Method Detail

monitor

java.lang.Object monitor()

Returns the synchronization object for the document. If concurrent multithreaded access to a document is required, the access should should be protected by synchronizing on this monitor() object. There is one monitor per XML document tree.

documentProperties

XmlDocumentProperties documentProperties()

Returns the XmlDocumentProperties object for the document this token source is associated with.

newCursor

XmlCursor newCursor()

Returns a new XML cursor. A cursor provides random access to all the tokens in the XML data, plus the ability to extract strongly-typed XmlObjects for the data. If the data is not read-only, the XML cursor also allows modifications to the data. Using a cursor for the first time typically forces the XML document into memory.

newXMLInputStream

org.apache.poi.xmlbeans.xml.stream.XMLInputStream newXMLInputStream()

Deprecated. XMLInputStream was deprecated by XMLStreamReader from STaX - jsr173 API.

Returns a new XmlInputStream. The stream starts at the current begin-tag or begin-document position and ends at the matching end-tag or end-document. This is a fail-fast stream, so if the underlying data is changed while the stream is being read, the stream throws a ConcurrentModificationException. Throws an IllegalStateException if the XmlTokenSource is not positioned at begin-tag or begin-document (e.g., if it is at an attribute).

newXMLStreamReader

javax.xml.stream.XMLStreamReader newXMLStreamReader()

Returns a new XMLStreamReader. The stream starts at the current begin-tag or begin-document position and ends at the matching end-tag or end-document. This is a fail-fast stream, so if the underlying data is changed while the stream is being read, the stream throws a ConcurrentModificationException.

xmlText

java.lang.String xmlText()

Returns standard XML text.

The text returned represents the document contents starting at the current begin-tag or begin-document and ending at the matching end-tag or end-document. This is same content as newReader, but it is returned as a single string.

Throws an IllegalStateException if the XmlTokenSource is not positioned at begin-tag or begin-document (e.g., if it is at an attribute).

Note that this method does not produce XML with the XML declaration, including the encoding information. To save the XML declaration with the XML, see save(OutputStream) or save(OutputStream, XmlOptions).

newInputStream

java.io.InputStream newInputStream()

Returns a new stream containing standard XML text, encoded according to the given encoding. The byte stream contains contents starting at the current begin-tag or begin-document and ending at the matching end-tag or end-document. The specified encoding is used and also emitted in a PI at the beginning of the stream. This is a fail-fast stream, so if the underlying data is changed while the stream is being read, the stream throws a ConcurrentModificationException. Throws an IllegalStateException if the XmlTokenSource is not positioned at begin-tag or begin-document (e.g., if it is at an attribute).

newReader

java.io.Reader newReader()

Returns a new character reader containing XML text. The contents of the reader represents the document contents starting at the current begin-tag or begin-document and ending at the matching end-tag or end-document. No encoding annotation will be made in the text itself. This is a fail-fast reader, so if the underlying data is changed while the reader is being read, the reader throws a ConcurrentModificationException. Throws an IllegalStateException if the XmlTokenSource is not positioned at begin-tag or begin-document (e.g., if it is at an attribute).

newDomNode

Node newDomNode()

Returns a W3C DOM Node containing the XML represented by this source. This is a copy of the XML, it is not a live with the underlying store of this token source. If this is the document node, then a Document is returned, else a DocumentFragment is returned.

getDomNode

Node getDomNode()

Returns a W3C DOM Node containing the XML represented by this source. This is a live DOM node, not a copy. Any changes made through this node are immediately reflected in the document associated with this token source. Depending on the kind of token this XmlTokenSource represents, an appropriate node will be returned.

save

void save(ContentHandler ch,
          LexicalHandler lh)
   throws SAXException

Writes the XML represented by this source to the given SAX content and lexical handlers. Note that this method does not save the XML declaration, including the encoding information. To save the XML declaration with the XML, see save(OutputStream), save(OutputStream, XmlOptions), save(File) or save(File, XmlOptions).

Throws:

SAXException

save

void save(java.io.File file)
   throws java.io.IOException

Writes the XML represented by this source to the given File. This method will save the XML declaration, including encoding information, with the XML.

Throws:

java.io.IOException

save

void save(java.io.OutputStream os)
   throws java.io.IOException

Writes the XML represented by this source to the given output stream. This method will save the XML declaration, including encoding information, with the XML.

Throws:

java.io.IOException

save

void save(java.io.Writer w)
   throws java.io.IOException

Writes the XML represented by this source to the given output. Note that this method does not save the XML declaration, including the encoding information. To save the XML declaration with the XML, see save(OutputStream), save(OutputStream, XmlOptions), save(File) or save(File, XmlOptions).

Throws:

java.io.IOException

newXMLInputStream

org.apache.poi.xmlbeans.xml.stream.XMLInputStream newXMLInputStream(XmlOptions options)

Deprecated. XMLInputStream was deprecated by XMLStreamReader from STaX - jsr173 API.

Just like newXMLInputStream() but with any of a number of options. Use the options parameter to specify the following:

To specify this	Use this method
The character encoding to use when converting the character data in the XML to bytess.	XmlOptions.setCharacterEncoding(java.lang.String)
Prefix-to-namespace mappings that should be assumed when saving this XML. This is useful when the resulting XML will be part of a larger XML document, ensuring that this inner document will take advantage of namespaces defined in the outer document.	XmlOptions.setSaveImplicitNamespaces(java.util.Map)
Suggested namespace prefixes to use when saving. Used only when a namespace attribute needs to be synthesized.	XmlOptions.setSaveSuggestedPrefixes(java.util.Map)
That namespace attributes should occur first in elements when the XML is saved. By default, they occur last.	XmlOptions.setSaveNamespacesFirst()
The XML should be pretty printed when saved. Note that this should only be used for debugging.	XmlOptions.setSavePrettyPrint()
The number of spaces to use when indenting for pretty printing. The default is 2.	XmlOptions.setSavePrettyPrintIndent(int)
The additional number of spaces indented from the left for pretty printed XML.	XmlOptions.setSavePrettyPrintOffset(int)
To minimize the number of namespace attributes generated for the saved XML. Note that this can reduce performance significantly.	XmlOptions.setSaveAggresiveNamespaces()
To reduce the size of the saved document by allowing the use of the default namespace. Note that this can potentially change the semantic meaning of the XML if unprefixed QNames are present as the value of an attribute or element.	XmlOptions.setUseDefaultNamespace()
To filter out processing instructions with the specified target name.	XmlOptions.setSaveFilterProcinst(java.lang.String)
Change the QName of the synthesized root element when saving. This replaces "xml-fragment" with "fragment" in the namespace http://www.openuri.org/fragment	XmlOptions.setSaveUseOpenFrag()
Saving should begin on the element's contents.	XmlOptions.setSaveInner()
Saving should begin on the element, rather than its contents.	XmlOptions.setSaveOuter()
To rename the document element, or to specify the document element for this XML.	XmlOptions.setSaveSyntheticDocumentElement(javax.xml.namespace.QName)

Parameters:

options - Any of the described options.

Returns:

A new validating XMLInputStream.

It is very different from the save methods which produce XML text which only approximates the actual state of the document.
