# Constants: Members

# The class is implemented as a blessed arrayref. The following constants are its members.
|
|
#
|
|
# SYMBOLS - An existence hashref of the <SymbolStrings> it defines.
|
|
# REFERENCES - An existence hashref of the <ReferenceStrings> in the file.
|
|
#
|
|
|
|
# DEPENDENCY: New() depends on the order of these constants. If they change, New() has to be updated.
