PPI::Statement::Variable(3)          User Contributed Perl Documentation         PPI::Statement::Variable(3)



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.

TO DO
       - Write unit tests for this
