DatatypeFactorypublic abstract class DatatypeFactory extends Object Factory that creates new javax.xml.datatype Object s that map XML to/from Java Object s.
{@link #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 {@link #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 {@link DatatypeConfigurationException}.
-
If the file ${JAVA_HOME}/lib/jaxp.properties exists, it is loaded in a {@link java.util.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 {@link DatatypeConfigurationException}.
-
The final mechanism is to attempt to instantiate the
Class specified by
{@link #DATATYPEFACTORY_IMPLEMENTATION_CLASS}.
Any Exception thrown during the instantiation process is wrapped as a {@link DatatypeConfigurationException}.

Fields Summary |
---|
public static final String | DATATYPEFACTORY_PROPERTY Default property name as defined in JSR 206: Java(TM) API for XML Processing (JAXP) 1.3.
Default value is javax.xml.datatype.DatatypeFactory . | public static final String | DATATYPEFACTORY_IMPLEMENTATION_CLASS Default implementation class name as defined in
JSR 206: Java(TM) API for XML Processing (JAXP) 1.3.
Implementers should specify the name of an appropriate class
to be instantiated if no other implementation resolution mechanism
succeeds.
Users should not refer to this field; it is intended only to
document a factory implementation detail.
| private static final Pattern | XDTSCHEMA_YMDhttp://www.w3.org/TR/xpath-datamodel/#xdtschema defines two regexps
to constrain the value space of dayTimeDuration ([^YM]*[DT].*)
and yearMonthDuration ([^DT]*). Note that these expressions rely on
the fact that the value must be an xs:Duration, they simply exclude
some Durations. | private static final Pattern | XDTSCHEMA_DTD |
Constructors Summary |

protected DatatypeFactory()Protected constructor to prevent instaniation outside of package.
Use {@link #newInstance()} to create a DatatypeFactory .
|
Methods Summary |
---|
public abstract javax.xml.datatype.Duration | newDuration(java.lang.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 {@link 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 {@link UnsupportedOperationException} will be thrown with a message indicating implementation limits
if implementation capacities are exceeded.
| public abstract javax.xml.datatype.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 {@link Duration}.
The values conform to and are defined by:
The default start instance is defined by {@link GregorianCalendar}'s use of the start of the epoch: i.e.,
{@link java.util.Calendar#YEAR} = 1970,
{@link java.util.Calendar#MONTH} = {@link java.util.Calendar#JANUARY},
{@link java.util.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 = {@link java.util.Calendar#FEBRUARY}
so the result of {@link Duration#getMonths()} and {@link Duration#getDays()} can be influenced.
| public abstract javax.xml.datatype.Duration | newDuration(boolean isPositive, java.math.BigInteger years, java.math.BigInteger months, java.math.BigInteger days, java.math.BigInteger hours, java.math.BigInteger minutes, java.math.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 {@link UnsupportedOperationException} will be thrown with a message indicating implementation limits
if implementation capacities are exceeded.
A null value indicates that field is not set.
| public javax.xml.datatype.Duration | newDuration(boolean isPositive, int years, int months, int days, int hours, int minutes, int seconds)Obtain a new instance of a Duration
specifying the Duration as isPositive, years, months, days, hours, minutes, seconds.

| public static javax.xml.datatype.DatatypeFactory | newInstance()Obtain a new instance of a DatatypeFactory .
The implementation resolution mechanisms are defined in this
Class 's documentation.
try {
return (DatatypeFactory) FactoryFinder.find(
/* The default property name according to the JAXP spec */
DATATYPEFACTORY_PROPERTY,
/* The fallback implementation class name */
DATATYPEFACTORY_IMPLEMENTATION_CLASS);
} catch (FactoryFinder.ConfigurationError e) {
throw new DatatypeConfigurationException(e.getMessage(), e.getException());
}
| public static javax.xml.datatype.DatatypeFactory | newInstance(java.lang.String factoryClassName, java.lang.ClassLoader classLoader)Obtain a new instance of a DatatypeFactory from class name.
This function is useful when there are multiple providers in the classpath.
It gives more control to the application as it can specify which provider
should be loaded.
Once an application has obtained a reference to a DatatypeFactory
it can use the factory to configure and obtain datatype instances.
Tip for Trouble-shooting
Setting the jaxp.debug system property will cause
this method to print a lot of debug messages
to System.err about what it is doing and where it is looking at.
If you have problems try:
java -Djaxp.debug=1 YourProgram ....
try {
return (DatatypeFactory) FactoryFinder.newInstance(factoryClassName, classLoader, false);
} catch (FactoryFinder.ConfigurationError e) {
throw new DatatypeConfigurationException(e.getMessage(), e.getException());
}
| public abstract javax.xml.datatype.XMLGregorianCalendar | newXMLGregorianCalendar()Create a new instance of an XMLGregorianCalendar .
All date/time datatype fields set to {@link DatatypeConstants#FIELD_UNDEFINED} or null.
| public abstract javax.xml.datatype.XMLGregorianCalendar | newXMLGregorianCalendar(java.lang.String lexicalRepresentation)Create a new XMLGregorianCalendar by parsing the String as a lexical representation.
Parsing the lexical string representation is defined in
XML Schema 1.0 Part 2, Section 3.2.[7-14].1,
Lexical Representation.
The string representation may not have any leading and trailing whitespaces.
The parsing is done field by field so that
the following holds for any lexically correct String x:
newXMLGregorianCalendar(x).toXMLFormat().equals(x)
Except for the noted lexical/canonical representation mismatches
listed in
XML Schema 1.0 errata, Section 3.2.7.2.
