/*---------------------------
|
||
|
|
The AdminDispatcher trait provides functions to pass
|
||
|
|
manipulation requests on to child nodes.
|
||
|
|
|
||
|
|
Classes using this trait must be inherited from Parentum!
|
||
|
|
|
||
|
|
The "path" is definded a an enumeration of id numbers along
|
||
|
|
the structural path, seperated by ";",
|
||
|
|
|
||
|
|
eg.: 1;2;5;18
|
||
|
|
This will try to return the node with the id "18" that is a child
|
||
|
|
of "5", which is child of "2", which is child of "1". "1" in this
|
||
|
|
case is the first instance that calls getElementByPath() without
|
||
|
|
arguments.
