public PDThread() 
{
        thread = new COSDictionary();
        thread.setName( "Type", "Thread" );
}

Default constructor.

 public PDThread(COSDictionary t) 
{
        thread = t;
}

Constructor that is used for a preexisting dictionary.

Parameters:

t - The underlying dictionary.

 public COSBase getCOSObject() 
{
        return thread;
}

Convert this standard java object to a COS object.

 public COSDictionary getDictionary() 
{
        return thread;
}

This will get the underlying dictionary that this object wraps.

 public PDThreadBead getFirstBead() 
{
        PDThreadBead retval = null;
        COSDictionary bead = (COSDictionary)thread.getDictionaryObject( "F" );
        if( bead != null )
        {
            retval = new PDThreadBead( bead );
        }
        return retval;
}

Get the first bead in the thread, or null if it has not been set yet. This is a required field for this object.

 public PDDocumentInformation getThreadInfo() 
{
        PDDocumentInformation retval = null;
        COSDictionary info = (COSDictionary)thread.getDictionaryObject( "I" );
        if( info != null )
        {
            retval = new PDDocumentInformation( info );
        }
        return retval;
}

Get info about the thread, or null if there is nothing.

 public  void setFirstBead(PDThreadBead bead) 
{
        if( bead != null )
        {
            bead.setThread( this );
        }
        thread.setItem( "F", bead );
}

This will set the first bead in the thread. When this is set it will also set the thread property of the bead object.

 public  void setThreadInfo(PDDocumentInformation info) 
{
        thread.setItem( "I", info );
}

Set the thread info, can be null.
