pack-priv final Class ValidatorImpl

Implements com.sun.org.apache.xerces.internal.xs.PSVIProvider.getAttributePSVI.

Doc from com.sun.org.apache.xerces.internal.xs.PSVIProvider.getAttributePSVI.

Provides AttributePSVI given the index of an attribute information item in the current element's attribute list. The method must be called by an application while in the scope of the methods which report the start and end of an element at a point where the attribute list is available. For example, for SAX the method must be called while in the scope of the document handler's startElement call. If the method is called outside of the specified scope, the return value is undefined.

Implements com.sun.org.apache.xerces.internal.xs.PSVIProvider.getAttributePSVIByName.

Doc from com.sun.org.apache.xerces.internal.xs.PSVIProvider.getAttributePSVIByName.

Provides AttributePSVI given the namespace name and the local name of an attribute information item in the current element's attribute list. The method must be called by an application while in the scope of the methods which report the start and end of an element at a point where the attribute list is available. For example, for SAX the method must be called while in the scope of the document handler's startElement call. If the method is called outside of the specified scope, the return value is undefined.

Implements com.sun.org.apache.xerces.internal.xs.PSVIProvider.getElementPSVI.

Doc from com.sun.org.apache.xerces.internal.xs.PSVIProvider.getElementPSVI.

Provides the post schema validation item for the current element information item. The method must be called by an application while in the scope of the methods which report the start and end of an element. For example, for SAX the method must be called within the scope of the document handler's startElement or endElement call. If the method is called outside of the specified scope, the return value is undefined.

@Override

Implements abstract javax.xml.validation.Validator.getErrorHandler.

Doc from javax.xml.validation.Validator.getErrorHandler.

Gets the current ErrorHandler set to this Validator.

Annotations

@Override

Overrides javax.xml.validation.Validator.getFeature.

Doc from javax.xml.validation.Validator.getFeature.

Look up the value of a feature flag.

The feature name is any fully-qualified URI. It is possible for a Validator to recognize a feature name but temporarily be unable to return its value. Some feature values may be available only in specific contexts, such as before, during, or after a validation.

Implementors are free (and encouraged) to invent their own features, using names built on their own URIs.

Annotations

@Override

Exceptions

SAXNotRecognizedException:

If the feature value can't be assigned or retrieved.

SAXNotSupportedException:

When the Validator recognizes the feature name but cannot determine its value at this time.

Overrides javax.xml.validation.Validator.getProperty.

Doc from javax.xml.validation.Validator.getProperty.

Look up the value of a property.

The property name is any fully-qualified URI. It is possible for a Validator to recognize a property name but temporarily be unable to return its value. Some property values may be available only in specific contexts, such as before, during, or after a validation.

Validators are not required to recognize any specific property names.

Implementors are free (and encouraged) to invent their own properties, using names built on their own URIs.

Implements abstract javax.xml.validation.Validator.getResourceResolver.

Doc from javax.xml.validation.Validator.getResourceResolver.

Gets the current LSResourceResolver set to this Validator.

Annotations

@Override

Implements abstract javax.xml.validation.Validator.reset.

Doc from javax.xml.validation.Validator.reset.

Reset this Validator to its original configuration.

Validator is reset to the same state as when it was created with Schema#newValidator(). reset() is designed to allow the reuse of existing Validators thus saving resources associated with the creation of new Validators.

The reset Validator is not guaranteed to have the same LSResourceResolver or ErrorHandler Objects, e.g. Object#equals(Object obj). It is guaranteed to have a functionally equal LSResourceResolver and ErrorHandler.

@Override

Implements abstract javax.xml.validation.Validator.setErrorHandler.

Doc from javax.xml.validation.Validator.setErrorHandler.

Sets the ErrorHandler to receive errors encountered during the validate method invocation.

Error handler can be used to customize the error handling process during a validation. When an ErrorHandler is set, errors found during the validation will be first sent to the ErrorHandler.

The error handler can abort further validation immediately by throwing SAXException from the handler. Or for example it can print an error to the screen and try to continue the validation by returning normally from the ErrorHandler

If any Throwable is thrown from an ErrorHandler, the caller of the validate method will be thrown the same Throwable object.

Validator is not allowed to throw SAXException without first reporting it to ErrorHandler.

When the ErrorHandler is null, the implementation will behave as if the following ErrorHandler is set:

class DraconianErrorHandler implements ErrorHandler {
    public void fatalError( org.xml.sax.SAXParseException e ) throws SAXException {
        throw e;
    }
    public void error( org.xml.sax.SAXParseException e ) throws SAXException {
        throw e;
    }
    public void warning( org.xml.sax.SAXParseException e ) throws SAXException {
        // noop
    }
}

When a new Validator object is created, initially this field is set to null.

Annotations

@Override

Overrides javax.xml.validation.Validator.setFeature.

Doc from javax.xml.validation.Validator.setFeature.

Set the value of a feature flag.

Feature can be used to control the way a Validator parses schemas, although Validators are not required to recognize any specific feature names.

The feature name is any fully-qualified URI. It is possible for a Validator to expose a feature value but to be unable to change the current value. Some feature values may be immutable or mutable only in specific contexts, such as before, during, or after a validation.

Annotations

@Override

Exceptions

SAXNotRecognizedException:

If the feature value can't be assigned or retrieved.

SAXNotSupportedException:

When the Validator recognizes the feature name but cannot set the requested value.

Overrides javax.xml.validation.Validator.setProperty.

Doc from javax.xml.validation.Validator.setProperty.

Set the value of a property.

The property name is any fully-qualified URI. It is possible for a Validator to recognize a property name but to be unable to change the current value. Some property values may be immutable or mutable only in specific contexts, such as before, during, or after a validation.

All implementations that implement JAXP 1.5 or newer are required to support the javax.xml.XMLConstants#ACCESS_EXTERNAL_DTD and javax.xml.XMLConstants#ACCESS_EXTERNAL_SCHEMA properties.

• Access to external DTDs in source or Schema file is restricted to the protocols specified by the javax.xml.XMLConstants#ACCESS_EXTERNAL_DTD property. If access is denied during validation due to the restriction of this property, org.xml.sax.SAXException will be thrown by the validate(Source) method.

  Access to external reference set by the schemaLocation attribute is restricted to the protocols specified by the javax.xml.XMLConstants#ACCESS_EXTERNAL_SCHEMA property. If access is denied during validation due to the restriction of this property, org.xml.sax.SAXException will be thrown by the validate(Source) method.

Exceptions

SAXNotRecognizedException:

SAXNotSupportedException:

When the Validator recognizes the property name but cannot set the requested value.

Implements abstract javax.xml.validation.Validator.setResourceResolver.

Doc from javax.xml.validation.Validator.setResourceResolver.

Sets the LSResourceResolver to customize resource resolution while in a validation episode.

Validator uses a LSResourceResolver when it needs to locate external resources while a validation, although exactly what constitutes "locating external resources" is up to each schema language.

When the LSResourceResolver is null, the implementation will behave as if the following LSResourceResolver is set:

class DumbLSResourceResolver implements LSResourceResolver {
    public org.w3c.dom.ls.LSInput resolveResource(
        String publicId, String systemId, String baseURI) {

        return null; // always return null
    }
}

If a LSResourceResolver throws a RuntimeException (or instances of its derived classes), then the Validator will abort the parsing and the caller of the validate method will receive the same RuntimeException.

When a new Validator object is created, initially this field is set to null.

@Override

Implements abstract javax.xml.validation.Validator.validate.

Doc from javax.xml.validation.Validator.validate.

Validates the specified input and send the augmented validation result to the specified output.

This method places the following restrictions on the types of the Source/Result accepted.

To validate one Source into another kind of Result, use the identity transformer (see javax.xml.transform.TransformerFactory#newTransformer()).

Errors found during the validation is sent to the specified ErrorHandler.

If a document is valid, or if a document contains some errors but none of them were fatal and the ErrorHandler didn't throw any exception, then the method returns normally.

Annotations

@Override

Exceptions

SAXException:

If the ErrorHandler throws a SAXException or if a fatal error is found and the ErrorHandler returns normally.

IOException:

If the validator is processing a SAXSource and the underlying org.xml.sax.XMLReader throws an IOException.
