Direct Dependencies In

API ID: CountDirectDepsIn
Languages: Any
Targets: Architectures

Number of other architectures that depend on this architecture's own entities.

Dependencies that only touch descendants are not counted. A dependent that references both this architecture and a child still counts once.

In the sample below, for "project", the only direct entity is main.cpp (api and ui are in child architectures). Only "tests/main" depends on main.cpp; "tests/api" depends on api.cpp (a descendant), so it does not count. CountDirectDepsIn is 1.

Compare to CountDepsIn, which counts those same dependents and in addition dependents that reference only descendant entities.

Consider a directory-style architecture and dependencies:

• project
  • api
    • api.cpp
  • ui
    • ui.cpp
  • main.cpp
• libraries
  • library1
    • ibrary1.cpp
  • library2
    • library2.cpp
• tests
  • main
    • main_test.cpp
  • api
    • api_test.cpp

Dependencies (with reference counts):

1. main.cpp → api.cpp (3 refs)
2. main.cpp → ui.cpp (9 refs)
3. main.cpp → library1.cpp (8 refs)
4. api.cpp → library1.cpp (6 refs)
5. ui.cpp → library2.cpp (4 refs)
6. ui.cpp → api.cpp (2 refs)
7. main_test.cpp → main.cpp (7 refs)
8. 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
