-=head1 NAME
-
-RT::Shredder::Constants - RT::Shredder constants that is used to mark state of RT objects.
-
-=head1 DESCRIPTION
-
-This module exports two group of bit constants.
-First group is group of flags which are used to clarify dependecies between objects, and
-second group is states of RT objects in Shredder cache.
-
-=head1 FLAGS
-
-=head2 DEPENDS_ON
-
-Targets that has such dependency flag set should be wiped out with base object.
-
-=head2 WIPE_AFTER
-
-If dependency has such flag then target object would be wiped only
-after base object. You should mark dependencies with this flag
-if two objects depends on each other, for example Group and Principal
-have such relationship, this mean Group depends on Principal record and
-that Principal record depends on the same Group record. Other examples:
-User and Principal, User and its ACL equivalence group.
-
-=head2 VARIABLE
-
-This flag is used to mark dependencies that can be resolved with changing
-value in target object. For example ticket can be created by user we can
-change this reference when we delete user.
-
-=head2 RELATES
-
-This flag is used to validate relationships integrity. Base object
-is valid only when all target objects which are marked with this flags
-exist.
-

-use constant {
- DEPENDS_ON => 0x000001,
- WIPE_AFTER => 0x000010,
- RELATES => 0x000100,
- VARIABLE => 0x001000,
-};
-
-=head1 STATES
-
-=head2 ON_STACK
-
-Default state of object in Shredder cache that means that object is
-loaded and placed into cache.
-
-=head2 WIPED
-
-Objects with this state are not exist any more in DB, but perl
-object is still in memory. This state is used to be shure that
-delete query is called once.
-
-=head2 VALID
-
-Object is marked with this state only when its relationships
-are valid.
-
-=head2 INVALID
