ppi::statement::null
PPI::Statement::Null(3) User Contributed Perl Documentation PPI::Statement::Null(3)
NAME
PPI::Statement::Null - A useless null statement
SYNOPSIS
my $foo = 1;
; # <-- Null statement
my $bar = 1;
INHERITANCE
PPI::Statement::Null
isa PPI::Statement
isa PPI::Node
isa PPI::Element
DESCRIPTION
"PPI::Statement::Null" is a utility class designed to handle situations where PPI encounters a naked statement separator.
Although strictly speaking, the semicolon is a statement separator and not a statement terminator, PPI considers a semicolon to be a
statement terminator under most circumstances.
In any case, the null statement has no purpose, and can be safely deleted with no ill effect.
METHODS
"PPI::Statement::Null" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element.
SUPPORT
See the support section in the main module.
