question: public void encode ( OutputStream out ) throws IOException { DerOutputStream tmp = new DerOutputStream ( ) ; if ( this . extensionValue == null ) { this . extensionId = PKIXExtensions . IssuingDistributionPoint_Id ; this . critical = false ; encodeThis ( ) ; } super . encode ( tmp ) ; out . write ( tmp . toByteArray ( ) ) ; }
target:  Encodes the issuing distribution point extension and writes it to the DerOutputStream.
