Class SignatureCodecFactory

public class SignatureCodecFactory
extends Object
A Factory class to instantiate Signature codecs.

Method Summary

static ISignatureCodec
getInstance(String name)
Returns the appropriate codec given a composed signature algorithm and an encoding format.
static ISignatureCodec
getInstance(String name, int formatID)
Returns an instance of a signature codec given the canonical name of the signature algorithm, and the identifier of the format to use when encoding/decoding signatures generated by that algorithm.
static ISignatureCodec
getInstance(String name, String format)
Returns an instance of a signature codec given the canonical name of the signature algorithm, and that of the encoding format.
static Set<E>
getNames()
Returns a Set of supported signature codec names.

Method Details

getInstance

public static ISignatureCodec getInstance(String name)
Returns the appropriate codec given a composed signature algorithm and an encoding format. A composed name is formed by the concatenation of the canonical signature algorithm name, the forward slash character / and the canonical name of the encoding format.

When the encoding format name is missing, the Raw encoding format is assumed. When this is the case the trailing forward slash is discarded from the name.

Parameters:
name - the case-insensitive, possibly composed, signature codec name.
Returns:
an instance of the signaturecodec, or null if none found.

getInstance

public static ISignatureCodec getInstance(String name,
                                          int formatID)
Returns an instance of a signature codec given the canonical name of the signature algorithm, and the identifier of the format to use when encoding/decoding signatures generated by that algorithm.
Parameters:
name - the case-insensitive signature algorithm name.
formatID - the identifier of the format to use when encoding / decoding signatures generated by the designated algorithm.
Returns:
an instance of the signature codec, or null if none found.

getInstance

public static ISignatureCodec getInstance(String name,
                                          String format)
Returns an instance of a signature codec given the canonical name of the signature algorithm, and that of the encoding format.
Parameters:
name - the case-insensitive signature algorithm name.
format - the name of the format to use when encodigng/decoding signatures generated by the named algorithm.
Returns:
an instance of the signature codec, or null if none found.

getNames

public static final Set<E> getNames()
Returns a Set of supported signature codec names.
Returns:
a Set of the names of supported signature codec (Strings).
