public final class DOMForest extends Object
Builds a DOM forest and maintains association from system IDs to DOM trees.A forest is a transitive reflexive closure of referenced documents. IOW, if a document is in a forest, all the documents referenced from it is in a forest, too. To support this semantics,
DOMForest
usesInternalizationLogic
to find referenced documents.Some documents are marked as "root"s, meaning those documents were put into a forest explicitly, not because it is referenced from another document. (However, a root document can be referenced from other documents, too.)

Method Detail
-
get
public Document get(String systemId)
Gets the DOM tree associated with the specified system ID, or null if none is found.
-
getRootDocuments
public Set<String> getRootDocuments()
Returns a read-only set of root document system IDs.
-
getOneDocument
public Document getOneDocument()
Picks one document at random and returns it.
-
checkSchemaCorrectness
public boolean checkSchemaCorrectness(ErrorReceiver errorHandler)
Checks the correctness of the XML Schema documents and return true if it's OK.This method performs a weaker version of the tests where error messages are provided without line number information. So whenever possible use
SchemaConstraintChecker
.- See Also:
SchemaConstraintChecker
-
getSystemId
public String getSystemId(Document dom)
Gets the system ID from which the given DOM is parsed.Poor-man's base URI.
-
parse
public Document parse(InputSource source, boolean root) throws SAXException
- Throws:
SAXException
-
parse
public Document parse(String systemId, boolean root) throws SAXException, IOException
Parses an XML at the given location ( and XMLs referenced by it) into DOM trees and stores them to this forest.- Returns:
- the parsed DOM document object.
- Throws:
SAXException
IOException
-
getParserHandler
public DOMForest.Handler getParserHandler(String systemId, boolean root)
Returns aContentHandler
to feed SAX events into.The client of this class can feed SAX events into the handler to parse a document into this DOM forest.
-
parse
public Document parse(String systemId, InputSource inputSource, boolean root) throws SAXException
Parses the given document and add it to the DOM forest.- Returns:
- null if there was a parse error. otherwise non-null.
- Throws:
SAXException
-
parse
public Document parse(String systemId, XMLStreamReader parser, boolean root) throws XMLStreamException
- Throws:
XMLStreamException
-
transform
public SCDBasedBindingSet transform(boolean enableSCD)
Performs internalization. This method should be called only once, only after all the schemas are parsed.- Returns:
- the returned bindings need to be applied after schema components are built.
-
weakSchemaCorrectnessCheck
public void weakSchemaCorrectnessCheck(SchemaFactory sf)
Performs the schema correctness check by using JAXP 1.3.This is "weak", because
SchemaFactory.newSchema(Source[])
doesn't handle inclusions very correctly (it ends up parsing it from its original source, not in this tree), and because it doesn't handle two documents for the same namespace very well.We should eventually fix JAXP (and Xerces), but meanwhile this weaker and potentially wrong correctness check is still better than nothing when used inside JAX-WS (JAXB CLI and Ant does a better job of checking this.)
To receive errors, use
SchemaFactory.setErrorHandler(ErrorHandler)
.
-
createSAXSource
@NotNull public SAXSource createSAXSource(String systemId)
Creates aSAXSource
that, when parsed, reads from this (instead of parsing the original source identified by the system ID.)
-
createParser
public XMLParser createParser()
CreatesXMLParser
for XSOM which reads documents from this DOMForest rather than doing a fresh parse. The net effect is that XSOM will read transformed XML Schemas instead of the original documents.
-
getEntityResolver
public EntityResolver getEntityResolver()
-
setEntityResolver
public void setEntityResolver(EntityResolver entityResolver)
-
getErrorHandler
public ErrorReceiver getErrorHandler()
-
setErrorHandler
public void setErrorHandler(ErrorReceiver errorHandler)
-
listDocuments
public Document[] listDocuments()
Gets all the parsed documents.
-
listSystemIDs
public String[] listSystemIDs()
Gets all the system IDs of the documents.
-
dump
public void dump(OutputStream out) throws IOException
Dumps the contents of the forest to the specified stream. This is a debug method. As such, error handling is sloppy.- Throws:
IOException
