>>>>> Structured
>>>>> >>> +Data plugins.  See the DarwinLog.md doc for a description of one
>>>>> >>> +such plugin that makes use of this feature.
>>>>> >>> +
>>>>> >>> +## StructuredDataPlugin
>>>>> >>> +
>>>>> >>> +StructuredDataPlugin instances have the following characteristics:
>>>>> >>> +
>>>>> >>> +* Each plugin instance is bound to a single Process instance.
>>>>> >>> +
>>>>> >>> +* Each StructuredData feature has a type name that identifies the
>>>>> >>> +  feature. For instance, the type name for the DarwinLog feature
>>>>> is
>>>>> >>> +  "DarwinLog". This feature type name is used in various places.
>>>>> >>> +
>>>>> >>> +* The process monitor reports the list of supported StructuredData
>>>>> >>> +  features advertised by the process monitor. Process goes
>>>>> through the
>>>>> >>> +  list of supported feature type names, and asks each known
>>>>> >>> +  StructuredDataPlugin if it can handle the feature. The first
>>>>> plugin
>>>>> >>> +  that supports the feature is mapped to that Process instance for
>>>>> >>> +  that feature.  Plugins are only mapped when the process monitor
>>>>> >>> +  advertises that a feature is supported.
>>>>> >>> +
>>>>> >>> +* The feature may send asynchronous messages in StructuredData
>>>>> format
>>>>> >>> +  to the Process instance. Process instances route the
>>>>> asynchronous
>>>>> >>> +  structured data messages to the plugin mapped to that feature
>>>>> type,
>>>>> >>> +  if one exists.
>>>>> >>> +
>>>>> >>> +* Plugins can request that the Process instance forward on
>>>>> >>> +  configuration data to the process monitor if the plugin
>>>>> needs/wants
>>>>> >>> +  to configure the feature. Plugins may call the new Process
>>>>> method
>>>>> >>> +
>>>>> >>> +  ```C++
>>>>> >>> +  virtual Error
>>>>> >>> +  ConfigureStructuredData(const ConstString &type_name,
>>>>> >>> +                          const StructuredData::ObjectSP
>>>>> &config_sp)
>>>>> >>> +  ```
>>>>> >>> +
>>>>> >>> +  where type_name is the feature name and config_sp points to the
>>>>> >>> +  configuration structured data, which may be nullptr.
>>>>> >>> +
>>>>> >>> +* Plugins for features present in a process are notified when
>>>>> modules
>>>>> >>> +  are loaded into the Process instance via this
>>>>> StructuredDataPlugin
>>>>> >>> +  method:
>>>>> >>> +
>>>>> >>> +  ```C++
>>>>> >>> +  virtual void
>>>>> >>> +  ModulesDidLoad(Process &process, ModuleList &module_list);
>>>>> >>> +  ```
>>>>> >>> +
>>>>> >>> +* Plugins may optionally broadcast their received structured data
>>>>> as
>>>>> >>> +  an LLDB process-level event via the following new Process call:
>>>>> >>> +
>>>>> >>> +  ```C++
>>>>> >>> +  void
>>>>> >>> +  BroadcastStructuredData(const StructuredData::ObjectSP
>>>>> &object_sp,
>>>>> >>> +                          const lldb::StructuredDataPluginSP
>>>>> >>> &plugin_sp);
>>>>> >>> +  ```
>>>>> >>> +
>>>>> >>> +  IDE clients might use this feature to receive information about
>>>>> the
>>>>> >>> +  process as it is running to monitor memory usage, CPU usage, and
>>>>> >>> +  logging.
>>>>> >>> +
>>>>> >>> +  Internally, the event type created is an instance of
>>>>> >>> +  EventDataStructuredData.
>>>>> >>> +
>>>>> >>> +* In the case where a plugin chooses to broadcast a received
>>>>> >>> +  StructuredData event, the command-line LLDB Debugger instance
>>>>> >>> +  listens for them. The Debugger instance then gives the plugin an
>>>>> >>> +  opportunity to display info to either the debugger output or
>>>>> error
>>>>> >>> +  stream at a time that is safe to write to them. The plugin can
>>>>> >>> +  choose to display something appropriate regarding the structured
>>>>> >>> +  data that time.
>>>>> >>> +
>>>>> >>> +* Plugins can provide a ProcessLaunchInfo filter method when the
>>>>> >>> +  plugin is registered.  If such a filter method is provided, then
>>>>> >>> +  when a process is about to be launched for debugging, the filter
>>>>> >>> +  callback is invoked, given both the launch info and the
>>>>> target.  The
>>>>> >>> +  plugin may then alter the launch info if needed to better
>>>>> support
>>>>> >>> +  the feature of the plugin.
>>>>> >>> +
>>>>> >>> +* The plugin is entirely independent of the type of
>>>>> Process-derived
>>>>> >>> +  class that it is working with. The only requirements from the
>>>>> >>> +  process monitor are the following feature-agnostic elements:
>>>>> >>> +
>>>>> >>> +  * Provide a way to discover features supported by the process
>>>>> >>> +    monitor for the current process.
>>>>> >>> +
>>>>> >>> +  * Specify the list of supported feature type names to Process.
>>>>> >>> +    The process monitor does this by calling the following new
>>>>> >>> +    method on Process:
>>>>> >>> +
>>>>> >>> +    ```C++
>>>>> >>> +    void
>>>>> >>> +    MapSupportedStructuredDataPlugins(const StructuredData::Array
>>>>> >>> +                                      &supported_type_names)
>>>>> >>> +    ```
>>>>> >>> +
>>>>> >>> +    The supported_type_names specifies an array of string entries,
>>>>> >>> +    where each entry specifies the name of a StructuredData
>>>>> feature.
>>>>> >>> +
>>>>> >>> +  * Provide a way to forward on configuration data for a feature
>>>>> type
>>>>> >>> +    to the process monitor.  This is the manner by which LLDB can
>>>>> >>> +    configure a feature, perhaps based on settings or commands
>>>>> from
>>>>> >>> +    the user.  The following virtual method on Process (described
>>>>> >>> +    earlier) does the job:
>>>>> >>> +
>>>>> >>> +    ```C++
>>>>> >>> +    virtual Error
>>>>> >>> +    ConfigureStructuredData(const ConstString &type_name,
>>>>> >>> +                            const StructuredData::ObjectSP
>>>>> &config_sp)
>>>>> >>> +    ```
>>>>> >>> +
>>>>> >>> +  * Listen for asynchronous structured data packets from the
>>>>> process
>>>>> >>> +    monitor, and forward them on to Process via this new Process
>>>>> >>> +    member method:
>>>>> >>> +
>>>>> >>> +    ```C++
>>>>> >>> +    bool
>>>>> >>> +    RouteAsyncStructuredData(const StructuredData::ObjectSP
>>>>> object_sp)
>>>>> >>> +    ```
>>>>> >>> +
>>>>> >>> +* StructuredData producers must send their top-level data as a
>>>>> >>> +  Dictionary type, with a key called 'type' specifying a string
>>>>> value,
>>>>> >>> +  where the value is equal to the StructuredData feature/type name
>>>>> >>> +  previously advertised. Everything else about the content of the
>>>>> >>> +  dictionary is entirely up to the feature.
>>>>> >>> +
>>>>> >>> +* StructuredDataPlugin commands show up under 'plugin
>>>>> structured-data
>>>>> >>> +  plugin-name'.
>>>>> >>> +
>>>>> >>> +* StructuredDataPlugin settings show up under
>>>>> >>> +  'plugin.structured-data.{plugin-name}.
