public class XfaTreeNode
extends FormTreeNode
implements OutputStreamResource

This is the root tree node for the different parts of the XFA resource; it's a child of the root in the FormTree. This resource can be one XDP stream (in which case this root will only have one child) or different streams with individual packets comprising the XML Data Package.

Constructor Details

XfaTreeNode

public XfaTreeNode(PdfObjectTreeNode xfa)

Creates the root node of the XFA tree. This will be a child of the FormTree root node.

Parameters:

xfa - the XFA node in the PdfTree (a child of the AcroForm node in the PDF catalog)

Method Details

writeTo

public void writeTo(OutputStream os)
             throws IOException

Writes (part of) the XFA resource to an OutputStream. If key is null, the complete resource is written; if key refers to an individual package, this package only is written to the OutputStream.

Specified by:

writeTo in interface OutputStreamResource

Parameters:

os - the OutputStream to which the XML is written.

Throws:

IOException - usual exception when there's a problem writing to an OutputStream

addPacket

public void addPacket(String key,
 PdfObjectTreeNode value)

Adds a child node to the XFA root. The child node either corresponds with the complete XDP stream (if the XFA root only has one child) or with individual packet.

Parameters:

key - the name of the packet

value - the corresponding stream node in the PdfTree
