Class PTreeReader

java.lang.Object
  com.saxonica.ptree.PTreeReader

public class PTreeReader
extends Object

This class loads a TinyTree held as a serialized binary file on disk, in a proprietary format designed for speed of loading back into a new TinyTree.

The format stored on disk is not dependent on the NamePool. Although it still uses name codes, it also contains a mapping of namecodes to the actual QNames.

The base URIs of nodes are not retained. Line numbers (if they were present in the original tree) are not retained.

setTextMangler

public void setTextMangler(TextMangler mangler)

Set a callback object that will be used to unmangle the content of attribute nodes and text nodes

Parameters:

mangler - the object to perform the content mangling

readTree

public DocumentInfo readTree(DataInputStream in,
                             String systemId,
                             Configuration config)
                      throws IOException,
                             XPathException

Read an input stream containing an XML document in PTree format, returning an in-memory representation of the document

Parameters:

in - the input stream holding the PTree document. The method will consume the stream; the caller is responsible for closing the stream after use.

systemId - the base URI to be used for the document associated with this input stream

config - the Saxon Configuration

Returns:

the root node of the constructed in-memory document

Throws:

IOException - if an error occurs reading the input stream

XPathException - if an error occurs building the in-memory document

readTree

public void readTree(DataInputStream in,
                     String systemId,
                     Configuration config,
                     Receiver out)
              throws IOException,
                     XPathException

Read an input stream containing an XML document in PTree format, passing the events associated with the document to a Saxon Receiver

Parameters:

in - the input stream holding the PTree document. The method will consume the stream; the caller is responsible for closing the stream after use.

systemId - the base URI to be used for the document associated with this input stream

config - the Saxon Configuration

out - the Receiver to receive the document events

Throws:

IOException - if an error occurs reading the input stream

XPathException - if an error occurs building the in-memory document

main

public static void main(String[] args)
                 throws Exception
