question: private void createViewToModel ( int rowCount ) { int recreateFrom = 0 ; if ( viewToModel != null ) { recreateFrom = Math . min ( rowCount , viewToModel . length ) ; if ( viewToModel . length != rowCount ) { Row [ ] oldViewToModel = viewToModel ; viewToModel = new Row [ rowCount ] ; System . arraycopy ( oldViewToModel , 0 , viewToModel , 0 , recreateFrom ) ; } } else { viewToModel = new Row [ rowCount ] ; } int i ; for ( i = 0 ; i < recreateFrom ; i ++ ) { viewToModel [ i ] . modelIndex = i ; } for ( i = recreateFrom ; i < rowCount ; i ++ ) { viewToModel [ i ] = new Row ( this , i ) ; } }
target:  Resets the viewToModel array to be of size rowCount.
