@defgroup api-plugin-dev Plugin development

@brief
    Shared object plugin development.

This module offers macros to create a \bt_name shared object plugin.

Behind the scenes, the <code>BT_PLUGIN_*()</code> macros of this module
create and fill global tables which are located in sections of the
shared object with specific names. The \ref api-plugin functions can
load the resulting shared object file and create corresponding
\bt_plugin objects.

See \ref guide-comp-link-plugin-so.

<h1>Plugin definition C file structure</h1>

The structure of a \bt_name plugin definition C file is as such:

<ol>
  <li>
    Start with

    @code
    BT_PLUGIN_MODULE();
    @endcode
  </li>

  <li>
    Define a \bt_name plugin with BT_PLUGIN() if the plugin's name is a
    valid C identifier, or with BT_PLUGIN_WITH_ID() otherwise.

    See \ref api-plugin-dev-custom-plugin-id "Custom plugin ID" to
    learn more about plugin IDs.

    @note
        When you use BT_PLUGIN(), the plugin's ID is <code>auto</code>.
  </li>

  <li>
    \bt_dt_opt Use any of the following macros (or their
    <code>*_WITH_ID()</code> counterpart) \em once to set the properties
    of the plugin:

    - BT_PLUGIN_AUTHOR()
    - BT_PLUGIN_DESCRIPTION()
    - BT_PLUGIN_LICENSE()
    - BT_PLUGIN_VERSION()
  </li>

  <li>
    \bt_dt_opt Use any of the following macros (or their
    <code>*_WITH_ID()</code> counterpart) \em once to set the
    initialization and finalization functions of the plugin:

    - BT_PLUGIN_INITIALIZE_FUNC()
    - BT_PLUGIN_FINALIZE_FUNC()

    A plugin's initialization function is executed when the shared
    object is loaded (see \ref api-plugin).

    A plugin's finalization function is executed when the \bt_plugin
    object is destroyed, if the initialization function (if any)
    succeeded.
  </li>

  <li>
    Use any of the following macros (or their <code>*_WITH_ID()</code>
    counterpart) to add a component class to the plugin:

    - BT_PLUGIN_SOURCE_COMPONENT_CLASS()
    - BT_PLUGIN_FILTER_COMPONENT_CLASS()
    - BT_PLUGIN_SINK_COMPONENT_CLASS()
  </li>

  <li>
    \bt_dt_opt Depending on the type of the component class of step 5,
    use any of the following macros (or their <code>*_WITH_ID()</code>
    counterpart)
    \em once to set its properties:

    <dl>
      <dt>\bt_c_src_comp_cls</dt>
      <dd>
        - BT_PLUGIN_SOURCE_COMPONENT_CLASS_DESCRIPTION()
        - BT_PLUGIN_SOURCE_COMPONENT_CLASS_HELP()
      </dd>

      <dt>\bt_c_flt_comp_cls</dt>
      <dd>
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_DESCRIPTION()
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_HELP()
      </dd>

      <dt>\bt_c_sink_comp_cls</dt>
      <dd>
        - BT_PLUGIN_SINK_COMPONENT_CLASS_DESCRIPTION()
        - BT_PLUGIN_SINK_COMPONENT_CLASS_HELP()
      </dd>
    </dl>
  </li>

  <li>
    \bt_dt_opt Depending on the type of the component class of step 5,
    use any of the following macros (or their <code>*_WITH_ID()</code>
    counterpart) to set its optional methods:

    <dl>
      <dt>Source component class</dt>
      <dd>
        - BT_PLUGIN_SOURCE_COMPONENT_CLASS_FINALIZE_METHOD()
        - BT_PLUGIN_SOURCE_COMPONENT_CLASS_GET_SUPPORTED_MIP_VERSIONS_METHOD()
        - BT_PLUGIN_SOURCE_COMPONENT_CLASS_INITIALIZE_METHOD()
        - BT_PLUGIN_SOURCE_COMPONENT_CLASS_MESSAGE_ITERATOR_CLASS_FINALIZE_METHOD()
        - BT_PLUGIN_SOURCE_COMPONENT_CLASS_MESSAGE_ITERATOR_CLASS_INITIALIZE_METHOD()
        - BT_PLUGIN_SOURCE_COMPONENT_CLASS_OUTPUT_PORT_CONNECTED_METHOD()
        - BT_PLUGIN_SOURCE_COMPONENT_CLASS_QUERY_METHOD()
      </dd>

      <dt>Filter component class</dt>
      <dd>
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_FINALIZE_METHOD()
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_GET_SUPPORTED_MIP_VERSIONS_METHOD()
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_INITIALIZE_METHOD()
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_INPUT_PORT_CONNECTED_METHOD()
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_MESSAGE_ITERATOR_CLASS_FINALIZE_METHOD()
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_MESSAGE_ITERATOR_CLASS_INITIALIZE_METHOD()
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_OUTPUT_PORT_CONNECTED_METHOD()
        - BT_PLUGIN_FILTER_COMPONENT_CLASS_QUERY_METHOD()
      </dd>

      <dt>Sink component class</dt>
      <dd>
        - BT_PLUGIN_SINK_COMPONENT_CLASS_FINALIZE_METHOD()
        - BT_PLUGIN_SINK_COMPONENT_CLASS_GET_SUPPORTED_MIP_VERSIONS_METHOD()
        - BT_PLUGIN_SINK_COMPONENT_CLASS_GRAPH_IS_CONFIGURED_METHOD()
        - BT_PLUGIN_SINK_COMPONENT_CLASS_INITIALIZE_METHOD()
        - BT_PLUGIN_SINK_COMPONENT_CLASS_INPUT_PORT_CONNECTED_METHOD()
        - BT_PLUGIN_SINK_COMPONENT_CLASS_QUERY_METHOD()
      </dd>
    </dl>
  </li>
</ol>

You can repeat steps 5 to 7 to add more than one component class to a
given plugin.

See \ref example-simple-plugin-def-file for a concrete example of how
to use the macros of this module.

<h1>\anchor api-plugin-dev-custom-plugin-id Custom plugin ID</h1>

The BT_PLUGIN() macro defines a plugin with a specific name and the
ID <code>auto</code>.

All the <code>BT_PLUGIN_*()</code> macros which do not end with
<code>_WITH_ID</code> refer to the <code>auto</code> plugin.

There are two situations which demand that you use a custom plugin ID:

- You want more than one plugin contained in your shared object file.

  Although the \bt_name project does not recommend this, it is possible.
  This is why bt_plugin_find_all_from_file() returns a \bt_plugin_set
  instead of a single \bt_plugin.

  In this case, each plugin of the shared object needs its own, unique
  ID.

- You want to give the plugin a name which is not a valid C identifier.

  The BT_PLUGIN() macro accepts a C identifier as the plugin name, while
  the BT_PLUGIN_WITH_ID() accepts a C identifier for the ID and a C
  string for the name.

To define a plugin with a specific ID, use BT_PLUGIN_WITH_ID(), for
example:

@code
BT_PLUGIN_WITH_ID(my_plugin_id, "my-plugin-name");
@endcode

Then, use the <code>BT_PLUGIN_*_WITH_ID()</code> macros to refer to
this specific plugin, for example:

@code
BT_PLUGIN_AUTHOR_WITH_ID(my_plugin_id, "Patrick Bouchard");
@endcode

@note
    @parblock
    You can still use the <code>auto</code> ID with BT_PLUGIN_WITH_ID()
    to use the simpler macros afterwards while still giving the plugin a
    name which is not a valid C identifier, for example:

    @code
    BT_PLUGIN_WITH_ID(auto, "my-plugin-name");
    BT_PLUGIN_AUTHOR("Patrick Bouchard");
    @endcode
    @endparblock

<h1>Custom component class ID</h1>

The BT_PLUGIN_SOURCE_COMPONENT_CLASS(),
BT_PLUGIN_FILTER_COMPONENT_CLASS(), and
BT_PLUGIN_SINK_COMPONENT_CLASS() add a component class with a specific
name to the plugin having the ID <code>auto</code>.

The name you pass to those macros must be a valid C identifier and it
also serves as the component class's ID within the <code>auto</code>
plugin.

There are two situations which demand that you use a custom component
class ID:

- You want to add the component class to a specific plugin (other than
  <code>auto</code>, if you have more than one).

- You want to give the component class a name which is not a valid C
  identifier.

  The <code>BT_PLUGIN_*_COMPONENT_CLASS_WITH_ID()</code> macros accept a
  C identifier for the component class ID and a string for its name.

For a given plugin and for a given component class type, all component
class IDs must be unique.

To add a component class having a specific ID to a plugin,
use the BT_PLUGIN_SOURCE_COMPONENT_CLASS_WITH_ID(),
BT_PLUGIN_FILTER_COMPONENT_CLASS_WITH_ID(), and
BT_PLUGIN_SINK_COMPONENT_CLASS_WITH_ID() macros, for example:

@code
BT_PLUGIN_SOURCE_COMPONENT_CLASS_WITH_ID(my_plugin_id, my_comp_class_id,
    "my-source", my_source_iter_next);
@endcode

@note
    @parblock
    The <code>BT_PLUGIN_*_COMPONENT_CLASS_WITH_ID()</code> macros
    specify the ID of the plugin to which to add the component class.

    If you use the BT_PLUGIN() macro to define your plugin, then its
    ID is <code>auto</code>:

    @code
    BT_PLUGIN_SOURCE_COMPONENT_CLASS_WITH_ID(auto, my_comp_class_id,
        "my-source", my_source_iter_next);
    @endcode
    @endparblock

Then, use the <code>BT_PLUGIN_*_COMPONENT_CLASS_*_WITH_ID()</code>
macros to refer to this specific component class, for example:

@code
BT_PLUGIN_SOURCE_COMPONENT_CLASS_FINALIZE_METHOD_WITH_ID(my_plugin_id,
    my_comp_class_id, my_source_finalize);
@endcode
