be used
- *     when building a parameter by the framework from key/value pairs.)
