question: public static String create ( mxICell cell ) { String result = "" ; if ( cell != null ) { mxICell parent = cell . getParent ( ) ; while ( parent != null ) { int index = parent . getIndex ( cell ) ; result = index + mxCellPath . PATH_SEPARATOR + result ; cell = parent ; parent = cell . getParent ( ) ; } } return ( result . length ( ) > 1 ) ? result . substring ( 0 , result . length ( ) - 1 ) : "" ; }
target:  Creates the cell path for the given cell. The cell path is a concatenation of the indices of all cells on the (finite) path to the root, eg. "0.0.0.1".
