public class Digester
extends org.xml.sax.ext.DefaultHandler2
A Digester processes an XML input stream by matching a
series of element nesting patterns to execute Rules that have been added
prior to the start of parsing. This package was inspired by the
XmlMapper
class that was part of Tomcat 3.0 and 3.1,
but is organized somewhat differently.
See the Digester Developer Guide for more information.
IMPLEMENTATION NOTE - A single Digester instance may
only be used within the context of a single thread at a time, and a call
to parse()
must be completed before another can be initiated
even from the same thread.
IMPLEMENTATION NOTE - A bug in Xerces 2.0.2 prevents the support of XML schema. You need Xerces 2.1/2.3 and up to make this class working with XML schema

Digester
contains an internal EntityResolver
implementation. This maps PUBLICID
's to URLs
(from which the resource will be loaded). A common use case for this
method is to register local URLs (possibly computed at runtime by a
classloader) for DTDs. This allows the performance advantage of using
a local version without having to ensure every SYSTEM
URI on every processed xml document is local. This implementation provides
only basic functionality. If more sophisticated features are required,
using setEntityResolver(org.xml.sax.EntityResolver)
to set a custom resolver is recommended.
Note: This method will have no effect when a custom
EntityResolver
has been set. (Setting a custom
EntityResolver
overrides the internal implementation.)

public void clear()
Calling this method might allow another document of the same type to be correctly parsed. However this method was not intended for this purpose. In general, a separate Digester object should be created for each document to be parsed.

public java.lang.Object peekParams()
Return the top object on the parameters stack without removing it. If there are
no objects on the stack, return null
.
The parameters stack is used to store CallMethodRule
parameters.

Pop the top object off of the parameters stack, and return it. If there are
no objects on the stack, return null
.
The parameters stack is used to store CallMethodRule
parameters.

public void pushParams(java.lang.Object object)
Push a new object onto the top of the parameters stack.
The parameters stack is used to store CallMethodRule
parameters.
