AtomicType

All Superinterfaces:

ItemType, SchemaComponent, SchemaType, java.io.Serializable, SimpleType

All Known Implementing Classes:

BuiltInAtomicType, ExternalObjectType
```
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

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`isAbstract()`	Determine whether the type is abstract, that is, whether it cannot have instances that are not also instances of some concrete subtype
`boolean`	`isBuiltInType()`	Determine whether the atomic type is a built-in type.
`boolean`	`isOrdered()`	Determine whether the atomic type is ordered, that is, whether less-than and greater-than comparisons are permitted
`boolean`	`isPrimitiveType()`	Determine whether the atomic type is a primitive type.
`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.

  - 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 interface SimpleType
    
    Returns:
    
    true if this is a built-in type
