Clownfish::Symbol - Abstract base class for Clownfish symbols.


Clownfish::Symbol serves as an abstract parent class for entities which may live in the global namespace, such as classes, functions, methods, and variables.


    my $symbol = MySymbol->new(
        parcel      => 'Crustacean',             # default: special
        exposure    => 'parcel',                 # required
        class_name  => 'Crustacean::Lobster',    # default: undef
        class_cnick => undef,                    # default: special
        micro_sym   => 'average_lifespan',       # required
  • parcel - A Clownfish::Parcel, or a string that can be used to create/retrieve one. If not supplied, will be assigned to the default Parcel.

  • exposure - The scope in which the symbol is exposed. Must be 'public', 'parcel', 'private', or 'local'.

  • class_name - A optional class name, consisting of one or more components separated by "::". Each component must start with a capital letter, contain at least one lower-case letter, and consist entirely of the characters [A-Za-z0-9].

  • class_cnick - The C nickname associated with the supplied class name. If not supplied, will be derived if possible from class_name by extracting the last class name component.

  • micro_sym - The local identifier for the symbol.


get_parcel get_class_name get_class_cnick micro_sym


get_prefix get_Prefix get_PREFIX

Get a string prefix, delegating to parcel member var.

public parcel private local

    if    ( $sym->public ) { do_x() }
    elsif ( $sym->parcel ) { do_y() }

Indicate whether the symbol matches a given access level.


    do_stuff() if $sym->equals($other_sym);

Returns true if the symbols are "equal", false otherwise.


    # e.g. "Lobster_average_lifespan"
    print $symbol->short_sym;

Returns the C representation for the symbol minus the parcel's prefix.


    # e.g. "crust_Lobster_average_lifespan"
    print $symbol->full_sym;

Returns the fully qualified C representation for the symbol.
