annotate libinterp/parse-tree/oct-parse.in.yy @ 18287:69990d5edcc2
Allow to parse external methods declaration in classdef files.
* libinterp/parse-tree/parser.h
(octave_base_parser::start_classdef_external_method,
octave_base_parser::finish_classdef_external_method): New methods.
* libinterp/parse-tree/oct-parse.in.yy
(octave_base_parser::start_classdef_external_method,
octave_base_parser::finish_classdef_external_method): Likewise.
(%destructor): Add missing directives for classdef-related types.
(method, method_decl, method_decl1): New nonterminal rules.
(methods_list): Use "method" on terminal.
* libinterp/octave-value/ov-classdef.cc
(cdef_package::cdef_package_rep::meta_subsref): When searching for
package methods, only issue an error when error_state is not set.
