.SH "NAME"
BibTeX::Parser::Entry \- Contains a single entry of a BibTeX document.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
This class ist a wrapper for a single BibTeX entry. It is usually created
by a BibTeX::Parser.

.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.SS "new"
.IX Subsection "new"
Create new entry.
.SS "parse_ok"
.IX Subsection "parse_ok"
If the entry was correctly parsed, this method returns a true value, false otherwise.
.SS "error"
.IX Subsection "error"
Return the error message, if the entry could not be parsed or undef otherwise.
.SS "type"
.IX Subsection "type"
Get or set the type of the entry, eg. '\s-1ARTICLE\s0' or '\s-1BOOK\s0'. Return value is 
always uppercase.
.SS "key"
.IX Subsection "key"
Get or set the reference key of the entry.
.ie n .SS "field($name [, $value])"
.el .SS "field($name [, \f(CW$value\fP])"
.IX Subsection "field($name [, $value])"
Get or set the contents of a field. The first parameter is the name of the
field, the second (optional) value is the new value.
.SS "cleaned_field($name)"
.IX Subsection "cleaned_field($name)"
Retrieve the contents of a field in a format that is cleaned of TeX markup.
.SS "cleaned_author"
.IX Subsection "cleaned_author"
Get an array of BibTeX::Parser::Author objects for the authors of this
entry. Each name has been cleaned of accents and braces.
.SS "cleaned_editor"
.IX Subsection "cleaned_editor"
Get an array of BibTeX::Parser::Author objects for the editors of this
entry. Each name has been cleaned of accents and braces.
.SS "author([@authors])"
.IX Subsection "author([@authors])"
Get or set the authors. Returns an array of BibTeX::Author 
objects. The parameters can either be BibTeX::Author objects
or strings.
.PP
Note: You can also change the authors with \f(CW$entry\fR\->field('author', \f(CW$authors_string\fR)
.SS "editor([@editors])"
.IX Subsection "editor([@editors])"
Get or set the editors. Returns an array of BibTeX::Author 
objects. The parameters can either be BibTeX::Author objects
or strings.
.PP
Note: You can also change the authors with \f(CW$entry\fR\->field('editor', \f(CW$editors_string\fR)
.SS "fieldlist ()"
.IX Subsection "fieldlist ()"
Returns a list of all the fields used in this entry.
.SS "has($fieldname)"
.IX Subsection "has($fieldname)"
Returns a true value if this entry has a value for \f(CW$fieldname\fR.
.SS "pre ()"
.IX Subsection "pre ()"
Return the text in BibTeX file before the entry
.SS "raw_bibtex ()"
.IX Subsection "raw_bibtex ()"
Return raw BibTeX entry (if available).
.SS "to_string ([options])"
.IX Subsection "to_string ([options])"
Returns a text of the BibTeX entry in BibTeX format.  Options are
a hash.
.ie n .IP """canonize_names""" 4
.el .IP "\f(CWcanonize_names\fR" 4
.IX Item "canonize_names"
If true (the default), authors' and editors' 
names are translated into canonical bibtex form.  The command 
\&\f(CW\*(C`$entry\->to_string(canonize_names=>0)\*(C'\fR overrides this behavior.
.ie n .IP """field_capitalization""" 4
.el .IP "\f(CWfield_capitalization\fR" 4
.IX Item "field_capitalization"
Capitalization of the field names.  
Can take values 'Uppercase', 'Lowercase' (the default) or 'Titlecase'
.ie n .IP """print_pre""" 4
.el .IP "\f(CWprint_pre\fR" 4
.IX Item "print_pre"
False by default.  If true, the text in the Bib file before the
entry is printed.  Note that at present we assume the text 
before the entry \s-1NEVER\s0 has the @ symbol inside
.ie n .IP """type_capitalization""" 4
.el .IP "\f(CWtype_capitalization\fR" 4
.IX Item "type_capitalization"
Capitalization of the type names.  
Can take values 'Uppercase' (the default), 'Lowercase' or 'Titlecase'
