Interface AtomicType

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).
Method Summary
StructuredQNamegetTypeName()
Get the name of this type as a StructuredQName, unless the type is anonymous, in which case return null
booleanisAbstract()
Determine whether the type is abstract, that is, whether it cannot have instances that are not also instances of some concrete subtype
booleanisBuiltInType()
Determine whether the atomic type is a built-in type.
booleanisOrdered()
Determine whether the atomic type is ordered, that is, whether less-than and greater-than comparisons are permitted
booleanisPrimitiveType()
Determine whether the atomic type is a primitive type.
ValidationFailurevalidate(AtomicValue primValue, CharSequence lexicalValue, NameChecker checker)
Validate that a primitive atomic value is a valid instance of a type derived from the same primitive type.

Method Detail

getTypeName

public StructuredQName getTypeName()
Get the name of this type as a StructuredQName, unless the type is anonymous, in which case return null

Returns: the name of the atomic type, or null if the type is anonymous.

isAbstract

public boolean isAbstract()
Determine whether the type is abstract, that is, whether it cannot have instances that are not also instances of some concrete subtype

isBuiltInType

public 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, ...)

isOrdered

public 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

isPrimitiveType

public 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

validate

public ValidationFailure validate(AtomicValue primValue, 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: UnsupportedOperationException in the case of an external object type
