Constructor Detail

ValidatingFilter

public ValidatingFilter()

Method Detail

setErrorCode

public void setErrorCode(String errorCode)

Set the error code to be used for error messages

Parameters:

errorCode - the error code

getErrorCode

protected String getErrorCode()

setInvalid

protected void setInvalid(boolean invalid)

isInvalid

protected boolean isInvalid()

usesTypeAnnotations

public boolean usesTypeAnnotations()

Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events

Specified by:

usesTypeAnnotations in interface Receiver

Overrides:

usesTypeAnnotations in class ProxyReceiver

Returns:

true if the Receiver makes any use of this information. If false, the caller may supply untyped nodes instead of supplying the type annotation. Validation filters overwrite any type annotations arriving in the input event stream, so this instance of the method returns false.

reportValidationError

protected void reportValidationError(ValidationException err,
                                     boolean issueComment,
                                     int locationId)
                              throws XPathException

Report a validation error

Parameters:

err - The validation exception

issueComment - true if the validation error message is to be written as an XML comment to the result document

locationId - identifies the location in the source document or stylesheet/query where the validation error was detected

Throws:

XPathException

reportIfInvalid

protected void reportIfInvalid()
                        throws ValidationException

Throws:

ValidationException
