PPI::Token::Symbol - A token class for variables and other symbols
PPI::Token::Symbol isa PPI::Token isa PPI::Element
The PPI::Token::Symbol
class is used to cover all tokens that represent
variables and other things that start with a sigil.
This class has several methods beyond what is provided by its PPI::Token and PPI::Element parent classes.
Most methods are provided to help work out what the object is actually pointing at, rather than what it might appear to be pointing at.
The canonical
method returns a normalized, canonical version of the
symbol.
For example, it converts $ ::foo'bar::baz
to $main::foo::bar::baz
.
This does not fully resolve the symbol, but merely removes syntax variations.
The symbol
method returns the ACTUAL symbol this token refers to.
A token of $foo
might actually be referring to @foo
, if it is found
in the form $foo[1]
.
This method attempts to resolve these issues to determine the actual symbol.
Returns the symbol as a string.
The raw_type
method returns the apparent type of the symbol in the
form of its sigil.
Returns the sigil as a string.
The symbol_type
method returns the actual type of the symbol in the
form of its sigil.
Returns the sigil as a string.
