question: protected boolean loadField ( DDFRecord record , String tagName , int fieldIndex ) { if ( fields . get ( tagName ) == null ) { DDFField ddf = record . findField ( tagName , fieldIndex ) ; if ( ddf != null ) { fields . put ( tagName , ddf ) ; ddf . toString ( ) ; return true ; } } return false ; }
target:  If a field has not been loaded, load it from the DDFRecord if it exists and add it to the master field hashtable.
