Major Dependencies In is one of the source-code metrics Understand computes across 17+ languages — browse them in the GUI, export and track them, or script them with the Python API.
Major Dependencies In
API ID: CountMajorDepsInLanguages: Any
Targets: Architectures
Number of higher-level architectures that depend on this one when sibling dependents are grouped under their parent.
In the sample below, both "tests/main" and "tests/api" depend on "project", but they are grouped into their parent "tests" and so count as 1 dependency here, in contrast to CountDepsIn which counts them separately as 2.
Consider a directory-style architecture and dependencies:
- project
- api
- api.cpp
- ui
- ui.cpp
- main.cpp
- api
- libraries
- library1
- ibrary1.cpp
- library2
- library2.cpp
- library1
- tests
- main
- main_test.cpp
- api
- api_test.cpp
- main
Dependencies (with reference counts):
- main.cpp → api.cpp (3 refs)
- main.cpp → ui.cpp (9 refs)
- main.cpp → library1.cpp (8 refs)
- api.cpp → library1.cpp (6 refs)
- ui.cpp → library2.cpp (4 refs)
- ui.cpp → api.cpp (2 refs)
- main_test.cpp → main.cpp (7 refs)
- api_test.cpp → api.cpp (5 refs)
For project, the metrics are:
| Metric | Value |
|---|---|
| CountDepsIn | 2 |
| CountDepsOut | 2 |
| CountDepRefsIn | 12 |
| CountDepRefsOut | 18 |
| CountDirectDepsIn | 1 |
| CountDirectDepsOut | 3 |
| CountDirectDepRefsIn | 7 |
| CountDirectDepRefsOut | 20 |
| CountMajorDepsIn | 1 |
| CountMajorDepsOut | 1 |
