NAME

       Biber::Section - Biber::Section objects

   new
           Initialize a Biber::Section object

   reset_caches
           Reset section caches which need it

   set_keytods
         Save information about citekey->datasource name mapping. Used for error reporting.

   get_keytods
         Get information about citekey->datasource name mapping. Used for error reporting.

   has_badcasekey
           Returns a value to say if we've seen a key differing only in case before
           <previouskey>  - we've seen a differently cased variant of this key so we can warn about this
           undef  - Not seen this key at all in any case variant before

   add_related
           Record that a key is used as a related entry

   is_related
           Check if a key is used as a related entry key

   keytorelclone
           Record a key<->clone key mapping.

   get_keytorelclone
           Fetch a related entry clone key, given a cite key

   get_relclonetokey
           Fetch a related entry key, given a clone key

   has_keytorelclone
           Return boolean saying if a cite key has a related entry clone in the current section

   has_relclonetokey
           Return boolean saying if a related clone key has a citekey in the current section

   add_everykey
           Adds a datasource key to the section list of all datasource keys

   del_everykeys
         Delete everykey cache. For use in tests.

   has_everykey
           Returns a boolean to say if we've seen a key in any datasource for this section.
           This used to be an array ref which was checked using first() and it
           was twenty times slower.

   set_allkeys
           Sets flag to say citekey '*' occurred in citekeys
           We allow setting it to false too because it's useful in tests

   is_allkeys
           Checks flag which says citekey '*' occurred in citekeys

   bibentry
           Returns a Biber::Entry object for the given citation key
           Understands citekey aliases

   bibentries
           Return Biber::Entries object for this section

   del_bibentries
           Delete all Biber::Entry objects from the Biber::Section object

   set_citekeys
           Sets the citekeys in a Biber::Section object

   set_orig_order_citekeys
           Sets the original order of citekeys in a Biber::Section object

   get_citekeys
           Gets the citekeys of a Biber::Section object
           Returns a normal array

   get_static_citekeys
           Gets the citekeys of a Biber::Section object
           excluding dynamic set entry keys
           Returns a normal array

   has_cited_citekey
           Returns true when $key was one of the actually cited keys in the section

   add_undef_citekey
           Adds a citekey to the Biber::Section object as an undefined
           key. This allows us to output this information to the .bbl and
           so biblatex can do better reporting to external utils like latexmk

   get_undef_citekeys
           Gets the list of undefined citekeys of a Biber::Section object
           Returns a normal array

   get_orig_order_citekeys
           Gets the citekeys of a Biber::Section object in their original order
           This is just to ensure we have a method that will return this, just in
           case we mess about with the order at some point. This is needed by
           citeorder sorting.

   has_citekey
           Returns true when $key is in the Biber::Section object
           Understands key alaises

   del_citekey
           Deletes a citekey from a Biber::Section object

   del_citekeys
           Deletes all citekeys from a Biber::Section object

   add_citekeys
           Adds citekeys to the Biber::Section object

   set_citekey_alias
           Set citekey alias information

   get_citekey_alias
           Get citekey alias information

   del_citekey_alias
           Delete citekey alias

   get_citekey_aliases
           Get a list of all citekey aliases for the section

   set_labelcache_v
           Sets the variable label disambiguation cache for a field

   get_labelcache_v
           Gets the variable label disambiguation cache for a field

   set_labelcache_l
           Sets the list label disambiguation cache for a field

   get_labelcache_l
           Gets the list label disambiguation cache for a field

   is_dynamic_set
           Test if a key is a dynamic set

   set_dynamic_set
           Record a mapping of dynamic key to member keys

   get_dynamic_set
           Retrieve member keys for a dynamic set key
           Check that reference returning anything to stop spurious warnings
           about empty dereference in return.

   dynamic_set_keys
           Retrieve all dynamic set keys

   has_dynamic_sets
           Returns true of false depending on whether the section has any dynamic set keys

   add_datasource
           Adds a data source to a section

   set_datasources
           Sets the data sources for a section

   get_datasources
           Gets an array of data sources for this section

   number
           Gets the section number of a Biber::Section object
