ClassDescriptorImpl

public ClassDescriptorImpl(Class javaClass,
                           FieldDescriptor[] fields,
                           FieldDescriptor[] identities,
                           ClassDescriptor extend,
                           ClassDescriptor depend,
                           AccessMode accessMode)
            throws MappingException
Constructs a new descriptor for the specified class. When describing inheritence, the descriptor of the parent class should be used and only the fields added in this object must be supplied here.
Parameters:
javaClass - The Java type of this class
fields - The fields described for this class
extend - The descriptor of the class which this class extends,
accessMode - The access mode for this class (null is shared) or null if this is a top-level class
Throws:
MappingException - The extended descriptor does not match a parent class of this type

ClassDescriptorImpl

public ClassDescriptorImpl(Class javaClass,
                           FieldDescriptor[] fields,
                           FieldDescriptor[] identities,
                           ClassDescriptor extend,

                           AccessMode accessMode,
                           boolean verifyConstructable)
            throws MappingException
Constructs a new descriptor for the specified class. When describing inheritence, the descriptor of the parent class should be used and only the fields added in this object must be supplied here.
Parameters:
javaClass - The Java type of this class
fields - The fields described for this class
extend - The descriptor of the class which this class extends,
accessMode - The access mode for this class (null is shared) or null if this is a top-level class
Throws:
MappingException - The extended descriptor does not match a parent class of this type
