#
#   Constants: Members
#
#   The class is implemented as a blessed arrayref.  The following constants are its members.
#
#       SYMBOL  - The target <SymbolString>.
#       FILE        - The <FileName> the target is defined in.
#       TYPE       - The target <TopicType>.
#       PROTOTYPE - The target's prototype, or undef if none.
#       SUMMARY    - The target's summary, or undef if none.
#

# DEPENDENCY: New() depends on the order of these constants.  If they change, New() has to be updated.
use constant SYMBOL => 0;
use constant FILE => 1;
use constant TYPE => 2;
use constant PROTOTYPE => 3;
