What's wrong with:

class Enum(RootFragment):
__jpaTypes = {
# complete!
'CascadeType': Enum("javax.persistence.CascadeType"),
'DiscriminatorType':
Enum("javax.persistence.DiscriminatorType"),
'EnumType': Enum("javax.persistence.EnumType"),
'FetchType': Enum("javax.persistence.FetchType"),
'FlushModeType': Enum("javax.persistence.FlushModeType"),
'GenerationType': Enum("javax.persistence.GenerationType"),
'InheritanceType': Enum("javax.persistence.InheritanceType"),
'LockModeType': Enum("javax.persistence.LockModeType"),
'PersistenceContextType':
Enum("javax.persistence.PersistenceContextType"),
'TemporalType': Enum("javax.persistence.TemporalType"),
}

# constructor
def __init__(self, package, modifiers, name, superInterfaces = [],
annotations = [], innerClasses = [], properties = [],
methods = []):
RootFragment.__init__(self, packageName, modifiers, "enum",
name, superInterfaces, annotations, innerClasses, properties, methods)


?

I get

'CascadeType': Enum("javax.persistence.CascadeType"),

NameError: name 'Enum' is not defined

What's wrong with calling a constructor in a dict initializer? How do
I solve this?

well, within the class statement, it's not defined. So you can't call
Enum yet.

You have to create your dict somewhere else. You can either set it from
outside:

class Enum(RootFragment):
...

Enum._jpaTypes = { ... }


Or, do exactly the same thing, but within a class method:

class Enum(bla):
@classmethod
def contruct_jpatypes(cls):
cls.__jpaTypes = { ... }

Enum.construct_jpatypes()

THANKS for the quick help.
