DatatypeFactoryImpl

https://xerces.apache.org/xerces2-j/: Xerces2 is the next generation of high performance, fully compliant XML parsers in the Apache Xerces family. This new version of Xerces introduces the Xerces Native Interface (XNI), a complete framework for building parser components and configurations that is extremely modular and easy to program. The Apache Xerces2 parser is the reference implementation of XNI but other parser components, configurations, and parsers can be written using the Xerces Native Interface. For complete design and implementation documents, refer to the XNI Manual. Xerces2 is a fully conforming XML Schema 1.0 processor. A partial experimental implementation of the XML Schema 1.1 Structures and Datatypes Working Drafts (December 2009) and an experimental implementation of the XML Schema Definition Language (XSD): Component Designators (SCD) Candidate Recommendation (January 2010) are provided for evaluation. For more information, refer to the XML Schema page. Xerces2 also provides a complete implementation of the Document Object Model Level 3 Core and Load/Save W3C Recommendations and provides a complete implementation of the XML Inclusions (XInclude) W3C Recommendation. It also provides support for OASIS XML Catalogs v1.1. Xerces2 is able to parse documents written according to the XML 1.1 Recommendation, except that it does not yet provide an option to enable normalization checking as described in section 2.13 of this specification. It also handles namespaces according to the XML Namespaces 1.1 Recommendation, and will correctly serialize XML 1.1 documents if the DOM level 3 load/save APIs are in use.

Factory that creates new javax.xml.datatype Objects that map XML to/from Java Objects.
DatatypeFactory.newInstance() is used to create a new DatatypeFactory.
The following implementation resolution mechanisms are used in the following order:

    If the system property specified by DatatypeFactory.DATATYPEFACTORY_PROPERTY, "javax.xml.datatype.DatatypeFactory", exists, a class with the name of the property's value is instantiated. Any Exception thrown during the instantiation process is wrapped as a DatatypeConfigurationException. 
    If the file ${JAVA_HOME}/lib/jaxp.properties exists, it is loaded in a Properties Object.
     The Properties Object  is then queried for the property as documented in the prior step
     and processed as documented in the prior step.
   
   
     The services resolution mechanism is used, e.g. META-INF/services/java.xml.datatype.DatatypeFactory. Any Exception thrown during the instantiation process is wrapped as a DatatypeConfigurationException. 
   
     The final mechanism is to attempt to instantiate the Class specified by DatatypeFactory.DATATYPEFACTORY_IMPLEMENTATION_CLASS, "javax.xml.datatype.DatatypeFactoryImpl". Any Exception thrown during the instantiation process is wrapped as a DatatypeConfigurationException.

XML Schema Part 2: Datatypes, 3.2.6 duration, defines duration as:

Gregorian year, month, day, hour, minute, and second components defined in Section 5.5.3.2 of [ISO 8601], respectively.

Params:	lexicalRepresentation – `String` representation of a `Duration`.
Throws:	IllegalArgumentException – If `lexicalRepresentation` is not a valid representation of a `Duration`. UnsupportedOperationException – If implementation cannot support requested values. NullPointerException – if `lexicalRepresentation` is `null`.
Returns:	New `Duration` created from parsing the `lexicalRepresentation`.

Params:	durationInMilliseconds – Duration in milliseconds to create.
Returns:	New `Duration` representing `durationInMilliseconds`.

Params:	isPositive – Set to `false` to create a negative duration. When the length of the duration is zero, this parameter will be ignored. years – of this `Duration` months – of this `Duration` days – of this `Duration` hours – of this `Duration` minutes – of this `Duration` seconds – of this `Duration`
Throws:	IllegalArgumentException – If values are not a valid representation of a `Duration`. UnsupportedOperationException – If implementation cannot support requested values. NullPointerException – If any values are `null`.
See Also:	newDuration(boolean isPositive, BigInteger years, BigInteger months, BigInteger days, BigInteger hours, BigInteger minutes, BigDecimal seconds)
Returns:	New `Duration` created from the specified values.

Params:	lexicalRepresentation – Lexical representation of one the eight XML Schema date/time datatypes.
Throws:	IllegalArgumentException – If the `lexicalRepresentation` is not a valid `XMLGregorianCalendar`. NullPointerException – If `lexicalRepresentation` is `null`.
Returns:	`XMLGregorianCalendar` created from the `lexicalRepresentation`.

Params:	cal – `java.util.GregorianCalendar` used to create `XMLGregorianCalendar`
Throws:	NullPointerException – If `cal` is `null`.
Returns:	`XMLGregorianCalendar` created from `java.util.GregorianCalendar`

Params:	year – of `XMLGregorianCalendar` to be created. month – of `XMLGregorianCalendar` to be created. day – of `XMLGregorianCalendar` to be created. hour – of `XMLGregorianCalendar` to be created. minute – of `XMLGregorianCalendar` to be created. second – of `XMLGregorianCalendar` to be created. millisecond – of `XMLGregorianCalendar` to be created. timezone – of `XMLGregorianCalendar` to be created.
Throws:	IllegalArgumentException – If any individual parameter's value is outside the maximum value constraint for the field as determined by the Date/Time Data Mapping table in `XMLGregorianCalendar` or if the composite values constitute an invalid `XMLGregorianCalendar` instance as determined by `XMLGregorianCalendar.isValid()`.
Returns:	`XMLGregorianCalendar` created from specified values.
