public interface AtomicType extends SimpleType, ItemType
Interface for atomic types (these are either built-in atomic types or user-defined atomic types). An AtomicType is both an ItemType (a possible type for items in a sequence) and a SchemaType (a possible type for validating and annotating nodes).

validate
ValidationFailure validate(AtomicValue primValue, java.lang.CharSequence lexicalValue, NameChecker checker)
Validate that a primitive atomic value is a valid instance of a type derived from the same primitive type.- Parameters:
primValue
- the value in the value space of the primitive type.lexicalValue
- the value in the lexical space. If null, the string value of primValue is used. This value is checked against the pattern facet (if any)checker
- Used for checking names against XML 1.0 or XML 1.1 rules- Returns:
- null if the value is valid; otherwise, a ValidationFailure object indicating the nature of the error.
- Throws:
java.lang.UnsupportedOperationException
- in the case of an external object type
-
isOrdered
boolean isOrdered()
Determine whether the atomic type is ordered, that is, whether less-than and greater-than comparisons are permitted- Returns:
- true if ordering operations are permitted
-
isAbstract
boolean isAbstract()
Determine whether the type is abstract, that is, whether it cannot have instances that are not also instances of some concrete subtype
-
isPrimitiveType
boolean isPrimitiveType()
Determine whether the atomic type is a primitive type. The primitive types are the 19 primitive types of XML Schema, plus xs:integer, xs:dayTimeDuration and xs:yearMonthDuration; xs:untypedAtomic; and all supertypes of these (xs:anyAtomicType, xs:numeric, ...)- Returns:
- true if the type is considered primitive under the above rules
-
isBuiltInType
boolean isBuiltInType()
Determine whether the atomic type is a built-in type. The built-in atomic types are the 41 atomic types defined in XML Schema, plus xs:dayTimeDuration and xs:yearMonthDuration, xs:untypedAtomic, and all supertypes of these (xs:anyAtomicType, xs:numeric, ...)- Specified by:
isBuiltInType
in interfaceSimpleType
- Returns:
- true if this is a built-in type
