public interface XSDatatype extends Serializable, DatabindableDatatype
The most important methods are defined in the
org.relaxng.datatype.Datatype
interface.
This interface provides additional information which is not covered by
org.relaxng.datatype.Datatype interface.
Also, this interface provides various simple type component properties
which are defined in the spec.
Application can use this interface to interact with datatype objects.

returns if the specified facet is applicable to this datatype.
|
boolean | isFinal(int derivationType)
checks if this type is declared as final for the specified kind of derivation.

This method does the reverse operation of the createValue method. The returned string is not necessarily the canonical representation. Also note that the implementation may accept invalid values without throwing IllegalArgumentException. To make sure that the result is actually a valid representation, call the isValid method.
Be careful not to confuse this method with The serializeJavaObject method, which is defined in the DatabindableDatatype method.
Parameters: context Context information that will be possibly used for the conversion. Currently, this object is used only by QName, but may be extended in the future.
Throws: IllegalArgumentException if the type of the given object is not the expected one. For example, this exception is thrown if you pass a BigInteger object to the "gYear" type.
This method is an ad-hoc method and there is no corresponding property in the spec.
This method traverses the inheritance chain from this datatype to the root type (anySimpleType) and return the first built-in type it finds.
For example, if you derive a type Foo from NCName and Bar from Foo, then this method returns NCName.
Returns: Always return non-null valid object.
This method is intended to capture the semantics of the base type definition property of the simple type component, but there is an important difference.
Specifically, if you derive a type D from another type B, then calling D.getBaseType() does not necessarily return B. Instead, it may return an intermediate object (that represents a facet). Calling the getBaseType method recursively will eventually return B.
Returns: null if no such facet object exists.
In the terminology of the spec, this method returns the name property of this simple type component. If the name property is absent, this method returns null.
Returns: VARIETY_ATOMIC, VARIETY_LIST, or VARIETY_UNION.
This method can return false even if the datatype actually accepts any string. That is, it's perfectly OK for any datatype to return false from this method.
This method is an implementation of "Type Derivation OK (Simple)" of the spec. Therefore use caution if what you want is a casual method because this method may cause a lot of unintuitive result.
Note to implementors Use the static version of this method defined in the XSDatatypeImpl class. You don't need to implement this method from scratch.
Parameters: restrictionAllowed
This test needs "a subset of {extension,restriction,list,union}
(of which only restriction is actually relevant). If this flag is
set to true, this method behaves as if the empty set is passed as the set.
This is usually what you want if you're simply trying to check the
derivation relationship.
If this flag is set to false, this method behaves as if {restriction}
is passed as the set.
Returns:
In the terminology of the spec, this method can be used to examine the final property of this component.
Parameters: derivationType one of pre-defined values (DERIVATION_BY_XXX).
