## org.apache.poi.hssf.record.common
Class UnicodeString

    java.lang.Object
      org.apache.poi.hssf.record.common.UnicodeString

All Implemented Interfaces:
  java.lang.Comparable

Direct Known Subclasses:
  UnicodeString

    public class UnicodeString

extends java.lang.Object
implements java.lang.Comparable

Title: Unicode String

Description: Unicode String - just standard fields that are in several records. It is considered more desirable then repeating it in all of them.

This is often called a XLUnicodeRichExtendedString in MS documentation.

Constructor Detail

### UnicodeString

    public UnicodeString(java.lang.String str)

### UnicodeString

    public UnicodeString(RecordInputStream in)

  construct a unicode string record and fill its fields, ID is ignored

  Parameters:
    `in` - the RecordInputstream to read the record from

Method Detail

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `java.lang.Object`

### equals

    public boolean equals(java.lang.Object o)

  Our handling of equals is inconsistent with compareTo. The trouble is because we don't truely understand rich text fields yet it's difficult to make a sound comparison.

  Overrides:
    `equals` in class `java.lang.Object`
  Parameters:
    `o` - The object to compare.
  Returns:
    true if the object is actually equal.

### getCharCount

    public int getCharCount()

  get the number of characters in the string, as an un-wrapped int

  Returns:
    number of characters

### getCharCountShort

    public short getCharCountShort()

  get the number of characters in the string, wrapped as needed to fit within a short

  Returns:
    number of characters

### setCharCount

    public void setCharCount(short cc)

  set the number of characters in the string

  Parameters:
    `cc` - - number of characters

### getOptionFlags

    public byte getOptionFlags()

  get the option flags which among other things return if this is a 16-bit or 8 bit string

  Returns:
    optionflags bitmask

### setOptionFlags

    public void setOptionFlags(byte of)

  set the option flags which among other things return if this is a 16-bit or 8 bit string

  Parameters:
    `of` - optionflags bitmask

### getString

    public java.lang.String getString()

  Returns:
    the actual string this contains as a java String object

### setString

    public void setString(java.lang.String string)

  set the actual string this contains

  Parameters:
    `string` - the text

### getFormatRunCount

    public int getFormatRunCount()

### getFormatRun

    public UnicodeString.FormatRun getFormatRun(int index)

### addFormatRun

    public void addFormatRun(UnicodeString.FormatRun r)

  Adds a font run to the formatted string. If a font run exists at the current charcter location, then it is replaced with the font run to be added.

### formatIterator

    public java.util.Iterator formatIterator()

### removeFormatRun

    public void removeFormatRun(UnicodeString.FormatRun r)

### clearFormatting

    public void clearFormatting()

### getExtendedRst

    public UnicodeString.ExtRst getExtendedRst()

### swapFontUse

    public void swapFontUse(short oldFontIndex,
                            short newFontIndex)

  Swaps all use in the string of one font index for use of a different font index. Normally only called when fonts have been removed / re-ordered

### toString

    public java.lang.String toString()

  unlike the real records we return the same as "getString()" rather than debug info

  Overrides:
    `toString` in class `java.lang.Object`
  Returns:
    String value of the record
  See Also:
    `getDebugInfo()`

### getDebugInfo

    public java.lang.String getDebugInfo()

  return a character representation of the fields of this record

  Returns:
    String of output for biffviewer etc.

### serialize

    public void serialize(ContinuableRecordOutput out)

  Serialises out the String. There are special rules about where we can and can't split onto Continue records.

### compareTo

    public int compareTo(java.lang.Object istr)

  Specified by:
    `compareTo` in interface `java.lang.Comparable`

### clone

    public java.lang.Object clone()

  Overrides:
    `clone` in class `java.lang.Object`
