""" | |
Define a modified ModuleGraph that can return its contents as | |
a TOC and in other ways act like the old ImpTracker. | |
TODO: This class, along with TOC and Tree should be in a separate module. | |
For reference, the ModuleGraph node types and their contents: | |
nodetype identifier filename | |
Script full path to .py full path to .py | |
SourceModule basename full path to .py | |
BuiltinModule basename None | |
CompiledModule basename full path to .pyc | |
Extension basename full path to .so | |
MissingModule basename None | |
Package basename full path to __init__.py | |
packagepath is ['path to package'] | |
globalnames is set of global names __init__.py defines | |
ExtensionPackage basename full path to __init__.{so,dll} | |
packagepath is ['path to package'] | |
The main extension here over ModuleGraph is a method to extract nodes | |
from the flattened graph and return them as a TOC, or added to a TOC. | |
Other added methods look up nodes by identifier and return facts | |
about them, replacing what the old ImpTracker list could do. | |

""" | |
Directed graph whose nodes represent modules and edges represent | |
dependencies between these modules. | |
This high-level subclass wraps the lower-level `ModuleGraph` class with | |
support for graph and runtime hooks. While each instance of `ModuleGraph` | |
represents a set of disconnected trees, each instance of this class *only* | |
represents a single connected tree whose root node is the Python script | |
originally passed by the user on the command line. For that reason, while | |
there may (and typically do) exist more than one `ModuleGraph` instance, | |
there typically exists only a singleton instance of this class. | |

pre-find module path hooks to the absolute paths of such hooks. See the | |

_hooks_pre_safe_import_module : ModuleHookCache | |
Dictionary mapping the fully-qualified names of all modules with | |

the `_safe_import_module()` method for details. | |
_user_hook_dirs : list | |

hooks for the current application. | |
_excludes : list | |
List of module names to be excluded when searching for dependencies. | |
_additional_files_cache : AdditionalFilesCache | |
Cache of all external dependencies (e.g., binaries, datas) listed in | |
hook scripts for imported modules. | |
_base_modules: list | |
Dependencies for `base_library.zip` (which remain the same for every | |
executable). | |
