Interface Encoder

All Known Implementing Classes:

Base32Encoder, Base64Encoder, HexEncoder

public interface Encoder

Encode and decode byte arrays (typically from binary to 7-bit ASCII encodings).

Method Summary

int	decode(byte[] data, int off, int length, java.io.OutputStream out)
int	decode(java.lang.String data, java.io.OutputStream out)
int	encode(byte[] data, int off, int length, java.io.OutputStream out)
int	getEncodedLength(int inputLength) Return the expected output length of the encoding.
int	getMaxDecodedLength(int inputLength) Return the maximum expected output length of a decoding.

Method Detail

getEncodedLength

public int getEncodedLength(int inputLength)

Return the expected output length of the encoding.

Parameters:

inputLength - the input length of the data.

Returns:

the output length of an encoding.

getMaxDecodedLength

public int getMaxDecodedLength(int inputLength)

Return the maximum expected output length of a decoding. If padding is present the value returned will be greater than the decoded data length.

Parameters:

inputLength - the input length of the encoded data.

Returns:

the upper bound of the output length of a decoding.
