Class DOMWriterImpl

java.lang.Object
  org.codehaus.stax2.ri.dom.DOMWrappingWriter
      com.fasterxml.aalto.dom.DOMWriterImpl

All Implemented Interfaces:

XMLStreamWriter, org.codehaus.stax2.typed.TypedXMLStreamWriter, org.codehaus.stax2.validation.Validatable, org.codehaus.stax2.XMLStreamWriter2

public final class DOMWriterImpl
extends org.codehaus.stax2.ri.dom.DOMWrappingWriter

This is an adapter class that allows building a DOM tree using XMLStreamWriter interface.

Note that the implementation is only to be used for use with javax.xml.transform.dom.DOMResult.

Some notes regarding missing/incomplete functionality:

• Namespace-repairing mode not implemented
• Validation functionality not implemented

Field Detail

_config

protected final WriterConfig _config

_currElem

protected DOMOutputElement _currElem

This element is the current context element, under which all other nodes are added, until matching end element is output. Null outside of the main element tree.

Note: explicit empty element (written using writeEmptyElement) will never become current element.

_openElement

protected DOMOutputElement _openElement

This element is non-null right after a call to either writeStartElement and writeEmptyElement, and can be used to add attributes and namespace declarations.

Note: while this is often the same as _currElem, it's not always. Specifically, an empty element (written explicitly using writeEmptyElement) will become open element but NOT current element. Conversely, regular elements will remain current element when non elements are written (text, comments, PI), but not the open element.

_autoNsSeq

protected int[] _autoNsSeq

for NsRepairing mode

_suggestedDefNs

protected String _suggestedDefNs

_automaticNsPrefix

protected String _automaticNsPrefix
