                     throws javax.xml.stream.XMLStreamException

Write text to the output

Specified by:

getPrefix

public String getPrefix(String uri)
                 throws javax.xml.stream.XMLStreamException

Gets the prefix the uri is bound to

Specified by:

getPrefix in interface javax.xml.stream.XMLStreamWriter

Returns:

the prefix or null

Throws:

javax.xml.stream.XMLStreamException

setPrefix

public void setPrefix(String prefix,
             String uri)
               throws javax.xml.stream.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.

Specified by:

setPrefix in interface javax.xml.stream.XMLStreamWriter

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:

javax.xml.stream.XMLStreamException

setDefaultNamespace

public void setDefaultNamespace(String uri)
                         throws javax.xml.stream.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.

Specified by:

setDefaultNamespace in interface javax.xml.stream.XMLStreamWriter

Parameters:

uri - the uri to bind to the default namespace, may be null

Throws:

javax.xml.stream.XMLStreamException

setNamespaceContext

public void setNamespaceContext(NamespaceContext context)
                         throws javax.xml.stream.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.

Specified by:

setNamespaceContext in interface javax.xml.stream.XMLStreamWriter

Parameters:

context - the namespace context to use for this writer, may not be null

Throws:

javax.xml.stream.XMLStreamException

getNamespaceContext

public NamespaceContext getNamespaceContext()

Returns the current namespace context.

Specified by:

getNamespaceContext in interface javax.xml.stream.XMLStreamWriter

Returns:

the current NamespaceContext

                   throws IllegalArgumentException

Get the value of a feature/property from the underlying implementation

Specified by:

getProperty in interface javax.xml.stream.XMLStreamWriter

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
