## 🏗️ Architecture & Design Patterns

### Core Design Principles
CoreLib follows a **utility-class pattern** where most functionality is exposed through static methods:

        verify(mockDir, times(3)).getPath();
        verifyNoMoreInteractions(mockDir);
    }

    /**
     * Defensive behavior: implementation throws NPE on null inputs by design.
     */
    @Test
    @DisplayName("implementation explicitly rejects nulls with NPE")
    void implementationRejectsNulls() {
        SmbFilenameFilter filter = (dir, name) -> {

    own the intellectual property, then you'll need to sign an [individual

  - If you work for a company that wants to allow you to contribute your work,
    then you'll need to sign a [corporate CLA][].

You generally only need to submit a CLA once, so if you've already submitted

    * Docker ile multi-stage yapı, böylece kodu derlemeniz, kaydetmeniz veya işlemeniz gerekmez.

     * In the case of Java tools, the map may also contain {@code --patch-module} options, which are
     * {@linkplain org.apache.maven.api.JavaPathType#patchModule(String) handled in a special way}.

     * <h4>Design note</h4>
     * All types of path are determined together because they are sometime mutually exclusive.
     * For example, an artifact of type {@value org.apache.maven.api.Type#JAR} can be placed

Das ist nicht zufällig so, das ganze Framework wurde um dieses Design herum aufgebaut.

Und es wurde in der Designphase gründlich getestet, vor der Implementierung, um sicherzustellen, dass es mit jedem Editor funktioniert.
