Components

An overview of source code logical components.

Intro

Logical decomposition is a representation of the organization of the main source code, where every and each file is put in exactly one logical component.

Logical Decompositions Overview

Analyzed system has 1 logical decomposition:

Logical Decomposition #1: PRIMARY

The decompositions is based on the folder structure at level 1 (relative to the source code root).

Component Sizes (Lines of Code)
The "primary" logical decomposition has 27 components.
  • 2,161 files, 287,079 LOC (100.0% vs. main code).
  • "core" is biggest, containing 77.95% of LOC.
  • "release" is smallest, containing 0.05% of LOC.
