Class XmlSerializerDelegate

java.lang.Object
  extended by org.xmlpull.v1.wrapper.classic.XmlSerializerDelegate
All Implemented Interfaces:
XmlSerializer
Direct Known Subclasses:
StaticXmlSerializerWrapper

public class XmlSerializerDelegate
extends java.lang.Object
implements XmlSerializer

This is simple class that implements serializer interface by delegating all calls to actual serialzier implementation passed in constructor. Purpose of this class is to work as base class to allow extending interface by wrapping exsiting parser implementation and allowing ot add new methods.

XmlSerializerDelegate

public XmlSerializerDelegate(XmlSerializer serializer)
Method Detail

getName

public java.lang.String getName()
Description copied from interface: XmlSerializer
Returns the name of the current element as set by startTag(). It can only be null before first call to startTag() or when last endTag() is called to close first startTag().

Specified by:
getName in interface XmlSerializer
Returns:
namespace set by startTag() that is currently in scope

setPrefix

public void setPrefix(java.lang.String prefix,
                      java.lang.String namespace)
               throws java.io.IOException,
                      java.lang.IllegalArgumentException,
                      java.lang.IllegalStateException
Description copied from interface: XmlSerializer
Binds the given prefix to the given namespace. This call is valid for the next element including child elements. The prefix and namespace MUST be always declared even if prefix is not used in element (startTag() or attribute()) - for XML 1.0 it must result in declaring xmlns:prefix='namespace' (or xmlns:prefix="namespace" depending what character is used to quote attribute value).

NOTE: this method MUST be called directly before startTag() and if anything but startTag() or setPrefix() is called next there will be exception.

NOTE: prefixes "xml" and "xmlns" are already bound and can not be redefined see: Namespaces in XML Errata.

NOTE: to set default namespace use as prefix empty string.

Specified by:
setPrefix in interface XmlSerializer
Parameters:
prefix - must be not null (or IllegalArgumentException is thrown)
namespace - must be not null
