◆ GetDescription()

Status StructuredDataDarwinLog::GetDescription	(	const StructuredData::ObjectSP &	object_sp,

Get a human-readable description of the contents of the data.

In command-line LLDB, this method will be called by the Debugger instance for each structured data event generated, and the output will be printed to the LLDB console. If nothing is added to the stream, nothing will be printed; otherwise, a newline will be added to the end when displayed.

Parameters

[in]	object_sp	A shared pointer to the structured data to format.
[in]	stream	The stream where the structured data should be pretty printed.

Returns: The error if formatting the object contents failed; otherwise, success.

◆ GetEnabled()

bool StructuredDataDarwinLog::GetEnabled ( llvm::StringRef type_name ) const

overridevirtual

Returns whether the plugin's features are enabled.

This is a convenience method for plugins that can enable or disable their functionality. It allows retrieval of this state without requiring a cast.

Parameters

[in] type_name The name of the feature tag for the asynchronous structured data. This is needed for plugins that support more than one feature.

◆ HandleArrivalOfStructuredData()

void StructuredDataDarwinLog::HandleArrivalOfStructuredData	(	Process &	process,
		llvm::StringRef	type_name,
		const StructuredData::ObjectSP &	object_sp
	)

overridevirtual

Handle the arrival of asynchronous structured data from the process.

When asynchronous structured data arrives from the process monitor, it is immediately delivered to the plugin mapped for that feature if one exists. The structured data that arrives from a process monitor must be a dictionary, and it must have a string field named "type" that must contain the StructuredData feature name set as the value. This is the manner in which the data is routed to the proper plugin instance.

Parameters

[in]	process	The process instance that just received the structured data. This will always be the same process for a given instance of a plugin.
[in]	type_name	The name of the feature tag for the asynchronous structured data. Note this data will also be present in the object_sp dictionary under the string value with key "type".
[in]	object_sp	A shared pointer to the structured data that arrived. This must be a dictionary. The only key required is the aforementioned key named "type" that must be a string value containing the structured data type name.

◆ IsEnabled()

static bool lldb_private::StructuredDataDarwinLog::IsEnabled ( )

static

Return whether the DarwinLog functionality is enabled.

The DarwinLog functionality is enabled if the user explicitly enabled it with the enable command, or if the user has the setting set that controls if we always enable it for newly created/attached processes.

Returns: True if DarwinLog support is/will be enabled for existing or newly launched/attached processes.

◆ ModulesDidLoad()

void StructuredDataDarwinLog::ModulesDidLoad	(	Process &	process,
		ModuleList &	module_list
	)

overridevirtual

Allow the plugin to do work related to modules that loaded in the the corresponding process.

This method defaults to doing nothing. Plugins can override it if they have any behavior they want to enable/modify based on loaded modules.

Parameters

[in]	process	The process that just was notified of modules having been loaded. This will always be the same process for a given instance of a plugin.
[in]	module_list	The list of modules that the process registered as having just loaded. See Process::ModulesDidLoad(...).

◆ SupportsStructuredDataType()

bool StructuredDataDarwinLog::SupportsStructuredDataType ( llvm::StringRef type_name )

overridevirtual

Return whether this plugin supports the given StructuredData feature.

When Process is informed of a list of process-monitor-supported structured data features, Process will go through the list of plugins, one at a time, and have the first plugin that supports a given feature be the plugin instantiated to handle that feature. There is a 1-1 correspondence between a Process instance and a StructuredDataPlugin mapped to that process. A plugin can support handling multiple features, and if that happens, there is a single plugin instance created covering all of the mapped features for a given process.

Parameters

[in] type_name The name of the feature tag supported by a process. e.g. "darwin-log".

Returns: true if the plugin supports the feature; otherwise, false.
