  • Method Details

    • getParameterType

      protected abstract Class<P> getParameterType()
      Get the type of parameters for this class.
      Returns:
      the type of parameters for this class (must not be null)

    • engineInit

      protected final void engineInit(AlgorithmParameterSpec paramSpec) throws InvalidParameterSpecException
      Implementation of the engineInit method.
      Specified by:
      engineInit in class AlgorithmParametersSpi
      Parameters:
      paramSpec - the parameter specification
      Throws:
      InvalidParameterSpecException - if an argument is invalid or encoding failed

    • engineInit

      protected final void engineInit(byte[] params) throws IOException
      Implementation of the engineInit method.
      Specified by:
      engineInit in class AlgorithmParametersSpi
      Parameters:
      params - the encoded parameter specification
      Throws:
      IOException - if decoding failed

    • engineInit

      protected final void engineInit(byte[] params, String format) throws IOException
      Implementation of the engineInit method.
      Specified by:
      engineInit in class AlgorithmParametersSpi
      Parameters:
      params - the encoded parameter specification
      format - the format (must be ASN.1)
      Throws:
      IOException - if decoding failed or the format is not equal to ASN.1

    • engineEncode

      protected abstract void engineEncode(ASN1Encoder encoder, P parameters) throws ASN1Exception, InvalidParameterSpecException
      Encode a parameter instance.
      Parameters:
      encoder - the encoder to use (not null)
      parameters - the parameter instance (not null)
      Throws:
      ASN1Exception - if there is an encoding problem (usually thrown directly by the ASN1Encoder)
      InvalidParameterSpecException - if some other encoding error occurred

    • engineDecode

      protected abstract P engineDecode(ASN1Decoder decoder) throws ASN1Exception, IOException
      Decode a parameter instance. Subclasses should ensure that all elements are consumed (including sequence terminators and so forth).
      Parameters:
      decoder - the decoder to use (not null)
      Returns:
      the parameter instance (must not be null)
      Throws:
      ASN1Exception - if there is a decoding problem (usually thrown directly by the ASN1Decoder)
      IOException - if some other decoding error occurred
