Biber::Entry - Biber::Entry objects
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.
Recursively create related entry clones starting with an entry
Clone a Biber::Entry object and return a copy
Accepts optionally a key for the copy
Test for an empty object
Record the labelname information. This is special meta-information so we have a separate method for this Takes a hash ref with the information.
Retrieve the labelname information. This is special meta-information so we have a separate method for this Returns a hash ref with the information.
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.
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.
Record the labeltitle information. This is special meta-information so we have a separate method for this Takes a hash ref with the information.
Retrieve the labeltitle information. This is special meta-information so we have a separate method for this Returns a hash ref with the information.
Record the labeldate information. This is special meta-information so we have a separate method for this Takes a hash ref with the information.
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 a derived field for a Biber::Entry object, that is, a field which was not an actual bibliography field
Get a field for a Biber::Entry object
Uses // as fields can be null (end dates etc).
Set a field which is in the .bib data file
Get a field that was in the original data file
Delete a field in a Biber::Entry object
Delete an original data source data field in a Biber::Entry object
Check whether a field exists (even if null)
Check whether any parts of a date field exist when passed a datepart field name
Returns a sorted array of the fields which came from the data source
Returns the number of datafields
Returns a sorted array of the fields which were added during processing
Returns a sorted array of all field names, including ones
added during processing which are not necessarily fields
which came from the data file
Returns the number of fields
Check if a Biber::Entry object has a particular keyword in
in the KEYWORDS field.
Append a warning to a Biber::Entry object
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.
Recursively resolve XDATA fields in an entry
$entry->resolve_xdata($xdata_entry);
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 Biber::Entry object
