Throws:

SAXException

text

private void text()
           throws SAXException

Throws:

SAXException

endDocument

public void endDocument()

Specified by:

endDocument in interface ContentHandler

setDocumentLocator

public void setDocumentLocator(Locator loc)

Specified by:

setDocumentLocator in interface ContentHandler

startDocument

public void startDocument()
                   throws SAXException

Specified by:

startDocument in interface ContentHandler

Throws:

SAXException

processingInstruction

public void processingInstruction(String target,
                                  String date)

Specified by:

processingInstruction in interface ContentHandler

skippedEntity

public void skippedEntity(String name)

Specified by:

startPrefixMapping in interface ContentHandler

endPrefixMapping

public void endPrefixMapping(String prefix)

Specified by:

endPrefixMapping in interface ContentHandler

reset

public void reset()

Description copied from interface: Validator

Cleans up after validating a document. After completing validation of a document, reset must be called. After calling reset(), another document may be validated. Calling this method may create new ContentHandler and DTDHandler objects or may simply reinitialize the state of the existing objects.

Specified by:

reset in interface Validator

getContentHandler

public ContentHandler getContentHandler()

Description copied from interface: Validator

Returns the ContentHandler that will receive the XML document. Information about the XML document to be validated must be reported by calling methods on the returned ContentHandler. When validation of an XML document has been completed (either endDocument() has been called or validation has been abandoned prematurely), reset() must be called. If no calls are made on the ContentHandler, then reset() need not be called. Implementations should allocate resources that require cleanup (e.g. threads, open files) lazily, typically in startDocument(). This method does not change the state of the Validator: the same object will always be returned unless reset is called.

Specified by:

getContentHandler in interface Validator

Returns:

a ContentHandler, never null

See Also:

Validator.reset()

getDTDHandler

public DTDHandler getDTDHandler()

Description copied from interface: Validator

Returns a DTDHandler. Information about the DTD must be reported by calling methods on the returned object, unless null is returned. The same object will always be returned unless reset is called: this method does not change the state of the Validator.

Specified by:

getDTDHandler in interface Validator

Returns:

a DTDHandler, maybe null if DTD information is not significant to the Validator

error

private void error(String key)
            throws SAXException

Throws:

SAXException

error

private void error(SAXParseException e)
            throws SAXException

Throws:

SAXException

setMemo

private boolean setMemo(PatternMemo m)

findElement

private Pattern findElement(Name name)

resolveNamespacePrefix

public String resolveNamespacePrefix(String prefix)

Description copied from interface: ValidationContext

Resolves a namespace prefix to the corresponding namespace URI. This method is used for validating the QName type, for example.

If the prefix is "" (empty string), it indicates an unprefixed value. The callee should resolve it as for an unprefixed element, rather than for an unprefixed attribute.

If the prefix is "xml", then the callee must resolve this prefix into "http://www.w3.org/XML/1998/namespace", as defined in the XML Namespaces Recommendation.

Specified by:

resolveNamespacePrefix in interface ValidationContext

Returns:

namespace URI of this prefix. If the specified prefix is not declared, the implementation must return null.

getBaseUri

public String getBaseUri()

Description copied from interface: ValidationContext

Returns the base URI of the context. The null string may be returned if no base URI is known.

Specified by:

getBaseUri in interface ValidationContext

addDatatypeError

public final void addDatatypeError(String message,
                                   DatatypeException exception)

push

private final void push(Name name)

pop

private final Name pop()

peek

private final Name peek()
