PropertyDefinition :: hasType - Does a collection have an index?
The function checks whether a type definition exists for the property (true) or not (false). The function may be called in order to check, whether the type definition exists before calling typeDefinition(). Typically, properties with elementary type do not provide a type definition, but typeName() or internal typeId().
When the function is called with an invalid property definition, it throws an exception.
... fragment ( Property &person ) {
PropertyDefinition pd(person.propertyDefinition());
if ( pd.hasType() )
Application::output(pd.typeDefinition().name());
}
Return value: Success ( bool )
The value is true when the function was executed successfully. Otherwise the value is set to false.
