Method Detail

decode

void decode(@Nullable
            byte[] aEncodedBuffer,
            @Nonnegative
            int nOfs,
            @Nonnegative
            int nLen,
            @Nonnull @WillNotClose
            OutputStream aOS)

Decode a byte array.

Parameters:

aEncodedBuffer - The byte array to be decoded. May be null.

nOfs - Offset into the byte array to start from.

nLen - Number of bytes starting from offset to consider.

aOS - The output stream to write to. May not be null and is NOT closed afterwards!

Throws:

DecodeException - in case something goes wrong

getDecoded

@Nullable
 @ReturnsMutableCopy
default byte[] getDecoded(@Nullable
                                                           byte[] aEncodedBuffer,
                                                           @Nonnegative
                                                           int nOfs,
                                                           @Nonnegative
                                                           int nLen)

Decode a byte array.

Specified by:

getDecoded in interface IByteArrayDecoder

Parameters:

aEncodedBuffer - The byte array to be decoded. May be null.

nOfs - Offset into the byte array to start from.

nLen - Number of bytes starting from offset to consider.

Returns:

The decoded byte array or null if the parameter was null.

Throws:

DecodeException - in case something goes wrong
