Examples of java.io.DataOutputStream.writeChars()

java.io.DataOutputStream.writeChars()
Writes the specified 16-bit characters contained in str to the OutputStream. Only the lower 2 bytes of each character are written with the higher of the 2 bytes written first. This represents the Unicode value of each character in str. @param str the String whose characters are to be written. @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readChar()

        dos.writeInt(stringTotalLength);


            //write the data in the stringheap, if there is any
            if (stringTotalLength > 0) {
                if (cas.getStringHeap().charHeapPos > 0) {
                    dos.writeChars( String.valueOf(cas.getStringHeap().stringHeap, 0, cas.getStringHeap().charHeapPos) );
                }
                else {
                    // no stringheap data
                    //if there is data in the string lists, write a leading 0
                    if ( stringListLength > 0 ) {
