public class ErrorType
extends BuiltinAtomicType

A dummy datatype that can be used to recover from errors. This datatype accepts any values and any facets. The TypeIncubator class also recognizes this class and any operation on ErrorType will never cause any error and silently return another ErrorType.

Method Detail

_createValue

protected Object _createValue(String content,
                              ValidationContext context)
Description copied from class: XSDatatypeImpl
converts a whitespace-processed lexical value into the corresponding value object

Specified by:
_createValue in class XSDatatypeImpl

checkFormat

protected boolean checkFormat(String literal,
                              ValidationContext context)
Specified by:
checkFormat in class XSDatatypeImpl

convertToLexicalValue

public String convertToLexicalValue(Object valueObject,
                                    SerializationContext context)
                             throws IllegalArgumentException
Description copied from interface: XSDatatype
converts value object back to the corresponding value in the lexical space.

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.

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.

isFacetApplicable

public int isFacetApplicable(String facetName)
Description copied from interface: XSDatatype
returns if the specified facet is applicable to this datatype.

Returns:
APPLICABLE
if the facet is applicable
FIXED
if the facet is already fixed (that is,not applicable)
NOT_ALLOWED
if the facet is not applicable to this datatype at all. this value is also returned for unknown facets.

getBaseType

public XSDatatype getBaseType()
Description copied from interface: XSDatatype
gets the base type of this type. This method returns null if this object represents the simple ur-type.

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.


getJavaObjectType

public Class getJavaObjectType()
Description copied from interface: DatabindableDatatype
gets the type of the objects that are created by the createJavaObject method.
