PPI::Statement::Variable(3pm) User Contributed Perl Documentation PPI::Statement::Variable(3pm)NAME
PPI::Statement::Variable - Variable declaration statements
SYNOPSIS
# All of the following are variable declarations
my $foo = 1;
my ($foo, $bar) = (1, 2);
our $foo = 1;
local $foo;
local $foo = 1;
LABEL: my $foo = 1;
INHERITANCE
PPI::Statement::Variable
isa PPI::Statement::Expression
isa PPI::Statement
isa PPI::Node
isa PPI::Element
DESCRIPTION
The main intent of the "PPI::Statement::Variable" class is to describe simple statements that explicitly declare new local or global
variables.
Note that this does not make it exclusively the only place where variables are defined, and later on you should expect that the "variables"
method will migrate deeper down the tree to either PPI::Statement or PPI::Node to recognise this fact, but for now it stays here.
METHODS
type
The "type" method checks and returns the declaration type of the statement, which will be one of 'my', 'local', 'our', or 'state'.
Returns a string of the type, or "undef" if the type cannot be detected (which is probably a bug).
variables
As for several other PDOM Element types that can declare variables, the "variables" method returns a list of the canonical forms of the
variables defined by the statement.
Returns a list of the canonical string forms of variables, or the null list if it is unable to find any variables.
symbols
Returns a list of the variables defined by the statement, as PPI::Token::Symbols.
