= Compiler changes =
== CLASS_I and CLASS_C ==
=== Old ===
'''CLASS_I'''
*represents an uncompiled class.
*compiled class returns corresponding CLASS_C (if any)
*invariant: compiled_class.lace_class = Current
*cluster returns associated cluster

'''EXTERNAL_CLASS_I'''
*inherits from CLASS_I and CONF_CLASS_ASSEMBLY
*represents an uncompiled external class.
*assembly returns associated assembly

'''CLASS_C'''
*represents a compiled class.
*lace_class returns corresponding CLASS_I
*invariant: lace_class.compiled_class = Current

'''EXTERNAL_CLASS_C'''
*inherits from CLASS_C
*represents a compiled external class.

=== New ===
'''CONF_CLASS'''
*represents an uncompiled class as seen from the configuration system

'''CONF_CLASS_ASSEMBLY'''
*inherits from CONF_CLASS
*represents an external class

'''CONF_CLASS_PARTIAL'''
*inherits from CONF_CLASS
*represents a normal eiffel class that was generated out of multiple partial classes
*has a list of files from which it was generated

'''CLASS_I'''
*abstract
*represents an uncompiled class
*compiled class returns corresponding CLASS_C (if any)
*invariant: compiled_class.original_class = Current
*config_class returns CONFIG_CLASS
*group returns associated CONF_GROUP

'''EIFFEL_CLASS_I'''
*inherits from CLASS_I and CONF_CLASS
*represents a normal uncompiled eiffel class
*cluster returns associated CLUSTER_I

'''EXTERNAL_CLASS_I'''
*inherits from CLASS_I and CONF_CLASS_ASSEMBLY
*represents an external uncompiled class
*assembly returns associated ASSEMBLY_I

'''PARTIAL_EIFFEL_CLASS_I'''
*inherits from EIFFEL_CLASS_I and CONF_CLASS_PARTIAL
*represents a normal eiffel class that was automatically generated out of multiple partial classes

'''CLASS_C'''
*abstract
*represents a compiled class
*original_class returns CLASS_I for the original version of this class
*lace_class returns CLASS_I for the possible overriden version of this class that it was compiled from
*invariant: original_class.compiled_class = Current (compiled information is stored in original, not overriden class)
*is_eiffel_class_c is true if it's a normal eiffel class
*eiffel_class_c returns Current as EIFFEL_CLASS_C
*is_external_class is true if it's an external class
*external_class_c returns Current as EXTERNAL_CLASS_C

'''EIFFEL_CLASS_C'''
*inherits from CLASS_C
*represents a compiled normal eiffel class

'''EXTERNAL_CLASS_C'''
*inherits from CLASS_C
*represents a compiled external class

== clusters vs. groups ==
=== Old ===
'''CLUSER_I'''
*container for CLASS_I

'''ASSEMBLY_I'''
*inherits from CLUSTER_I
*represents an assembly
*container for EXTERNAL_CLASS_I

'''Recursive clusters'''
*For each subdirectory a CLUSTER_I was generated and the path was encoded into the name of the cluster

=== New ===
'''CONF_GROUP'''
*abstract container for CONF_CLASS
*class_by_name checks first in current group, then if a_dependencies is true also in dependencies that are enabled for a_platform and a_build

'''CONF_CLUSTER'''
*inherits from CONF_GROUP
*cluster
*can have a parent cluster
*can have multiple child clusters

'''CONF_OVERRIDE'''
*inherits from CONF_CLUSTER
*override cluster

'''CONF_LIBRARY'''
*inherits from CONF_GROUP
*library, has a library_target which can have CONF_CLUSTER, CONF_OVERRIDE, CONF_LIBRARY, CONF_PRECOMPILE, CONF_ASSEMBLY

'''CONF_PRECOMPILE'''
*inherits from CONF_LIBRARY
*represents a precompile

'''CONF_ASSEMBLY'''
*inherits from CONF_GROUP
*represents an assembly

'''Recursive clusters'''
*a recursive cluster is a normal cluster
*CONF_CLASS has path attribute that gives the path inside the cluster separated by /

== General ==
In most cases the use of CLUSTER_I can be replased by CONF_GROUP. For recursive clusters there is only one cluster and the information is in the classes in the path. The world is now a tree instead of a flat representation as before, for example we can have a library which can have clusters and another library ... For lots of things the easiest way to go through the information is to create a visitor. CONF_VISITOR visits every node, CONF_CONDITIONED_VISITOR only visits node that are enabled for the current build/platform.

'''Universe'''

The universe has now the complete configuration in conf_system, platform and build (only correctly set during compilation), the current target in target and the groups that are specified in the current target in groups.

Now there is a is_read_only query on a class.
