The encoding that this decoder supports.
Creates a new base64 decoder with exactly the same state as this decoder.
A new decoder with identical state.
Estimates the number of bytes needed to decode the specified number of input bytes.
The input length.
The estimated output length.
Decodes the specified input into the output buffer.
The output buffer should be large enough to hold all decoded input. Use estimateOutputLength to estimate the required size.
The input buffer.
The starting index of the input buffer.
The length of the input range.
The output buffer.
The number of bytes written to the output buffer.
Resets the state of the decoder.
Incrementally decodes content encoded with the base64 encoding.
Base64 is often used in MIME to encode binary content such as images and other multimedia so that data remains intact over 7-bit transports such as SMTP.
