* Lumiera source code always was copyrighted by individual contributors * there is no entity "Lumiera.org" which holds any copyrights * Lumiera source code is provided under the GPL Version 2+ == Explanations == Lumiera as a whole is distributed under Copyleft, GNU General Public License Version 2 or above. For this to become legally effective, the ''File COPYING in the root directory is sufficient.'' The licensing header in each file is not strictly necessary, yet considered good practice; attaching a licence notice increases the likeliness that this information is retained in case someone extracts individual code files. However, it is not by the presence of some text, that legally binding licensing terms become effective; rather the fact matters that a given piece of code was provably copyrighted and published under a license. Even reformatting the code, renaming some variables or deleting parts of the code will not alter this legal situation, but rather creates a derivative work, which is likewise covered by the GPL! The most relevant information in the file header is the notice regarding the time of the first individual copyright claim. By virtue of this initial copyright, the first author is entitled to choose the terms of licensing. All further modifications are permitted and covered by the License. The specific wording or format of the copyright header is not legally relevant, as long as the intention to publish under the GPL remains clear. The extended wording was based on a recommendation by the FSF. It can be shortened, because the full terms of the license are provided alongside the distribution, in the file COPYING.

|

* @test verify the simple standard usage pattern, where command arguments
|
||
* for binding are passed via UI-Bus message with GenNode elements.
|
||
* This is a simplified demonstration, but covers some tricky aspects.
|
||
* - commands may define arguments of arbitrary type, and at runtime
|
||
* these are initialised from the set of standard types allowed
|
||
* within GenNode elements. Here the Duration is initialised from
|
||
* a TimeSpan object
|
||
* - we support immutable argument types, which means the command binding
|
||
* machinery works without (re)assignment, only copy construction of
|
||
* argument holders into an inline buffer.
|
||
* - likewise we support to use an immutable type as captured state
|
||
* memento, which is demonstrated by capturing a Time value
