Constructor Detail

ICEBase64Encoder

public ICEBase64Encoder(OutputStream output)

Creates a new ICE specific Base64 encoder.

Parameters:

output - the underlying output stream receiving the Base64 encoded data

Method Detail

write

public void write(int b)
           throws IOException

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Specified by:

write in class OutputStream

Parameters:

b - the byte

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

write

public void write(byte[] data,
                  int off,
                  int len)
           throws IOException

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(data, off, len) is that some of the bytes in the array data are written to the output stream in order; element data[off] is the first byte written and data[off+len-1] is the last byte written by this operation.

If data 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 data, then an IndexOutOfBoundsException is thrown.

Overrides:

write in class OutputStream

Parameters:

data - the data

off - the start offset in the data

len - the number of bytes to write

Throws:

IOException - if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.

flush

public void flush()
           throws IOException

Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException - if an I/O error occurs

finishEncoding

public void finishEncoding()
                    throws IOException

Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

The close method of OutputStream does nothing.

Throws:

IOException - if an I/O error occurs

close

public void close()
           throws IOException

Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class OutputStream

Throws:

IOException - if an I/O error occurs
