Class Base64EncoderIO

java.lang.Object
  com.bytecream.codec.Base64EncoderIO

public final class Base64EncoderIO

extends java.lang.Object

Provides a set of static methods to encode a stream with the Base64 algorithm.

The method encodeWithLineSeparator(...) uses the system line separator provided by System.getProperty("line.separator"). This line separator must be CRLF or a string of length 1.

For the best performance, use this library in server mode and disable assertions.

Method Summary

static void	encodeWithCRLF(java.io.InputStream _input, java.io.OutputStream _output) Encodes the data read from an input stream and write it on an output stream, inserting a CRLF every 76 characters.
static void	encodeWithLineSeparator(java.io.InputStream _input, java.io.OutputStream _output) Encodes the data read from an input stream and write it on an output stream, inserting a line separator every 76 characters.
static void	encodeWithLineSeparator(java.io.InputStream _input, java.io.OutputStream _output, boolean _end) Encodes the data read from an input stream and write it on an output stream, inserting a line separator every 76 characters.
static void	encodeWithoutSeparator(java.io.InputStream _input, java.io.OutputStream _output) Encodes the data read from an input stream and write it on an output stream.

Method Detail

encodeWithCRLF

public static final void encodeWithCRLF(java.io.InputStream _input,
                                        java.io.OutputStream _output)
                                 throws java.io.IOException

Encodes the data read from an input stream and write it on an output stream, inserting a CRLF every 76 characters. There is always a CRLF written at the end except if there is no input. You should use a buffered input stream.

Parameters:

_input - the input stream to read.

_output - the output stream to write on.

Throws:

java.io.IOException - if an I/O error occurs.

encodeWithLineSeparator

public static final void encodeWithLineSeparator(java.io.InputStream _input,
                                                 java.io.OutputStream _output)
                                          throws java.io.IOException

Encodes the data read from an input stream and write it on an output stream, inserting a line separator every 76 characters. There is always a line separator written at the end except if there is no input. You should use a buffered input stream.

Parameters:

_input - the input stream to read.

_output - the output stream to write on.

Throws:

java.io.IOException - if an I/O error occurs.

encodeWithLineSeparator

public static final void encodeWithLineSeparator(java.io.InputStream _input,
                                                 java.io.OutputStream _output,
                                                 boolean _end)
                                          throws java.io.IOException

Encodes the data read from an input stream and write it on an output stream, inserting a line separator every 76 characters. You should use a buffered input stream.

Parameters:

_input - the input stream to read.

_output - the output stream to write on.

_end - if true add a line separator to the final line, if false, add a line separator only if it has exactly 76 characters.

Throws:

java.io.IOException - if an I/O error occurs.

encodeWithoutSeparator

public static final void encodeWithoutSeparator(java.io.InputStream _input,
                                                java.io.OutputStream _output)
                                         throws java.io.IOException

Encodes the data read from an input stream and write it on an output stream. No separator is inserted. You should use a buffered input stream.

Parameters:

_input - the input stream to read.

_output - the output stream to write on.

Throws:

java.io.IOException - if an I/O error occurs.
