Method Summary

Modifier and Type	Method	Description
protected void	checkStartElement(String localName, String prefix)	Method that is called to ensure that we can start writing an element, both from structural point of view, and from syntactic (close previously open start element, if any).
protected void	closeStartElement(boolean emptyElem)	Method called to close an open start element, when another main-level element (not namespace declaration or attribute) is being output; except for end element which is handled differently.
abstract void	doSetPrefix(String prefix, String uri)
protected void	doWriteAttr(String localName, String nsURI, String prefix, char[] buf, int start, int len)
protected void	doWriteAttr(String localName, String nsURI, String prefix, String value)
protected void	doWriteDefaultNs(String nsURI)
protected void	doWriteEndTag(QName expName, boolean allowEmpty)
protected void	doWriteNamespace(String prefix, String nsURI)
protected void	doWriteStartTag(String localName)
protected void	doWriteStartTag(String prefix, String localName)
QName	getCurrentElementName()	Method that can be used to access name information of the innermost (top) element in the element stack.
NamespaceContext	getNamespaceContext()
String	getNamespaceURI(String prefix)	Method that can be called by the validator to resolve a namespace prefix of the currently active top-level element.
String	getPrefix(String uri)
protected String	getTopElementDesc()	Method needed for error message generation
abstract void	setDefaultNamespace(String uri)
void	setNamespaceContext(NamespaceContext ctxt)	Note: Root namespace context works best if automatic prefix creation ("namespace/prefix repairing" in StAX lingo) is enabled.
void	setPrefix(String prefix, String uri)
void	writeAttribute(String localName, String value)	It's assumed calling this method implies caller just wants to add an attribute that does not belong to any namespace; as such no namespace checking or prefix generation is needed.
abstract void	writeAttribute(String nsURI, String localName, String value)
abstract void	writeAttribute(String prefix, String nsURI, String localName, String value)
abstract void	writeDefaultNamespace(String nsURI)
void	writeEmptyElement(String localName)	Note: It is assumed caller just wants the element to belong to whatever is the current default namespace.
void	writeEmptyElement(String nsURI, String localName)
void	writeEmptyElement(String prefix, String localName, String nsURI)
void	writeEndElement()
void	writeEndElement(QName name)	Method called by XMLEventWriter implementation (instead of the version that takes no argument), so that we can verify it does match the start element, if necessary
void	writeFullEndElement()	Similar to writeEndElement(), but never allows implicit creation of empty elements.
abstract void	writeNamespace(String prefix, String nsURI)
void	writeStartElement(String localName)	This method is assumed to just use default namespace (if any), and no further checks should be done.
void	writeStartElement(String nsURI, String localName)
void	writeStartElement(String prefix, String localName, String nsURI)
abstract void	writeStartElement(StartElement elem)	Convenience method needed by XMLEventWriter implementation, to use when writing a start element, and possibly its attributes and namespace declarations.
protected abstract void	writeStartOrEmpty(String localName, String nsURI)
protected abstract void	writeStartOrEmpty(String prefix, String localName, String nsURI)
protected void	writeTypedAttribute(String prefix, String nsURI, String localName, AsciiValueEncoder enc)	Method that will write attribute with value that is known not to require additional escaping.
