                  throws IOException

unused

Specified by:

writeContent in interface RtfBasicElement

Specified by:

writeContent in class RtfElement

Parameters:

out - The OutputStream to write the content to

Throws:

IOException

writeDocument

public void writeDocument(OutputStream out)

Writes the document

Parameters:

out - The OutputStream to write the RTF document to.

open

public void open()

Opens the RtfDocument and initializes the data cache. If the data cache is set to CACHE_DISK, but the cache cannot be initialized then the memory cache is used.

add

public void add(RtfBasicElement element)

Adds an element to the rtf document

Parameters:

element - The element to add

getMapper

public RtfMapper getMapper()

Gets the RtfMapper object of this RtfDocument

Returns:

The RtfMapper

getRandomInt

public int getRandomInt()

Generates a random integer that is unique with respect to the document. Will not return a number between -1 and -5 because some values in that range are invalid.

Returns:

A random int

getDocumentHeader

public RtfDocumentHeader getDocumentHeader()

Gets the RtfDocumentHeader of this RtfDocument

Returns:

The RtfDocumentHeader of this RtfDocument

filterSpecialChar

public void filterSpecialChar(OutputStream out,

Writes the given string to the given OutputStream encoding the string characters.

Parameters:

out - destination OutputStream

str - string to write

useHex - if true hex encoding characters is preferred to unicode encoding if possible

softLineBreaks - if true return characters are written as soft line breaks

Throws:

IOException

subMatch

private static boolean subMatch(String str,

Returns true if m.length characters in str, starting at offset soff match the bytes in the given array m.

Parameters:

str - the string to search for a match

soff - the starting offset in str

m - the array to match

Returns:

true if there is match

setAutogenerateTOCEntries

Whether to automagically generate table of contents entries when adding Chapters or Sections.

Parameters:

autogenerate - Whether to automatically generate TOC entries

getAutogenerateTOCEntries

public boolean getAutogenerateTOCEntries()

Get whether to automatically generate table of contents entries

Gets the last RtfBasicElement that was directly added to the RtfDocument.

Returns:

The last RtfBasicElement that was directly added to the RtfDocument.

outputDebugLinebreak

public final void outputDebugLinebreak(OutputStream result)
                                throws IOException

Helper method outputs linebreak in document if debugging is turned on.
