12
14 The "PPI::Token::Symbol" class is used to cover all tokens that
15 represent variables and other things that start with a sigil.
16
18 This class has several methods beyond what is provided by its
19 PPI::Token and PPI::Element parent classes.
20
21 Most methods are provided to help work out what the object is actually
22 pointing at, rather than what it might appear to be pointing at.
23
24 canonical
25 The "canonical" method returns a normalized, canonical version of the
26 symbol.
27
28 For example, it converts "$ ::foo'bar::baz" to $main::foo::bar::baz.
29
30 This does not fully resolve the symbol, but merely removes syntax
31 variations.
32
33 symbol
34 The "symbol" method returns the ACTUAL symbol this token refers to.
35
36 A token of $foo might actually be referring to @foo, if it is found in
37 the form $foo[1].
38
39 This method attempts to resolve these issues to determine the actual
40 symbol.
41
42 Returns the symbol as a string.
43
44 raw_type
45 The "raw_type" method returns the apparent type of the symbol in the
46 form of its sigil.
47
48 Returns the sigil as a string.
49
50 symbol_type
51 The "symbol_type" method returns the actual type of the symbol in the
52 form of its sigil.
53
54 Returns the sigil as a string.
