Method Detail

supports

public abstract boolean supports(String encoding)

For concrete decoders this method should return true if the given encoding is supported.

Parameters:

encoding - the encoding to check for.

Returns:

true if the encoding is supported by the decoder.

decode

public abstract byte[] decode(String data)

Decode the given data into the encoding that is supported by the encoder.

Parameters:

data - the data to decode.

Returns:

the decoded data.

forEncoding

public static ByteArrayDecoder forEncoding(String encoding)

Return an decoder for the given encoding (e.g. base58).

Parameters:

encoding - the encoding for which an decoder should be created.

Returns:

the decoder for the encoding or null if no decoder is available.
