This class is responsible for scanning the structure and content of document fragments. The scanner acts as the source for the document information which is communicated to the document handler.
This component requires the following features and properties from the component manager that uses it:

Method Detail |
public void setInputSource(XMLInputSource inputSource) throws java.io.IOException
inputSource
- The input source.public boolean scanDocument(boolean complete) throws java.io.IOException, XNIException
complete
- True if the scanner should scan the document
completely, pushing all events to the registered
document handler. A value of false indicates that
that the scanner should only scan the next portion
of the document and return. A scanner instance is
permitted to completely scan a document if it does
not support this "pull" scanning model.public void reset(XMLComponentManager componentManager) throws XMLConfigurationException
componentManager
- The component manager.public java.lang.String[] getRecognizedFeatures()
public void setFeature(java.lang.String featureId, boolean state) throws XMLConfigurationException
Note: Components should silently ignore features that do not affect the operation of the component.
featureId
- The feature identifier.state
- The state of the feature.public java.lang.String[] getRecognizedProperties()
public void setProperty(java.lang.String propertyId, java.lang.Object value) throws XMLConfigurationException
Note: Components should silently ignore properties that do not affect the operation of the component.
propertyId
- The property identifier.value
- The value of the property.public void setDocumentHandler(XMLDocumentHandler documentHandler)
documentHandler
- public XMLDocumentHandler getDocumentHandler()
public void startEntity(java.lang.String name, XMLResourceIdentifier identifier, java.lang.String encoding) throws XNIException
name
- The name of the entity.identifier
- The resource identifier.encoding
- The auto-detected IANA encoding name of the entity
stream. This value will be null in those situations
where the entity encoding is not auto-detected (e.g.
internal entities or a document entity that is
parsed from a java.io.Reader).public void endEntity(java.lang.String name) throws XNIException
name
- The name of the entity.protected XMLDocumentFragmentScannerImpl.Dispatcher createContentDispatcher()
protected void scanXMLDeclOrTextDecl(boolean scanningTextDecl) throws java.io.IOException, XNIException
[23] XMLDecl ::= '<?xml' VersionInfo EncodingDecl? SDDecl? S? '?>' [24] VersionInfo ::= S 'version' Eq (' VersionNum ' | " VersionNum ") [80] EncodingDecl ::= S 'encoding' Eq ('"' EncName '"' | "'" EncName "'" ) [81] EncName ::= [A-Za-z] ([A-Za-z0-9._] | '-')* [32] SDDecl ::= S 'standalone' Eq (("'" ('yes' | 'no') "'") | ('"' ('yes' | 'no') '"')) [77] TextDecl ::= '<?xml' VersionInfo? EncodingDecl S? '?>'
scanningTextDecl
- True if a text declaration is to
be scanned instead of an XML
declaration.protected void scanPIData(java.lang.String target, XMLString data) throws java.io.IOException, XNIException
target
- The PI targetdata
- The string to fill in with the dataprotected void scanComment() throws java.io.IOException, XNIException
[15] Comment ::= '<!--' ((Char - '-') | ('-' (Char - '-')))* '-->'
Note: Called after scanning past '<!--'
protected boolean scanStartElement() throws java.io.IOException, XNIException
[44] EmptyElemTag ::= '<' Name (S Attribute)* S? '/>' [40] STag ::= '<' Name (S Attribute)* S? '>'
Note: This method assumes that the leading '<' character has been consumed.
Note: This method uses the fElementQName and fAttributes variables. The contents of these variables will be destroyed. The caller should copy important information out of these variables before calling this method.
protected void scanAttribute(XMLAttributes attributes) throws java.io.IOException, XNIException
[41] Attribute ::= Name Eq AttValue
Note: This method assumes that the next character on the stream is the first character of the attribute name.
Note: This method uses the fAttributeQName and fQName variables. The contents of these variables will be destroyed.
attributes
- The attributes list for the scanned attribute.protected int scanContent() throws java.io.IOException, XNIException
protected boolean scanCDATASection(boolean complete) throws java.io.IOException, XNIException
Note: This method uses the fString and fStringBuffer variables.
complete
- True if the CDATA section is to be scanned
completely.protected int scanEndElement() throws java.io.IOException, XNIException
[42] ETag ::= '</' Name S? '>'
Note: This method uses the fElementQName variable. The contents of this variable will be destroyed. The caller should copy the needed information out of this variable before calling this method.
protected void scanCharReference() throws java.io.IOException, XNIException
[66] CharRef ::= '' [0-9]+ ';' | '' [0-9a-fA-F]+ ';'
protected void scanEntityReference() throws java.io.IOException, XNIException
protected int handleEndElement(QName element, boolean isEmpty) throws XNIException
Note: This method uses the fQName variable. The contents of this variable will be destroyed.
element
- The element.protected final void setScannerState(int state)
state
- The new scanner state.protected final void setDispatcher(XMLDocumentFragmentScannerImpl.Dispatcher dispatcher)
dispatcher
- The new dispatcher.protected java.lang.String getScannerStateName(int state)
public java.lang.String getDispatcherName(XMLDocumentFragmentScannerImpl.Dispatcher dispatcher)
