Hi,
Thanks everybody for your help with my previous questions.
I am currently attempting to retrieve information from attribute types, in
particular their facets. I am aware of the type heirachy i.e. anySimpleType -->
decimal --> integer and have been able to retrieve the individual type objects.
I make the assumption that facets are solely attached to the type in which they
are defined. E.g. given the type definition below, maxInclusive=0 would be
attached to the 'negIntegerType' object and not any of the ancestor type
objects.
<simpleType name="negIntegerType">
<restriction base="integer">
<maxInclusive value="0"/>
</restriction>
</simpleType>
<attribute name="elMin" type="negIntegerType" use="required"/>
My problem comes when tyring to call getLexicalFacetValue() using facets that
are not associated with the given type. To illustrate I will use the example
above, I would expect calling getLexicalFacetValue(FACET_MAXINCLUSIVE) on a
'decimal' type object to return null as stated in the Javadoc but instead it
throws a null pointer exception.
Below is the code I'm using and the stack trace that I get:
System.out.println("::::::::::::: TYPE NAME: " + typeDef.getName());
// Make sure that the value can be turned into a decimal.
Double.parseDouble(attributeValue.toString());
System.out.println("^^^^ TODO: Add validation logic");
String maxInclusive =
typeDef.getLexicalFacetValue(XSSimpleTypeDefinition.FACET_MAXINCLUSIVE);
if(maxInclusive != null)
{
System.out.println("Max. inclusive facet found!!!");
}
else
{
System.out.println("Max. inclusive facet NOT found!!!");
}
java.lang.NullPointerException
