Constructor & Destructor Documentation

Symbol_table::Symbol_table (    )

Create new, empty symbol table. Generally, you should use Symbol_table::get_instance() instead of creating new symbol tables. Definition at line 21 of file symbol_table.cc.

Symbol_table::~Symbol_table (    )  [virtual]

Definition at line 27 of file symbol_table.cc.

Member Function Documentation

void Symbol_table::add_symbol (  std::string    name, std::string::size_type    base_len, Symbol *    sym )

Add a symbol. Throws exception on error. Definition at line 34 of file symbol_table.cc. References compile_error(), content, Symbol::is_tagged(), and Symbol::set_name(). Referenced by Namespace_scope::add_symbol(), Class_scope::add_symbol(), and Block_scope::add_symbol().

Sym_it Symbol_table::begin (    )  const [inline]

Definition at line 110 of file symbol_table.h. References content, and Sym_it. Referenced by main().

void Symbol_table::clear (    )

Definition at line 121 of file symbol_table.cc. References content, and content_type.

void Symbol_table::dump (  std::ostream &    out )

Dump symbol table to /out/. Definition at line 95 of file symbol_table.cc. References content. Referenced by main().

Sym_it Symbol_table::end (    )  const [inline]

Definition at line 111 of file symbol_table.h. References content, and Sym_it. Referenced by main().

Symbol_table& Symbol_table::get_instance (    )  [inline, static]

Definition at line 108 of file symbol_table.h. Referenced by Namespace_scope::add_symbol(), Class_scope::add_symbol(), Block_scope::add_symbol(), Typedef_declaration_reader::declare_variable(), Type::get_type_symbol(), Class_symbol::lookup_helper(), Namespace_scope::lookup_here(), Block_scope::lookup_here(), main(), and Class_symbol::start_definition().

Symbol_pair Symbol_table::get_symbol (  std::string    name )  const

Fetch a symbol. Returns the symbol table entry. Definition at line 82 of file symbol_table.cc. References content. Referenced by Type::get_type_symbol(), Namespace_scope::lookup_here(), and Block_scope::lookup_here().

bool Symbol_table::has_dump_flag (  char    c )  [static]

Definition at line 109 of file symbol_table.cc. References dump_flags. Referenced by Variable_symbol::dump(), Function_signature::dump(), main(), print_annotated_tree(), process(), and Program_from_fd::Program_from_fd().

void Symbol_table::set_peer (  Symbol *    orig, Symbol *    faelschung )

Set "peer" of a symbol. This is used for the construction "typedef class A {} B;". In that case, "B" becomes an alternate name for A. Hence, the "untag" slot of the symbol B contains the typedef, the "tag" slot becomes the base type. Definition at line 71 of file symbol_table.cc. References content, Symbol::get_name(), and Symbol::is_tagged(). Referenced by Typedef_declaration_reader::declare_variable(), and Class_symbol::start_definition().
