Class XmlFactory

java.lang.Object

com.fasterxml.jackson.core.JsonFactory

com.fasterxml.jackson.dataformat.xml.XmlFactory

All Implemented Interfaces:

com.fasterxml.jackson.core.Versioned, Serializable

public class XmlFactory
extends com.fasterxml.jackson.core.JsonFactory

Factory used for constructing FromXmlParser and ToXmlGenerator instances.

Implements JsonFactory since interface for constructing XML backed parsers and generators is quite similar to dealing with JSON.

Constructor Detail

XmlFactory

public XmlFactory()

Default constructor used to create factory instances. Creation of a factory instance is a light-weight operation, but it is still a good idea to reuse limited number of factory instances (and quite often just a single instance): factories are used as context for storing some reused processing objects (such as symbol tables parsers use) and this reuse only works within context of a single factory instance.

Method that tries to figure out if content seems to be in some kind of XML format. Note that implementation here is not nearly as robust as what underlying Stax parser will do; the idea is to first support common encodings, then expand as needed (for example, it is not all that hard to support UTF-16; but it is some work and not needed quite yet)

Throws:

IOException
