NAME

PPI::Token::Symbol - A token class for variables and other symbols

INHERITANCE

  PPI::Token::Symbol
  isa PPI::Token
      isa PPI::Element

DESCRIPTION

The "PPI::Token::Symbol" class is used to cover all tokens that represent variables and other things that start with a sigil.

METHODS

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.

canonical

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.

symbol

The "symbol" method returns the 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.

raw_type

The "raw_type" method returns the apparent type of the symbol in the form of its sigil.

Returns the sigil as a string.

symbol_type

The "symbol_type" method returns the actual type of the symbol in the form of its sigil.

Returns the sigil as a string.

SUPPORT

See the support section in the main module.
