PropertyDefinition :: isBaseType - Is property base class in a complex data type
In ODABA, base classes (base structures) are considered as properties. The function checks, whether the property is defined as base class (shared or exclusive).
In order to determine whether the base class is shared, the baseCollectionPath() can be checked. Shared base class propertiesalways have got a base collection.
If the function is not called with a valid database property definition it throws an exception.
Return value: Success ( bool )
The value is true when the function was executed successfully. Otherwise the value is set to false.
