|
* A class for generating unique IDs, in two possible ways.
|
|
*
|
|
* Almost every XMI element contains a UID. This class can generate both globally
|
|
* unique IDs, and deterministic unique IDs (ie. the IDs are the same every time the
|
|
* parser is run again). We need such deterministic IDs because of the PHP_UML test
|
|
* suite, which would report errors otherwise (because of different IDs !)
|
|
* You select which one by setting the boolean property $determinisic to true/false
