6 PPI::Statement::Variable - Variable declaration statements

9 # All of the following are variable declarations
10 my $foo = 1;
11 my ($foo, $bar) = (1, 2);
12 our $foo = 1;
13 local $foo;
14 local $foo = 1;
15 LABEL: my $foo = 1;

21 isa PPI::Node
22 isa PPI::Element
23
25 The main intent of the "PPI::Statement::Variable" class is to describe
26 simple statements that explicitly declare new local or global
27 variables.
28
29 Note that this does not make it exclusively the only place where
30 variables are defined, and later on you should expect that the
31 "variables" method will migrate deeper down the tree to either
32 PPI::Statement or PPI::Node to recognise this fact, but for now it
33 stays here.
34
36 type
37 The "type" method checks and returns the declaration type of the
38 statement, which will be one of 'my', 'local', 'our', or 'state'.
39
40 Returns a string of the type, or "undef" if the type cannot be detected
41 (which is probably a bug).
42
43 variables
44 As for several other PDOM Element types that can declare variables, the
45 "variables" method returns a list of the canonical forms of the
46 variables defined by the statement.
47
48 Returns a list of the canonical string forms of variables, or the null
49 list if it is unable to find any variables.
50
51 symbols
52 Returns a list of the variables defined by the statement, as
53 PPI::Token::Symbols.
