Class TextPieceTable

java.lang.Object

org.apache.poi.hwpf.model.TextPieceTable

All Implemented Interfaces:

CharIndexTranslator

public final class TextPieceTable
extends java.lang.Object
implements CharIndexTranslator

The piece table for matching up character positions to bits of text. This mostly works in bytes, but the TextPieces themselves work in characters. This does the icky convertion.

public java.util.List getTextPieces()

isUnicodeAtCharOffset

public boolean isUnicodeAtCharOffset(int cp)

Is the text at the given Character offset unicode, or plain old ascii? In a very evil fashion, you have to actually know this to make sense of character and paragraph properties :(

Parameters:

cp - The character offset to check about

isUnicodeAtByteOffset

public boolean isUnicodeAtByteOffset(int bytePos)

Description copied from interface: CharIndexTranslator

Is the text at the given byte offset unicode, or plain old ascii? In a very evil fashion, you have to actually know this to make sense of character and paragraph properties :(

Specified by:

isUnicodeAtByteOffset in interface CharIndexTranslator

Parameters:

bytePos - The character offset to check about

Returns:

true if the text at the given byte offset is unicode

writeTo

               throws java.io.IOException

Throws:

java.io.IOException

adjustForInsert

public int adjustForInsert(int listIndex,
                  int length)

Adjust all the text piece after inserting some text into one of them

Parameters:

listIndex - The TextPiece that had characters inserted into

length - The number of characters inserted

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

getCharIndex

public int getCharIndex(int bytePos)

Description copied from interface: CharIndexTranslator

Calculates the char index of the given byte index.

Specified by:

getCharIndex in interface CharIndexTranslator

Parameters:

bytePos - The character offset to check

Returns:

the char index
