NAME

6       PPI::Token::BOM - Tokens representing Unicode byte order marks
7

INHERITANCE

9         PPI::Token::BOM
10         isa PPI::Token
11             isa PPI::Element
12

DESCRIPTION

14       This is a special token in that it can only occur at the beginning of
15       documents.  If a BOM byte mark occurs elsewhere in a file, it should be
16       treated as PPI::Token::Whitespace.  We recognize the byte order marks
17       identified at this URL: <http://www.unicode.org/faq/utf_bom.html#BOM>
18
19           UTF-32, big-endian     00 00 FE FF
20           UTF-32, little-endian  FF FE 00 00
21           UTF-16, big-endian     FE FF
22           UTF-16, little-endian  FF FE
23           UTF-8                  EF BB BF
24
25       Note that as of this writing, PPI only has support for UTF-8 (namely,
26       in POD and strings) and no support for UTF-16 or UTF-32.  We support
27       the BOMs of the latter two for completeness only.
28
29       The BOM is considered non-significant, like white space.

METHODS

32       There are no additional methods beyond those provided by the parent
33       PPI::Token and PPI::Element classes.
