Method Detail

writeBigUTF

public static int writeBigUTF(java.lang.String str,
                              java.io.DataOutput out)
                       throws java.io.IOException

Writes a string to the specified DataOutput using Java modified UTF-8 encoding in a machine-independent manner.

• The first four bytes written hold the length of the string itself (the number of tokens in it).
• The next four bytes written hold the number of bytes that the UTF encoding consists of (this is greater than or equal to the string length)
• And finally, the bytes of the UTF encoding themselves are written.

Parameters:

str - a string to be written.

out - destination to write to

Returns:

The number of bytes written out.

Throws:

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