Constructor & Destructor Documentation

Declaration_reader::Declaration_reader (  Abstract_scope *    scope )

Create a general Declaration_reader. Names will be looked up in scope. Definition at line 14 of file decl_read.cc. References current_scope.

Declaration_reader::Declaration_reader (  Abstract_scope *    scope, Arg_vec *    args )

Create a Declaration_reader which collects function parameters. This one only accepts one call to parse_declarator(), not parse_declarator_list(). Parameters: scope  names will be looked up here args  parameters will be stored there Definition at line 29 of file decl_read.cc. References current_scope, and function_args.

Member Function Documentation

virtual void Declaration_reader::declare_variable (  Type    type, Ptree *    name, Ptree *    initializer, Ptree *    bitsize )  [pure virtual]

Implemented in Simple_declaration_reader, Typedef_name_reader, Typedef_declaration_reader, Function_declaration_reader, Ad_reader, and Name_decl_reader. Referenced by parse_declarator_internal().

Arg_vec* Declaration_reader::get_args (    )  const [inline]

Definition at line 39 of file decl_read.h. References Arg_vec, and function_args. Referenced by Simple_declaration_reader::declare_variable().

Abstract_scope* Declaration_reader::get_scope (    )  const [inline]

Definition at line 38 of file decl_read.h. Referenced by Typedef_declaration_reader::declare_variable(), and Simple_declaration_reader::declare_variable().

void Declaration_reader::parse_declarator (  Type    type, Ptree *    tree )

Read a declarator, and call declare_variable for it. Declarator syntax from standard: declarator: direct-declarator ptr-operator declarator direct-declarator: declarator-id direct-declarator ( parameter-declaration-clause ) cv-qualifier-seq opt exception-specification opt direct-declarator [ constant-expression opt ] ( declarator ) ptr-operator: cv-qualifier-seq opt & opt nested-name-specifier * cv-qualifier-seq opt "abstract-declarator" is essentially the same except that it has no "declarator-id". OpenC++ parses the above grammar and "flattens" it into one big list, including initializers and bitfields: declarator ::= identifier // sublist if qualified identifier | "*" : declarator | "&" : declarator | cv-qualifier : declarator | [ namepart... "::" "*" ] : declarator | declarator : postfix-expression* initializer? // declarator | postfix-expression* initializer? // abstract declarator postfix-expression ::= "(" : list-with-function-args : ")" ++ cv-qualifier-seq-opt | "[" : expression-with-array-size-or-nil : "]" initializer ::= "=" : expression | [ "(" : expression-list : ")" ] | ":" : expression // bitfield Definition at line 89 of file decl_read.cc.

Ptree * Declaration_reader::parse_declarator_get_name (  Ptree *    tree )
