org.apache.myfaces.trinidad.util
Class Base64OutputStream

java.lang.Object
java.io.OutputStream
org.apache.myfaces.trinidad.util.Base64OutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable

public class Base64OutputStream

extends java.io.OutputStream

An OutputStream that encodes data in a base64 representation. It takes a Writer as its single argument to its constructor and all bytes written to the stream are correspondingly converted into Base64 and written out to the provided writer.

Constructor Summary

Base64OutputStream(java.io.Writer out)

Method Summary

void	close() Call this method to indicate end of data stream and to append any padding characters if necessary.
void	finish() Deprecated. use the close() method instead.
void	flush()
void	write(byte[] b, int off, int len) Writes len bytes from the specified byte array starting at offset off to this output stream.
void	write(int b) Takes a byte writes it out to the writer

public Base64OutputStream(java.io.Writer out)

Method Detail

write

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

Takes a byte writes it out to the writer

Specified by:

write in class java.io.OutputStream

Parameters:

b - a byte

Throws:

java.io.IOException

write

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

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation. The write method of OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation. If b is null, a NullPointerException is thrown. If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Overrides:

write in class java.io.OutputStream

Parameters:

b - the data

off - the start offset in the data

len - the number of bytes to read

Throws:

java.io.IOException

java.lang.NullPointerException

flush

public void flush()
           throws java.io.IOException

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.OutputStream

Throws:

java.io.IOException

finish

@Deprecated
public void finish()
            throws java.io.IOException

Deprecated. use the close() method instead.

Call this method to indicate end of data stream and to append any padding characters if necessary. This method should be called only if there will be no subsequent calls to a write method. Subsequent calls to the write method will result in incorrect encoding.

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Call this method to indicate end of data stream and to append any padding characters if necessary. This method should be called only if there will be no subsequent calls to a write method. Subsequent calls to the write method will result in incorrect encoding.

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException
