public static int encode(byte[] binaryData, int binaryOffset, int length, byte[] encodedData, int encodedOffset)
binaryData
- Binary data to be encoded.binaryOffset
- Offset into binaryData
where to
the data to be encoded begins.length
- Length of data to encode.encodedData
- Buffer receiving base64 encoded data.encodedOffset
- Offset into encodedData
where the
store base64 encoded data.
public static int decode(byte[] encodedData, int encodedOffset, int length, byte[] binaryData, int binaryOffset)
encodedData
- Base64 encoded data.encodedOffset
- Offset into encodedData
where the
base64 encoded data starts.length
- Length of encoded data.binaryData
- Decoded (binary) data.binaryOffset
- Offset into binaryData
where to
store the decoded binary data.
