loads any supported grammar (except XML DTD)
by automatically detecting the schema language.
The static version of loadVGM/loadSchema methods provides simple ways to
load a grammar.
Another way to use GrammarLoader is
- To instanciate an object of GrammarLoader
- call setXXX methods to configure the parameters
- call loadSchema/loadVGM methods (possibly multiple times) to
load grammars.
This approach will give you finer control.
getSAXParserFactory
public SAXParserFactory getSAXParserFactory()
getStrictCheck
public boolean getStrictCheck()
loadSchema
public static Grammar loadSchema(InputSource source)
throws SAXException,
ParserConfigurationException,
IOException
loadSchema
public static Grammar loadSchema(InputSource source,
GrammarReaderController controller)
throws SAXException,
ParserConfigurationException,
IOException
returns a thread-safe AGM object, depending on the language used.
loadSchema
public static Grammar loadSchema(String url)
throws SAXException,
ParserConfigurationException,
IOException
parses the specified schema and returns the result as a Grammar object.
This method uses the default SAX parser and throws an exception
if there is an error in the schema.
- a non-null valid Grammar.
loadSchema
public static Grammar loadSchema(String source,
GrammarReaderController controller)
throws SAXException,
ParserConfigurationException,
IOException
returns a thread-safe AGM object, depending on the language used.
loadSchema
public static Grammar loadSchema(String url,
GrammarReaderController controller,
SAXParserFactory factory)
throws SAXException,
ParserConfigurationException,
IOException
parses the specified schema and returns the result as a Grammar object.
- null if there was an error in the grammar.
loadVGM
public static REDocumentDeclaration loadVGM(String url)
throws SAXException,
ParserConfigurationException,
IOException
parses the specified schema and returns the result as a VGM.
This method uses the default SAX parser and throws an exception
if there is an error in the schema.
- non-null valid VGM object.
loadVGM
public static REDocumentDeclaration loadVGM(String url,
GrammarReaderController controller,
SAXParserFactory factory)
throws SAXException,
ParserConfigurationException,
IOException
parses the specified schema and returns the result as a VGM.
This method is an utility method for those applications which
don't need AGM (e.g., a single thread application).
- null if there was an error in the grammar.
parse
public Grammar parse(InputSource source)
throws SAXException,
ParserConfigurationException,
IOException
parse
public Grammar parse(String url)
throws SAXException,
ParserConfigurationException,
IOException
setController
public void setController(GrammarReaderController controller)
sets the GrammarReaderController object that will control
various aspects of the parsing. If not set, no error report will be
done.
setPool
public void setPool(ExpressionPool pool)
Sets the ExpressionPool object that will be used during the loading process.
If not set, a fresh one is used for each time the loadXXX method is called.
setSAXParserFactory
public void setSAXParserFactory(SAXParserFactory factory)
sets the factory object which is used to create XML parsers
to parse schema files.
The factory must be configured to namespace aware.
If no SAXParserFactory is set, then the default parser is used.
(The parser that can be obtained by SAXParserFactory.newInstance()).
setStrictCheck
public void setStrictCheck(boolean value)
Sets the strict check flag. If set to true, schema readers will apply
stricter checks so that it can find errors in the schema. If set to false,
readers will skip some of the checks.
When this flag is set to false, which is the default, the reader may accept
incorrect schemas.
