Class Base64OutputStreamWriter

java.lang.Object
  java.io.OutputStream
      com.sun.faces.io.Base64OutputStreamWriter

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class Base64OutputStreamWriter
extends java.io.OutputStream

Provides a mechanism to accept and Base64 encode bytes into chars which will be flushed to the provided writer as the internal buffer fills.

Constructor Summary

Base64OutputStreamWriter(int size, java.io.Writer writer)
Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.

Method Summary

void	close() Closing Base64OutputStreamWriter does nothing.
void	finish() Encodes the remaining bytes and flushes the char[] to the wrapped Writer.
int	getTotalCharsWritten()
void	write(byte[] b) Calls through to write(byte[], int, int)/
void	write(byte[] b, int off, int len) Writes len bytes from the specified byte array starting at offset off to this byte array output stream.
void	write(int b) Writes the specified byte to this byte array output stream.

Constructor Detail

Base64OutputStreamWriter

public Base64OutputStreamWriter(int size,
                                java.io.Writer writer)

Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.

Parameters:

size - the initial size.

writer - the writer we'll flush to once we reach our capacity

Throws:

java.lang.IllegalArgumentException - if size is negative.

Method Detail

write

public void write(int b)
           throws java.io.IOException

Writes the specified byte to this byte array output stream.

Specified by:

write in class java.io.OutputStream

Parameters:

b - the byte to be written.

Throws:

java.io.IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Writes len bytes from the specified byte array starting at offset off to this byte array output stream.

Overrides:

write in class java.io.OutputStream

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

Throws:

java.io.IOException

write

public void write(byte[] b)
           throws java.io.IOException

Calls through to write(byte[], int, int)/

Overrides:

write in class java.io.OutputStream

Parameters:

b - the bytes to write

Throws:

java.io.IOException - if an error occurs

close

public void close()
           throws java.io.IOException

Closing Base64OutputStreamWriter does nothing.

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException

finish

public void finish()
            throws java.io.IOException

Encodes the remaining bytes and flushes the char[] to the wrapped Writer.

Throws:

java.io.IOException

getTotalCharsWritten

public int getTotalCharsWritten()

Returns:

the total number of characters written
