Interface AtomicType

All Superinterfaces:

ItemType, SchemaComponent, SchemaType, Serializable, SimpleType

All Known Implementing Classes:

BuiltInAtomicType, ExternalObjectType, UserAtomicType

public interface AtomicType
extends SimpleType, ItemType

Marker 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 Detail

setDerivedTypeLabel

AtomicValue setDerivedTypeLabel(AtomicValue primValue,
                                CharSequence lexicalValue,
                                boolean validate)

Factory method to create values of a derived atomic type. This method is not used to create values of a built-in type, even one that is not primitive.

Parameters:

primValue - the value in the value space of the primitive type.

The type label of this value will be changed. A caller must therefore be absolutely sure that they have exclusive use of the object. If in doubt, call the copy() method first.

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)

validate - true if the value is to be validated against the facets of the derived type; false if the caller knows that the value is already valid.

Returns:

the derived atomic value if validation succeeds, or an ErrorValue otherwise. The ErrorValue encapsulates the exception that occurred; it is the caller's responsibility to check for this.

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
