add

public void add(javax.xml.stream.events.XMLEvent e)
         throws javax.xml.stream.XMLStreamException
Description copied from interface: javax.xml.stream.XMLEventWriter
Add an event to the output stream Adding a START_ELEMENT will open a new namespace scope that will be closed when the corresponding END_ELEMENT is written.
Required and optional fields for events added to the writer
Event Type Required Fields Optional Fields Required Behavior
START_ELEMENT QName name namespaces , attributes A START_ELEMENT will be written by writing the name, namespaces, and attributes of the event in XML 1.0 valid syntax for START_ELEMENTs. The name is written by looking up the prefix for the namespace uri. The writer can be configured to respect prefixes of QNames. If the writer is respecting prefixes it must use the prefix set on the QName. The default behavior is to lookup the value for the prefix on the EventWriter's internal namespace context. Each attribute (if any) is written using the behavior specified in the attribute section of this table. Each namespace (if any) is written using the behavior specified in the namespace section of this table.
END_ELEMENT Qname name None A well formed END_ELEMENT tag is written. The name is written by looking up the prefix for the namespace uri. The writer can be configured to respect prefixes of QNames. If the writer is respecting prefixes it must use the prefix set on the QName. The default behavior is to lookup the value for the prefix on the EventWriter's internal namespace context. If the END_ELEMENT name does not match the START_ELEMENT name an XMLStreamException is thrown.
ATTRIBUTE QName name , String value QName type An attribute is written using the same algorithm to find the lexical form as used in START_ELEMENT. The default is to use double quotes to wrap attribute values and to escape any double quotes found in the value. The type value is ignored.
NAMESPACE String prefix, String namespaceURI, boolean isDefaultNamespaceDeclaration None A namespace declaration is written. If the namespace is a default namespace declaration (isDefault is true) then xmlns="$namespaceURI" is written and the prefix is optional. If isDefault is false, the prefix must be declared and the writer must prepend xmlns to the prefix and write out a standard prefix declaration.
PROCESSING_INSTRUCTION None String target, String data The data does not need to be present and may be null. Target is required and many not be null. The writer will write data section directly after the target, enclosed in appropriate XML 1.0 syntax
COMMENT None String comment If the comment is present (not null) it is written, otherwise an an empty comment is written
START_DOCUMENT None String encoding , boolean standalone, String version A START_DOCUMENT event is not required to be written to the stream. If present the attributes are written inside the appropriate XML declaration syntax
END_DOCUMENT None None Nothing is written to the output
DTD String DocumentTypeDefinition None The DocumentTypeDefinition is written to the output

Specified by:
add in interface javax.xml.stream.XMLEventWriter
Parameters:
e - the event to be added
Throws:
javax.xml.stream.XMLStreamException

add

public void add(javax.xml.stream.XMLEventReader stream)
         throws javax.xml.stream.XMLStreamException
Description copied from interface: javax.xml.stream.XMLEventWriter
Adds an entire stream to an output stream, calls next() on the inputStream argument until hasNext() returns false This should be treated as a convenience method that will perform the following loop over all the events in an event reader and call add on each event.

Specified by:
add in interface javax.xml.stream.XMLEventWriter
Parameters:
stream - the event stream to add to the output
Throws:
javax.xml.stream.XMLStreamException

getPrefix

public java.lang.String getPrefix(java.lang.String uri)
                           throws javax.xml.stream.XMLStreamException
Description copied from interface: javax.xml.stream.XMLEventWriter
Gets the prefix the uri is bound to

Specified by:
getPrefix in interface javax.xml.stream.XMLEventWriter
Parameters:
uri - the uri to look up
Throws:
javax.xml.stream.XMLStreamException

setPrefix

public void setPrefix(java.lang.String prefix,
                      java.lang.String uri)
               throws javax.xml.stream.XMLStreamException
Description copied from interface: javax.xml.stream.XMLEventWriter
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.XMLEventWriter
Parameters:
prefix - the prefix to bind to the uri
uri - the uri to bind to the prefix
Throws:
javax.xml.stream.XMLStreamException

setDefaultNamespace

public void setDefaultNamespace(java.lang.String uri)
                         throws javax.xml.stream.XMLStreamException
Description copied from interface: javax.xml.stream.XMLEventWriter
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.XMLEventWriter
Parameters:
uri - the uri to bind to the default namespace
Throws:
javax.xml.stream.XMLStreamException

setNamespaceContext

public void setNamespaceContext(javax.xml.namespace.NamespaceContext context)
                         throws javax.xml.stream.XMLStreamException
Description copied from interface: javax.xml.stream.XMLEventWriter
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.

Specified by:
setNamespaceContext in interface javax.xml.stream.XMLEventWriter
Parameters:
context - the namespace context to use for this writer
Throws:
javax.xml.stream.XMLStreamException

Specified by:
getNamespaceContext in interface javax.xml.stream.XMLEventWriter
Returns:
the current namespace context

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception
Throws:
java.lang.Exception
