Constant Field Values

mConfig

protected final WriterConfig mConfig

mNsAware

protected final boolean mNsAware

mNsRepairing

protected final boolean mNsRepairing

mEncoding

protected java.lang.String mEncoding

This member variable is to keep information about encoding that seems to be used for the document (or fragment) to output, if known.

mNsContext

protected javax.xml.namespace.NamespaceContext mNsContext

If we are being given info about existing bindings, it'll come as a NamespaceContet.

mDocument

protected final org.w3c.dom.Document mDocument

We need a reference to the document hosting nodes to be able to create new nodes

mCurrElem

protected DOMOutputElement mCurrElem

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.

mOpenElement

protected DOMOutputElement mOpenElement

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 mCurrElem, 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.

protected int[] mAutoNsSeq

for NsRepairing mode

mSuggestedDefNs

isPropertySupported

public boolean isPropertySupported(java.lang.String name)

Description copied from interface: XMLStreamWriter2

Method similar to XMLOutputFactory.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.

Specified by:

isPropertySupported in interface XMLStreamWriter2

setProperty

public boolean setProperty(java.lang.String name,
                           java.lang.Object value)

Description copied from interface: XMLStreamWriter2

Method that can be used to set per-writer properties; a subset of properties one can set via matching XMLOutputFactory2 instance. Exactly which methods are mutable is implementation specific.

Specified by:

setProperty in interface XMLStreamWriter2

Parameters:

name - Name of the property to set

value - Value to set property to.

Returns:

True, if the specified property was succesfully set to specified value; false if its value was not changed

validateAgainst

public XMLValidator validateAgainst(XMLValidationSchema schema)
                             throws javax.xml.stream.XMLStreamException

Description copied from interface: Validatable

Method that will construct a XMLValidator instance from the given schema (unless a validator for that schema has already been added), initialize it if necessary, and make validatable object (reader, writer) call appropriate validation methods from this point on until the end of the document (that is, it's not scoped with sub-trees), or until validator is removed by an explicit call to Validatable.stopValidatingAgainst(org.codehaus.stax2.validation.XMLValidationSchema).

Note that while this method can be called at any point in output processing, validator instances are not required to be able to handle addition at other points than right before outputting the root element.

Specified by:

validateAgainst in interface Validatable

Returns:

Validator instance constructed, if validator was added, or null if a validator for the schema has already been constructed.

Throws:

javax.xml.stream.XMLStreamException

stopValidatingAgainst

public XMLValidator stopValidatingAgainst(XMLValidationSchema schema)
                                   throws javax.xml.stream.XMLStreamException

Description copied from interface: Validatable

Method that can be called by application to stop validating output against a schema, for which Validatable.validateAgainst(org.codehaus.stax2.validation.XMLValidationSchema) was called earlier.

Specified by:

stopValidatingAgainst in interface Validatable

Returns:

Validator instance created from the schema that was removed, if one was in use; null if no such schema in use.

Throws:

javax.xml.stream.XMLStreamException

stopValidatingAgainst

public XMLValidator stopValidatingAgainst(XMLValidator validator)
                                   throws javax.xml.stream.XMLStreamException

Description copied from interface: Validatable

Method that can be called by application to stop validating output using specified validator. The validator passed should be an earlier return value for a call to Validatable.validateAgainst(org.codehaus.stax2.validation.XMLValidationSchema).

Note: the specified validator is compared for identity with validators in use, not for equality.

Specified by:

stopValidatingAgainst in interface Validatable

Returns:

Validator instance found (ie. argument validator) if it was being used for validating current document; null if not.

Throws:

javax.xml.stream.XMLStreamException

setValidationProblemHandler

public ValidationProblemHandler setValidationProblemHandler(ValidationProblemHandler h)

Description copied from interface: Validatable

Method that application can call to define a custom handler for validation problems encountered during validation process.

Specified by:

setValidationProblemHandler in interface Validatable

Parameters:

h - Handler to install, if non null; if null, indicates that the default (implementation-specific) handling should be used

Returns:

Previously set validation problem handler, if any; null if none was set

getLocation

public XMLStreamLocation2 getLocation()

Description copied from interface: XMLStreamWriter2

Method that should return current output location, if the writer keeps track of it; null if it does not.

Specified by:

getLocation in interface XMLStreamWriter2

getEncoding

public java.lang.String getEncoding()

Description copied from interface: XMLStreamWriter2

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)

Specified by:

getEncoding in interface XMLStreamWriter2

writeCData

public void writeCData(char[] text,
                       int start,

                     java.lang.String publicId,
                     java.lang.String internalSubset)
              throws javax.xml.stream.XMLStreamException

Specified by:

writeDTD in interface XMLStreamWriter2

Throws:

javax.xml.stream.XMLStreamException

writeFullEndElement

public void writeFullEndElement()
                         throws javax.xml.stream.XMLStreamException

Description copied from interface: XMLStreamWriter2

Method similar to XMLStreamWriter.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.

Specified by:

writeFullEndElement in interface XMLStreamWriter2

Throws:

javax.xml.stream.XMLStreamException

writeStartDocument

public void writeStartDocument(java.lang.String version,
                               java.lang.String encoding,
                               boolean standAlone)
                        throws javax.xml.stream.XMLStreamException

Specified by:

writeStartDocument in interface XMLStreamWriter2

Throws:

javax.xml.stream.XMLStreamException

writeRaw

public void writeRaw(java.lang.String text)
              throws javax.xml.stream.XMLStreamException

Description copied from interface: XMLStreamWriter2

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.

Specified by:

writeRaw in interface XMLStreamWriter2

Throws:

javax.xml.stream.XMLStreamException

writeRaw

public void writeRaw(java.lang.String text,

                     int length)
              throws javax.xml.stream.XMLStreamException

copyEventFromReader

public void copyEventFromReader(XMLStreamReader2 r,
                                boolean preserveEventData)
                         throws javax.xml.stream.XMLStreamException

Description copied from interface: XMLStreamWriter2

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)

Specified by:

copyEventFromReader in interface XMLStreamWriter2

Parameters:

r - Reader to use for accessing event to copy

preserveEventData - 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:

javax.xml.stream.XMLStreamException
