Example 1 with FormatRun

use of org.apache.poi.hssf.record.common.UnicodeString.FormatRun in project poi by apache.

the class TestUnicodeString method formatRun.

@Test
public void formatRun() throws Exception {
    FormatRun fr = new FormatRun((short) 4, (short) 0x15c);
    assertEquals(4, fr.getCharacterPos());
    assertEquals(0x15c, fr.getFontIndex());
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    LittleEndianOutputStream out = new LittleEndianOutputStream(baos);
    fr.serialize(out);
    byte[] b = baos.toByteArray();
    assertEquals(4, b.length);
    assertEquals(4, b[0]);
    assertEquals(0, b[1]);
    assertEquals(0x5c, b[2]);
    assertEquals(0x01, b[3]);
    LittleEndianInputStream inp = new LittleEndianInputStream(new ByteArrayInputStream(b));
    fr = new FormatRun(inp);
    assertEquals(4, fr.getCharacterPos());
    assertEquals(0x15c, fr.getFontIndex());
}
