Detailed Description

Loads a script-interpreter runtime into the current process before its plugin is dlopened.

Lives outside the PluginManager because plugin registration itself depends on the runtime's symbols already being resolvable. Subclasses encode a single language's resolution policy (search order, env-var overrides, platform candidates).

Member Function Documentation

Get()

llvm::Expected< ScriptInterpreterRuntimeLoader & > lldb_private::ScriptInterpreterRuntimeLoader::Get ( lldb::ScriptLanguage language )

static

Returns the loader for language.

Returns an Error when the language has no dynamic loader (currently every language except Python) or when support for it was not compiled in.

GetLoadedPath()

virtual llvm::Expected< llvm::StringRef > lldb_private::ScriptInterpreterRuntimeLoader::GetLoadedPath ( )

pure virtual

Absolute path of the loaded runtime, for diagnostics.

The success value is empty when the runtime was already in the process. Drives the load on first call.

IsLoaded()

virtual bool lldb_private::ScriptInterpreterRuntimeLoader::IsLoaded ( )

pure virtual

True if the runtime is currently mapped into the process.

Load()

virtual llvm::Error lldb_private::ScriptInterpreterRuntimeLoader::Load ( )

pure virtual

Resolves the runtime so the script interpreter plugin's undefined symbols can bind.

The first call drives the search and subsequent calls return the cached outcome. Returns success when the runtime is already in the process or has been loaded.
