Class ParseOptions

  • public class ParseOptions
extends java.lang.Object
    This class defines options for parsing and/or validating a source document. Some of the options are relevant only when parsing, some only when validating, but they are combined into a single class because the two operations are often performed together.

        public boolean isContinueAfterValidationErrors()
        Ask whether processing should continue after a validation error. Note that all validation errors are reported to the error() method of the ErrorListener, and processing always continues except when this method chooses to throw an exception. At the end of the document, a fatal error is thrown if (a) there have been any validation errors, and (b) this option is not set.
        Returns:
        true if processing should continue

      • setAddCommentsAfterValidationErrors

        public void setAddCommentsAfterValidationErrors​(boolean keepGoing)
        Say that on validation errors, messages explaining the error should (where possible) be written as comments in the validated source document. This option is only relevant when processing continues after a validation error
        Parameters:
        keepGoing - true if comments should be added
        Since:
        9.3. Default is now false; in previous releases this option was always on.

      • setValidationParams

        public void setValidationParams​(ValidationParams params)
        Set the validation parameters. These are the values of variables declared in the schema using the saxon:param extension, and referenced in XSD assertions (or CTA expressions) associated with user-defined types
        Parameters:
        params - the validation parameters

      • getValidationParams

        public ValidationParams getValidationParams()
        Get the validation parameters. These are the values of variables declared in the schema using the saxon:param extension, and referenced in XSD assertions (or CTA expressions) associated with user-defined types
        Returns:
        the validation parameters

      • setCheckEntityReferences

        public void setCheckEntityReferences​(boolean check)
        Say whether to check elements and attributes of type xs:ENTITY (or xs:ENTITIES) against the unparsed entities declared in the document's DTD. This is normally true when performing standalone schema validation, false when invoking validation from XSLT or XQuery.
        Parameters:
        check - true if entities are to be checked, false otherwise

      • isCheckEntityReferences

        public boolean isCheckEntityReferences()
        Ask whether to check elements and attributes of type xs:ENTITY (or xs:ENTITIES) against the unparsed entities declared in the document's DTD. This is normally true when performing standalone schema validation, false when invoking validation from XSLT or XQuery.
        Returns:
        true if entities are to be checked, false otherwise

      • isStable

        public boolean isStable()
        Ask whether the document (or collection) should be stable, that is, if repeated attempts to dereference the same URI are guaranteed to return the same result. By default, documents and collections are stable.
        Returns:
        true if the document or collection is stable

      • setStable

        public void setStable​(boolean stable)
        Say whether the document (or collection) should be stable, that is, if repeated attempts to dereference the same URI are guaranteed to return the same result. By default, documents and collections are stable.
        Parameters:
        stable - true if the document or collection is stable

      • getInvalidityHandler

        public InvalidityHandler getInvalidityHandler()
        Get the callback for reporting validation errors
        Returns:
        the registered InvalidityHandler

      • setInvalidityHandler

        public void setInvalidityHandler​(InvalidityHandler invalidityHandler)
        Set the callback for reporting validation errors
        Parameters:
        invalidityHandler - the InvalidityHandler to be used for reporting validation failures

      • setApplicableAccumulators

        public void setApplicableAccumulators​(java.util.Set<? extends Accumulator> accumulators)
        Set the list of XSLT 3.0 accumulators that apply to this tree.
        Parameters:
        accumulators - the accumulators that apply; or null if all accumulators apply. (Note, this is not the same as the meaning of #all in the use-accumulators attribute, which refers to all accumulators declared in a given package).

      • getApplicableAccumulators

        public java.util.Set<? extends Accumulator> getApplicableAccumulators()
        Set the list of XSLT 3.0 accumulators that apply to this tree.
        Returns:
        the accumulators that apply; or null if all accumulators apply. (Note, this is not the same as the meaning of #all in the use-accumulators attribute, which refers to all accumulators declared in a given package).

      • setPleaseCloseAfterUse

        public void setPleaseCloseAfterUse​(boolean close)
        Set whether or not the user of this Source is encouraged to close it as soon as reading is finished. Normally the expectation is that any Stream in a StreamSource will be closed by the component that created the Stream. However, in the case of a Source returned by a URIResolver, there is no suitable interface (the URIResolver has no opportunity to close the stream). Also, in some cases such as reading of stylesheet modules, it is possible to close the stream long before control is returned to the caller who supplied it. This tends to make a difference on .NET, where a file often can't be opened if there is a stream attached to it.
        Parameters:
        close - true if the source should be closed as soon as it has been consumed

      • isPleaseCloseAfterUse

        public boolean isPleaseCloseAfterUse()
        Determine whether or not the user of this Source is encouraged to close it as soon as reading is finished.
        Returns:
        true if the source should be closed as soon as it has been consumed

      • close

        public static void close​(javax.xml.transform.Source source)
        Close any resources held by a given Source. This only works if the underlying Source is one that is recognized as holding closable resources.
        Parameters:
        source - the source to be closed
