#   Constants: Implementation
#
#   The object is implemented as a blessed arrayref.  The constants below are used as indexes.
#
#   SCOPE - The new scope <SymbolString>.
#   LINE_NUMBER - The line number of the change.
#
use NaturalDocs::DefineMembers 'SCOPE', 'LINE_NUMBER';
# Dependency: New() depends on the order of these constants as well as that there is no inherited members.


#
#   Function: New
#
#   Creates and returns a new object.
#
#   Parameters:
#
#       scope - The <SymbolString> the scope was changed to.
#       lineNumber - What line it occurred on.
#
sub New #(scope, lineNumber)

    # Dependency: This depends on the order of the parameters matching the constants, and that there are no inherited
    # members.
