Writes to the output stream all the bytes in array b.

Specified by:

write in interface JFWriter

Parameters:

b - the data.

Throws:

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

write

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

Writes len bytes from array b, in order, to the output stream.

Specified by:

write in interface JFWriter

Parameters:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

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

writeBoolean

public void writeBoolean(boolean v)
                  throws java.io.IOException

Writes a boolean value to this output stream. The byte written by this method may be read by the readBoolean method in JFReader.

Specified by:

writeBoolean in interface JFWriter

Parameters:

v - the boolean to be written.

Throws:

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

writeByte

public void writeByte(int v)
               throws java.io.IOException

Writes to the output stream the eight low- order bits of the argument v. The 24 high-order bits of v are ignored.

Specified by:

writeByte in interface JFWriter

Parameters:

v - the byte value to be written.

Throws:

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

writeShort

public void writeShort(int v)
                throws java.io.IOException

Specified by:

writeShort in interface JFWriter

Parameters:

v - the short value to be written.

Throws:

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