question: private void initContents ( Composite main ) { if ( null != initialName ) { nameBox . setText ( initialName ) ; } if ( null != initialMeasurement ) { measurementBox . setText ( initialMeasurement ) ; } if ( null != initialField ) { fieldBox . setText ( initialField ) ; } if ( null != initialTags ) { for ( Entry < String , String > tag : initialTags . entrySet ( ) ) { TagKeyValueUIComponent tagComponent = new TagKeyValueUIComponent ( main , tag . getKey ( ) , tag . getValue ( ) ) ; tagComponents . add ( tagComponent ) ; } } }
