Interface XMLStreamWriter2

TypedXMLStreamWriter
,Validatable
,XMLStreamWriter
- All Known Implementing Classes:

XMLStreamWriter
,
as well as to configure individual instances.
It also adds limited number of methods that are important for
efficient pass-through processing (such as one needed when routing
SOAP-messages).
Since version 3.0, stream writer will also implement "Typed Access API" on output side.

Method Details
-
isPropertySupported
Method similar toXMLOutputFactory.isPropertySupported(java.lang.String)
, used to determine whether a property is supported by the Writer instance. This means that this method may return false for some properties that the output factory does support: specifically, it should only return true if the value is mutable on per-instance basis. False means that either the property is not recognized, or is not mutable via writer instance. -
setProperty
Method that can be used to set per-writer properties; a subset of properties one can set via matchingXMLOutputFactory2
instance. Exactly which methods are mutable is implementation specific.- Parameters:
name
- Name of the property to setvalue
- Value to set property to.- Returns:
- True, if the specified property was succesfully set to specified value; false if its value was not changed
- Throws:
IllegalArgumentException
- if the property is not supported (or recognized) by the stream writer implementation
-
getLocation
XMLStreamLocation2 getLocation()Method that should return current output location, if the writer keeps track of it; null if it does not. -
getEncoding
String getEncoding()Method that can be called to get information about encoding that this writer is using (or at least claims is using). That is, it returns name of encoding specified when (in order of priority):- Passed to one of factory methods of
XMLOutputFactory
- Passed to
writeStartDocument
method (explicitly or implicity; latter in cases where defaults are imposed by Stax specification)
- Passed to one of factory methods of
-
writeCData
- Throws:
XMLStreamException
-
writeDTD
void writeDTD(String rootName, String systemId, String publicId, String internalSubset) throws XMLStreamException - Throws:
XMLStreamException
-
writeFullEndElement
Method similar toXMLStreamWriter.writeEndElement()
, but that will always write the full end element, instead of empty element. This only matters for cases where the element itself has no content, and if writer is allowed to write empty elements when it encounters such start/end element write pairs.- Throws:
XMLStreamException
-
writeStartDocument
void writeStartDocument(String version, String encoding, boolean standAlone) throws XMLStreamException - Throws:
XMLStreamException
-
writeSpace
Method that can be called to write whitespace-only content. If so, it is to be written as is (with no escaping), and does not contain non-whitespace characters (writer may validate this, and throw an exception if it does).This method is useful for things like outputting indentation.
- Throws:
XMLStreamException
- Since:
- 3.0
-

- Throws:
XMLStreamException
- Since:
- 3.0
-
writeRaw
Method that writes specified content as is, without encoding or deciphering it in any way. It will not update state of the writer (except by possibly flushing output of previous writes, like finishing a start element), nor be validated in any way. As such, care must be taken, if this method is used.Method is usually used when encapsulating output from another writer as a sub-tree, or when passing through XML fragments.
NOTE: since text to be written may be anything, including markup, it can not be reliably validated. Because of this, validator(s) attached to the writer will NOT be informed about writes.

- Throws:

-
copyEventFromReader
Method that essentially copies event that the specified reader has just read. This can be both more convenient (no need to worry about details) and more efficient than separately calling access methods of the reader and write methods of the writer, since writer may know more about reader than the application (and may be able to use non-public methods)- Parameters:
r
- Reader to use for accessing event to copypreserveEventData
- If true, writer is not allowed to change the state of the reader (so that all the data associated with the current event has to be preserved); if false, writer is allowed to use methods that may cause some data to be discarded. Setting this to false may improve the performance, since it may allow full no-copy streaming of data, especially textual contents.- Throws:
XMLStreamException
-
closeCompletely
Method similar toXMLStreamWriter.close()
, except that this method also does close the underlying output destination (stream) if it has not yet been closed. It is specifically necessary to call this method if the parsing ends in an exception to ensure that the output destination does get properly closed, even if the stream writer would otherwise close it (as is the case for destinations it manages where calling application has no access)- Throws:
XMLStreamException
-
