jdk7u.jaxp.org.apache.xerces.external.jaxp.datatype.DatatypeFactoryImpl

public class DatatypeFactoryImpl
extends DatatypeFactory

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:

1. 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.
2. 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.
3. 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.
4. 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.

Method Detail

newDuration

public Duration newDuration(String lexicalRepresentation)

Obtain a new instance of a Duration specifying the Duration as its string representation, "PnYnMnDTnHnMnS", as defined in XML Schema 1.0 section 3.2.6.1.

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

duration represents a duration of time. The value space of duration is a six-dimensional space where the coordinates designate the Gregorian year, month, day, hour, minute, and second components defined in Section 5.5.3.2 of [ISO 8601], respectively. These components are ordered in their significance by their order of appearance i.e. as year, month, day, hour, minute, and second.

All six values are set and availabe from the created Duration

The XML Schema specification states that values can be of an arbitrary size. Implementations may chose not to or be incapable of supporting arbitrarily large and/or small values. An UnsupportedOperationException will be thrown with a message indicating implementation limits if implementation capacities are exceeded.

Specified by:

newDuration in class DatatypeFactory

Parameters:

lexicalRepresentation - String representation of a Duration.

Returns:

New Duration created from parsing the lexicalRepresentation.

Throws:

IllegalArgumentException - If lexicalRepresentation is not a valid representation of a Duration.

UnsupportedOperationException - If implementation cannot support requested values.

NullPointerException - if lexicalRepresentation is null.

newDuration

public Duration newDuration(long durationInMilliseconds)

Obtain a new instance of a Duration specifying the Duration as milliseconds.

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

duration represents a duration of time. The value space of duration is a six-dimensional space where the coordinates designate the Gregorian year, month, day, hour, minute, and second components defined in Section 5.5.3.2 of [ISO 8601], respectively. These components are ordered in their significance by their order of appearance i.e. as year, month, day, hour, minute, and second.

All six values are set by computing their values from the specified milliseconds and are availabe using the get methods of the created Duration. The values conform to and are defined by:

• ISO 8601:2000(E) Section 5.5.3.2 Alternative format
• W3C XML Schema 1.0 Part 2, Appendix D, ISO 8601 Date and Time Formats
• XMLGregorianCalendar Date/Time Datatype Field Mapping Between XML Schema 1.0 and Java Representation

The default start instance is defined by GregorianCalendar's use of the start of the epoch: i.e., Calendar.YEAR = 1970, Calendar.MONTH = Calendar.JANUARY, Calendar.DATE = 1, etc. This is important as there are variations in the Gregorian Calendar, e.g. leap years have different days in the month = Calendar.FEBRUARY so the result of Duration.getMonths() and Duration.getDays() can be influenced.

Specified by:

newDuration in class DatatypeFactory

Parameters:

durationInMilliseconds - Duration in milliseconds to create.

Returns:

New Duration representing durationInMilliseconds.

newDuration

public Duration newDuration(boolean isPositive,
                   BigInteger years,

                   BigInteger hours,
                   BigInteger minutes,
                   BigDecimal seconds)

Obtain a new instance of a Duration specifying the Duration as isPositive, years, months, days, hours, minutes, seconds.

The XML Schema specification states that values can be of an arbitrary size. Implementations may chose not to or be incapable of supporting arbitrarily large and/or small values. An UnsupportedOperationException will be thrown with a message indicating implementation limits if implementation capacities are exceeded.

Specified by:

newDuration in class DatatypeFactory

Parameters:

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

seconds - of this Duration

Returns:

New Duration created from the specified values.

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.

Create a Duration of type xdt:yearMonthDuration using the specified year and month as defined in XQuery 1.0 and XPath 2.0 Data Model, xdt:yearMonthDuration.

The XML Schema specification states that values can be of an arbitrary size. Implementations may chose not to or be incapable of supporting arbitrarily large and/or small values.

*conversion loss of information. It is not possible to represent a java.util.GregorianCalendar daylight savings timezone id in the XML Schema 1.0 date/time datatype representation.

To compute the return value's TimeZone field,

• when this.getTimezone() != FIELD_UNDEFINED, create a java.util.TimeZone with a custom timezone id using the this.getTimezone().
• else use the GregorianCalendar default timezone value for the host is defined as specified by java.util.TimeZone.getDefault().

Specified by:

newXMLGregorianCalendar in class DatatypeFactory

Parameters:

cal - java.util.GregorianCalendar used to create XMLGregorianCalendar

Returns:

XMLGregorianCalendar created from java.util.GregorianCalendar
