Method Detail

engineInit

protected abstract void engineInit(AlgorithmParameterSpec paramSpec)
                            throws InvalidParameterSpecException

Initializes this parameters object using the parameters specified in paramSpec.

Parameters:

paramSpec - the parameter specification.

InvalidParameterSpecException

engineInit

protected abstract void engineInit(byte[] params)
                            throws IOException

Imports the specified parameters and decodes them according to the primary decoding format for parameters. The primary decoding format for parameters is ASN.1, if an ASN.1 specification for this type of parameters exists.

Parameters:

params - the encoded parameters.

IOException

engineInit

protected abstract void engineInit(byte[] params,
                                   String format)
                            throws IOException

Imports the parameters from params and decodes them according to the specified decoding format. If format is null, the primary decoding format for parameters is used. The primary decoding format is ASN.1, if an ASN.1 specification for these parameters exists.

Parameters:

params - the encoded parameters.

format - the name of the decoding format.

IOException

engineGetParameterSpec

protected abstract AlgorithmParameterSpec engineGetParameterSpec(Class paramSpec)
                                                          throws InvalidParameterSpecException

Returns a (transparent) specification of this parameters object. paramSpec identifies the specification class in which the parameters should be returned. It could, for example, be DSAParameterSpec.class, to indicate that the parameters should be returned in an instance of the DSAParameterSpec class.

Parameters:

paramSpec - the the specification class in which the parameters should be returned.

Returns:

the parameter specification.

InvalidParameterSpecException

engineGetEncoded

protected abstract byte[] engineGetEncoded()
                                    throws IOException

Returns the parameters in their primary encoding format. The primary encoding format for parameters is ASN.1, if an ASN.1 specification for this type of parameters exists.

Returns:

the parameters encoded using the specified encoding scheme.

IOException

engineGetEncoded

protected abstract byte[] engineGetEncoded(String format)
                                    throws IOException

Returns the parameters encoded in the specified format. If format is null, the primary encoding format for parameters is used. The primary encoding format is ASN.1, if an ASN.1 specification for these parameters exists.

Parameters:

format - the name of the encoding format.

Returns:

the parameters encoded using the specified encoding scheme.

IOException

engineToString

protected abstract String engineToString()

Returns a formatted string describing the parameters.

Returns:

a formatted string describing the parameters.
