class:XMLStreamWriter [NONE]

 
public interface XMLStreamWriter
The XMLStreamWriter interface specifies how to write XML. The XMLStreamWriter does not perform well formedness checking on its input. However the writeCharacters method is required to escape &, < and > For attribute values the writeAttribute method will escape the above characters plus " to ensure that all character content and attribute values are well formed. Each NAMESPACE and ATTRIBUTE must be individually written.

Notes:
  • [1] if namespaceURI == default Namespace URI, then no prefix is written
  • [2] if prefix == "" || null && namespaceURI == "", then no prefix or Namespace declaration is generated or written
  • [3] if prefix == "" || null, then a prefix is randomly generated
  • [4] if prefix == "" || null, then it is treated as the default Namespace and no prefix is generated or written, an xmlns declaration is generated and written if the namespaceURI is unbound
  • [5] if prefix == "" || null, then it is treated as an invalid attempt to define the default Namespace and an XMLStreamException is thrown

    method:setPrefix(java.lang.String,java.lang.String) [NONE]

    setPrefix

    void setPrefix?(String prefix, String uri) throws XMLStreamException
    Sets the prefix the uri is bound to. This prefix is bound in the scope of the current START_ELEMENT / END_ELEMENT pair. If this method is called before a START_ELEMENT has been written the prefix is bound in the root scope.
    Parameters:
    prefix - the prefix to bind to the uri, may not be null
    uri - the uri to bind to the prefix, may be null
    Throws:
    XMLStreamException

    method:setDefaultNamespace(java.lang.String) [NONE]

    setDefaultNamespace

    void setDefaultNamespace?(String uri) throws XMLStreamException
    Binds a URI to the default namespace This URI is bound in the scope of the current START_ELEMENT / END_ELEMENT pair. If this method is called before a START_ELEMENT has been written the uri is bound in the root scope.
    Parameters:
    uri - the uri to bind to the default namespace, may be null
    Throws:
    XMLStreamException

    method:setNamespaceContext(javax.xml.namespace.NamespaceContext) [NONE]

    setNamespaceContext

    void setNamespaceContext?(NamespaceContext context) throws XMLStreamException
    Sets the current namespace context for prefix and uri bindings. This context becomes the root namespace context for writing and will replace the current root namespace context. Subsequent calls to setPrefix and setDefaultNamespace will bind namespaces using the context passed to the method as the root context for resolving namespaces. This method may only be called once at the start of the document. It does not cause the namespaces to be declared. If a namespace URI to prefix mapping is found in the namespace context it is treated as declared and the prefix may be used by the StreamWriter.
    Parameters:
    context - the namespace context to use for this writer, may not be null
    Throws:
    XMLStreamException

    method:getNamespaceContext() [NONE]

    getNamespaceContext

    Returns the current namespace context.
    Returns:
    the current NamespaceContext

    Object getProperty?(String name) throws IllegalArgumentException
    Get the value of a feature/property from the underlying implementation
    Parameters:
    name - The name of the property, may not be null
    Returns:
    The value of the property
    Throws:
    IllegalArgumentException - if the property is not supported
    NullPointerException - if the name is null
