Biber::Entry(3pm) User Contributed Perl Documentation Biber::Entry(3pm) NAME Biber::Entry - Biber::Entry objects new Initialize a Biber::Entry object There are three types of field possible in an entry: * data - These are fields which derive directly from or are themselves fields in the data source. Things like YEAR, MONTH, DAY etc. are such fields which are derived from, for example, the DATE field. They are part of the original data implicitly, derived from a field. * derived - These are fields, often meta-information like labelname, labelalpha etc. which are more removed from the data fields. The reason for this division is largely the entry cloning required for the related entry and inheritance features. When we clone an entry or copy some fields from one entry to another we generally don't want the "derived" category as such derived meta-fields will often need to be re-created or ignored so we need to know which are the actual "data" fields to copy/clone. relclone Recursively create related entry clones starting with an entry clone Clone a Biber::Entry object and return a copy Accepts optionally a key for the copy notnull Test for an empty object add_xdata_ref Add an XDATA reference to the entry Reference can be simply to an entire XDATA entry or a particular field+position in field Record reference and target positions so that the XDATA marker can be removed as otherwise it would break further parsing get_xdata_refs Get the XDATA references get_xdata_ref Get a specific XDATA reference is_xdata_resolved Checks if an XDATA reference was resolved. Returns false also for "no such reference". set_labelname_info Record the labelname information. This is special meta-information so we have a separate method for this Takes a hash ref with the information. get_labelname_info Retrieve the labelname information. This is special meta-information so we have a separate method for this Returns a hash ref with the information. set_labelnamefh_info Record the fullhash labelname information. This is special meta-information so we have a separate method for this Takes a hash ref with the information. get_labelnamefh_info Retrieve the fullhash labelname information. This is special meta-information so we have a separate method for this Returns a hash ref with the information. set_labeltitle_info Record the labeltitle information. This is special meta-information so we have a separate method for this Takes a hash ref with the information. get_labeltitle_info Retrieve the labeltitle information. This is special meta-information so we have a separate method for this Returns a hash ref with the information. set_labeldate_info Record the labeldate information. This is special meta-information so we have a separate method for this Takes a hash ref with the information. get_labeldate_info Retrieve the labeldate information. This is special meta-information so we have a separate method for this Returns a hash ref with the information. set_field Set a derived field for a Biber::Entry object, that is, a field which was not an actual bibliography field get_field Get a field for a Biber::Entry object Uses // as fields can be null (end dates etc). set_datafield Set a field which is in the .bib data file get_datafield Get a field that was in the original data file del_field Delete a field in a Biber::Entry object del_datafield Delete an original data source data field in a Biber::Entry object field_exists Check whether a field exists (even if null) date_fields_exist Check whether any parts of a date field exist when passed a datepart field name delete_date_fields Delete all parts of a date field when passed any datepart field name datafields Returns a sorted array of the fields which came from the data source count_datafields Returns the number of datafields derivedfields Returns a sorted array of the fields which were added during processing fields Returns a sorted array of all field names, including ones added during processing which are not necessarily fields which came from the data file count_fields Returns the number of fields has_keyword Check if a Biber::Entry object has a particular keyword in in the KEYWORDS field. add_warning Append a warning to a Biber::Entry object set_inherit_from Inherit fields from first child entry $entry->set_inherit_from($firstchild); Takes a second Biber::Entry object as argument The purpose here is to inherit fields so that sorting/labelling defaults can be generated for set parents from the first child set member data, unless the set parent itself already has some fields set that will do this. Set parents only have certain fields output in the .bbl and those that output but are not used in sorting/labelling data generation should not be inherited. resolve_xdata Recursively resolve XDATA in an entry. Sets a flag in the XDATA metadata to say if the reference was successfully resolved. $entry->resolve_xdata($xdata); inherit_from Inherit fields from parent entry (as indicated by the crossref field) $entry->inherit_from($parententry); Takes a second Biber::Entry object as argument Uses the crossref inheritance specifications from the .bcf dump Dump Biber::Entry object AUTHORS Philip Kime "" BUGS Please report any bugs or feature requests on our Github tracker at .
