6 Biber::Entry - Biber::Entry objects
7 new
9 Initialize a Biber::Entry object
10 There are three types of field possible in an entry:
12 * data - These are fields which derive directly from or are themselves fields in the
14 data source. Things like YEAR, MONTH, DAY etc. are such fields which are
15 derived from, for example, the DATE field. They are part of the original
16 data implicitly, derived from a field.
17 * derived - These are fields, often meta-information like labelname, labelalpha etc.
18 which are more removed from the data fields.
19 The reason for this division is largely the entry cloning required for the related entry and
21 inheritance features. When we clone an entry or copy some fields from one entry to another
22 we generally don't want the "derived" category as such derived meta-fields will often need
23 to be re-created or ignored so we need to know which are the actual "data" fields to
24 copy/clone.
25 relclone
27 Recursively create related entry clones starting with an entry
28 clone
30 Clone a Biber::Entry object and return a copy
31 Accepts optionally a key for the copy
32 notnull
34 Test for an empty object
35 add_xdata_ref
37 Add an XDATA reference to the entry
38 Reference can be simply to an entire XDATA entry or a particular field+position in field
39 Record reference and target positions so that the XDATA marker can be removed as otherwise
40 it would break further parsing
41 get_xdata_refs
43 Get the XDATA references
44 get_xdata_ref
46 Get a specific XDATA reference
47 is_xdata_resolved
49 Checks if an XDATA reference was resolved. Returns false also for
50 "no such reference".
51 set_labelname_info
53 Record the labelname information. This is special
54 meta-information so we have a separate method for this
55 Takes a hash ref with the information.
56 get_labelname_info
58 Retrieve the labelname information. This is special
59 meta-information so we have a separate method for this
60 Returns a hash ref with the information.
61 set_labelnamefh_info
63 Record the fullhash labelname information. This is special
64 meta-information so we have a separate method for this
65 Takes a hash ref with the information.
66 get_labelnamefh_info
68 Retrieve the fullhash labelname information. This is special
69 meta-information so we have a separate method for this
70 Returns a hash ref with the information.
71 set_labeltitle_info
73 Record the labeltitle information. This is special
74 meta-information so we have a separate method for this
75 Takes a hash ref with the information.
76 get_labeltitle_info
78 Retrieve the labeltitle information. This is special
79 meta-information so we have a separate method for this
80 Returns a hash ref with the information.
81 set_labeldate_info
83 Record the labeldate information. This is special
84 meta-information so we have a separate method for this
85 Takes a hash ref with the information.
86 get_labeldate_info
88 Retrieve the labeldate information. This is special
89 meta-information so we have a separate method for this
90 Returns a hash ref with the information.
91 set_field
93 Set a derived field for a Biber::Entry object, that is, a field
94 which was not an actual bibliography field
95 get_field
97 Get a field for a Biber::Entry object
98 Uses // as fields can be null (end dates etc).
99 set_datafield
101 Set a field which is in the .bib data file
102 get_datafield
104 Get a field that was in the original data file
105 del_field
107 Delete a field in a Biber::Entry object
108 del_datafield
110 Delete an original data source data field in a Biber::Entry object
111 field_exists
113 Check whether a field exists (even if null)
114 date_fields_exist
116 Check whether any parts of a date field exist when passed a datepart field name
117 delete_date_fields
119 Delete all parts of a date field when passed any datepart field name
120 datafields
122 Returns a sorted array of the fields which came from the data source
123 count_datafields
125 Returns the number of datafields
126 derivedfields
128 Returns a sorted array of the fields which were added during processing
129 fields
131 Returns a sorted array of all field names, including ones
132 added during processing which are not necessarily fields
133 which came from the data file
134 count_fields
136 Returns the number of fields
137 has_keyword
139 Check if a Biber::Entry object has a particular keyword in
140 in the KEYWORDS field.
141 add_warning
143 Append a warning to a Biber::Entry object
144 set_inherit_from
146 Inherit fields from first child entry
147 $entry->set_inherit_from($firstchild);
149 Takes a second Biber::Entry object as argument
151 The purpose here is to inherit fields so that sorting/labelling defaults
153 can be generated for set parents from the first child set member data, unless
154 the set parent itself already has some fields set that will do this. Set
155 parents only have certain fields output in the .bbl and those that output but
156 are not used in sorting/labelling data generation should not be inherited.
157 resolve_xdata
159 Recursively resolve XDATA in an entry. Sets a flag in the XDATA metadata to
160 say if the reference was successfully resolved.
161 $entry->resolve_xdata($xdata);
163 inherit_from
165 Inherit fields from parent entry (as indicated by the crossref field)
166 $entry->inherit_from($parententry);
168 Takes a second Biber::Entry object as argument
170 Uses the crossref inheritance specifications from the .bcf
171 dump
173 Dump Biber::Entry object
