Example 1 with ContinuableRecordOutput

use of org.apache.poi.hssf.record.cont.ContinuableRecordOutput in project poi by apache.

the class TestUnicodeString method confirmSize.

     * Note - a value of zero for <tt>amountUsedInCurrentRecord</tt> would only ever occur just
     * after a {@link ContinueRecord} had been started.  In the initial {@link SSTRecord} this 
     * value starts at 8 (for the first {@link UnicodeString} written).  In general, it can be
     * any value between 0 and {@link #MAX_DATA_SIZE}
