question: public void addKeyValueComment ( String keyName , String value ) { int keyIndex ; if ( ( keyIndex = findKeyCommentIndex ( keyName ) ) < 0 ) { keyValComments . add ( "! " + keyName + ": " + value + "\n" ) ; return ; } log . warn ( "Key " + keyName + " already exists in key/value set.  Overriding previous value!" ) ; keyValComments . set ( keyIndex , "! " + keyName + ": " + value + "\n" ) ; }
target:  Updates the internal key/value storage to reflect the parameters. If the key already exists, its value is updated based on the parameter. If the key does not exist, a new key/value pair comment is added to the key/value storage list.
