    • Method Detail

      • getTag

        public Tag getTag()
        Description copied from interface: ASN1Value
        Returns the base tag for this type, not counting any tags that may be imposed on it by its context.
        Specified by:
        getTag in interface ASN1Value
        Returns:
        Base tag.
      • getParameters

        public ASN1Value getParameters()
        If this instance was constructed, returns the parameter passed in to the constructor. If this instance was decoded from a template, returns an ANY that was read from the BER stream. In either case, it will return null if no parameters were supplied.
      • encode

        public void encode​(java.io.OutputStream ostream)
                    throws java.io.IOException
        Description copied from interface: ASN1Value
        Write this value's DER encoding to an output stream using its own base tag.
        Specified by:
        encode in interface ASN1Value
        Parameters:
        ostream - Output stream.
        Throws:
        java.io.IOException - If an error occurred.
      • encode

        public void encode​(Tag implicit,
                           java.io.OutputStream ostream)
                    throws java.io.IOException
        Description copied from interface: ASN1Value
        Write this value's DER encoding to an output stream using an implicit tag.
        Specified by:
        encode in interface ASN1Value
        Parameters:
        implicit - Implicit tag.
        ostream - Output stream.
        Throws:
        java.io.IOException - If an error occurred.
