Class::Fields::Attribs(3)

NAME
  Class::Fields::Attribs - Attribute constants for use with data members

SYNOPSIS
  # Export the attribute constants
  use Class::Fields::Attribs;

DESCRIPTION
Simply exports a set of constants used for low level work on data members. Each constant is a bitmask used to represent the type of a data member (as in Public, Private, etc...).

The exported attributes are:

PUBLIC
PRIVATE
PROTECTED
INHERITED
    Each of these constants is a bitmask representing a possible setting of a field attribute. They can be combined by using a bitwise OR and attributes can be checked for using a bitwise AND. For example:

        # Indicate a piece of data which is both public and inherited.
        $attrib = PUBLIC | INHERITED;

        # Check to see if an attribute is protected.
        print "Protected" if $attrib & PROTECTED;

    It is rare that one has to use these constants and it is generally better to use the functions provided by Class::Fields.
