Class UnicodeString

java.lang.Object

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

All Implemented Interfaces:

java.lang.Comparable<UnicodeString>

public class UnicodeString
extends java.lang.Object
implements java.lang.Comparable<UnicodeString>

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<UnicodeString.FormatRun> 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(UnicodeString str)

Specified by:

compareTo in interface java.lang.Comparable<UnicodeString>

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object
