49 package RT::Shredder::Constants;
51 use base qw(Exporter);
55 RT::Shredder::Constants - RT::Shredder constants that is used to mark state of RT objects.
59 This module exports two group of bit constants.
60 First group is group of flags which are used to clarify dependecies between objects, and
61 second group is states of RT objects in Shredder cache.
67 Targets that has such dependency flag set should be wiped out with base object.
71 If dependency has such flag then target object would be wiped only
72 after base object. You should mark dependencies with this flag
73 if two objects depends on each other, for example Group and Principal
74 have such relationship, this mean Group depends on Principal record and
75 that Principal record depends on the same Group record. Other examples:
76 User and Principal, User and its ACL equivalence group.
80 This flag is used to mark dependencies that can be resolved with changing
81 value in target object. For example ticket can be created by user we can
82 change this reference when we delete user.
86 This flag is used to validate relationships integrity. Base object
87 is valid only when all target objects which are marked with this flags
93 DEPENDS_ON => 0x000001,
94 WIPE_AFTER => 0x000010,
103 Default state of object in Shredder cache that means that object is
104 loaded and placed into cache.
108 Objects with this state are not exist any more in DB, but perl
109 object is still in memory. This state is used to be shure that
110 delete query is called once.
114 Object is marked with this state only when its relationships
123 IN_WIPING => 0x00001,
