◆ AnyTargetContainsModule()

bool TargetList::AnyTargetContainsModule ( Module & module )

Returns whether any module, including ones in the process of being added, contains this module.

I don't want to give direct access to these not yet added target, but for interruption purposes, we might need to ask whether this target contains this module.

		const ArchSpec &	arch,
		LoadDependentFiles	get_dependent_modules,
		lldb::PlatformSP &	platform_sp,
		lldb::TargetSP &	target_sp
	)

Create a new Target.

Same as the function above, but used when you already know the platform you will be using

References AddTargetInternal(), CreateTargetInternal(), and m_target_list_mutex.

◆ CreateTarget() [2/2]

Status TargetList::CreateTarget	(	Debugger &	debugger,

		llvm::StringRef	triple_str,
		LoadDependentFiles	get_dependent_modules,
		const OptionGroupPlatform *	platform_options,
		lldb::TargetSP &	target_sp
	)

Create a new Target.

Clients must use this function to create a Target. This allows a global list of targets to be maintained in a central location so signal handlers and other global functions can use it to locate an appropriate target to deliver asynchronous information to.

Parameters

[in]	debugger	The debugger to associate this target with
[in]	user_exe_path	The main executable file for a debug target. This value can be empty and the file can be set later using: Target::SetExecutableModule (ModuleSP&)
[in]	triple_str	A target triple string to be used for the target. This can be nullptr if the triple is not known or when attaching to a process.
[in]	get_dependent_modules	Track down the dependent modules for an executable and load those into the module list.
[in]	platform_options	A pointer to the platform options to use when creating this target. If this value is nullptr, then the currently selected platform will be used.
[out]	target_sp	A shared pointer to a target that will be filled in if this call is successful.

Returns: An error object that indicates success or failure

◆ DeleteTarget()

bool TargetList::DeleteTarget ( lldb::TargetSP & target_sp )

Delete a Target object from the list.

When clients are done with the Target objects, this function should be called to release the memory associated with a target object.

Parameters

[in] target_sp The shared pointer to a target.

Returns: Returns true if the target was successfully removed from from this target list, false otherwise. The client will be left with the last remaining shared pointer to the target in target_sp which can then be properly released.

◆ FindTargetWithExecutableAndArchitecture()

TargetSP TargetList::FindTargetWithExecutableAndArchitecture	(	const FileSpec &	exe_file_spec,
		const ArchSpec *	exe_arch_ptr = `nullptr`
	)		const

Find the target that contains has an executable whose path matches exe_file_spec, and whose architecture matches arch_ptr if arch_ptr is not nullptr.

Parameters

[in]	exe_file_spec	A file spec containing a basename, or a full path (directory and basename). If exe_file_spec contains only a filename (empty GetDirectory() value) then matching will be done solely based on the filenames and directories won't be compared. If exe_file_spec contains a filename and a directory, then both must match.
[in]	exe_arch_ptr	If not nullptr then the architecture also needs to match, else the architectures will be compared.

Returns: A shared pointer to a target object. The returned shared pointer will contain nullptr if no target objects have a executable whose full or partial path matches with a matching process ID.

◆ FindTargetWithProcessID()

TargetSP TargetList::FindTargetWithProcessID ( lldb::pid_t pid ) const

Find the target that contains a process with process ID pid.

Parameters

[in] pid The process ID to search our target list for.

Returns: A shared pointer to a target object. The returned shared pointer will contain nullptr if no target objects own a process with a matching process ID.

◆ GetBroadcasterClass()

llvm::StringRef lldb_private::TargetList::GetBroadcasterClass ( ) const

inlineoverridevirtual

This needs to be filled in if you are going to register the broadcaster with the broadcaster manager and do broadcaster class matching.

FIXME: Probably should make a ManagedBroadcaster subclass with all the bits needed to work with the BroadcasterManager, so that it is clearer how to add one.

Reimplemented from lldb_private::Broadcaster.
