Base Library: Class Creation and Initialization
This library cluster has 39 classes.
ECF: base.ecf
Classes for the following:
- Creating and initializing instances of a class.
- Factory indirection, i.e. factories for creating factories.
- Managing cross-platform bridge initialization
- Managing Precursor calls to avoid repeats
- Managing creation and initialization of singleton objects
- Managing creation of "lazy attributes"

EL_FACTORY_ROUTINES_IMP
Routines for creating instances of factory classes. Accessible via EL_MODULE_FACTORY.
EL_FACTORY_TYPE_ID_TABLE
Cache table of dynamic type id for a factory type derived from a composite key containing a general factory type and a type conforming to generic argument of factory type.

EL_INITIALIZEABLE
Interface to object with initialized state

EL_LAZY_ATTRIBUTE
Detachable object attribute that is created only when needed

EL_INITIALIZED_OBJECT_FACTORY
EL_OBJECT_FACTORY [G] that can create initialized objects using factory conforming to EL_FACTORY [G]

EL_MAKEABLE_FACTORY
A factory cell to create objects conforming to EL_MAKEABLE
Further Information

EL_MAKEABLE_FROM_STRING_FACTORY
A factory cell to create objects conforming to EL_MAKEABLE_FROM_STRING [STRING_GENERAL]
Further Information

EL_MAKEABLE_OBJECT_FACTORY
Factory to create objects conforming to EL_MAKEABLE

EL_MAKEABLE_TO_SIZE_FACTORY
A factory cell to create objects conforming to EL_MAKEABLE_TO_SIZE
EL_OBJECT_FACTORY
Factory for instances of Eiffel classes conforming to parameter G
Tuple arguments act as type manifests with each type A, B, C.. conforming to G. A contract ensures all types conform. Typically you would create the tuple like this:
Types: TUPLE [A, B, C ..]
once
create Result
end
