* Inheritance Assembly

  Inheritance Assembly consists in filling current model empty fields with values taken from parent model.
  It is done in <<<InheritanceAssembler>>> ({{{./apidocs/org/apache/maven/model/inheritance/InheritanceAssembler.html}javadoc}}),
  with its <<<DefaultInheritanceAssembler>>> implementation

そして呼び出すと:

```Python
print(user_dict)
```

以下のようなPythonの`dict`を得ることができます:

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': '******@****.***',
    'full_name': None,
}
```

#### `dict`の展開

`user_dict`のような`dict`を受け取り、それを`**user_dict`を持つ関数（またはクラス）に渡すと、Pythonはそれを「展開」します。これは`user_dict`のキーと値を直接キー・バリューの引数として渡します。

そこで上述の`user_dict`の続きを以下のように書くと:

```Python

02E5..02E9    ; valid                  ;      ; NV8    # 1.1  MODIFIER LETTER EXTRA-HIGH TONE BAR..MODIFIER LETTER EXTRA-LOW TONE BAR
02EA..02EB    ; valid                  ;      ; NV8    # 3.0  MODIFIER LETTER YIN DEPARTING TONE MARK..MODIFIER LETTER YANG DEPARTING TONE MARK
02EC          ; valid                                  # 3.0  MODIFIER LETTER VOICING

     */
    public boolean available() {
        final String ssoType = getSsoType();
        if (logger.isDebugEnabled()) {
            logger.debug("sso.type: {}", ssoType);
        }
        return !Constants.NONE.equals(ssoType);
    }

    /**
     * Attempts to obtain login credentials using the configured SSO authenticator.
     *
     * @return The login credential from SSO authentication, or null if SSO is not available

 but is ready to use other logging implementations: SLF4J is responsible for loading the implementation, referred to as
 {{{http://www.slf4j.org/manual.html#swapping}"SLF4J bindings"}}.

 Logging configuration loading is actually done by logging implementation, without any Maven extensions to support merging
 Maven installation configuration with per-user configuration for example:
