bool DCClass::add_field | ( | DCField * | field | ) |
Adds the newly-allocated field to the class.
The class becomes the owner of the pointer and will delete it when it destructs. Returns true if the field is successfully added, or false if there was a name conflict or some other problem.

void DCClass::add_parent | ( | DCClass * | parent | ) |
Adds a new parent to the inheritance hierarchy of the class.
This is normally called only during parsing.

Empties the list of inherited fields for the class, so that it may be rebuilt.
This is normally only called by DCFile::rebuild_inherited_fields().

DCField * DCClass::get_field | ( | int | n | ) | const |
Returns the nth field in the class.
This is not necessarily the field with index n; this is the nth field defined in the class directly, ignoring inheritance.
Definition at line 180 of file dcClass.cxx.
Referenced by get_inherited_field().
DCField * DCClass::get_field_by_index | ( | int | index_number | ) | const |
Returns a pointer to the DCField that has the indicated index number.
If the numbered field is not found in the current class, the parent classes will be searched, so the value returned may not actually be a field within this class. Returns NULL if there is no such field defined.
Definition at line 227 of file dcClass.cxx.
DCField * DCClass::get_field_by_name | ( | const std::string & | name | ) | const |
Returns a pointer to the DCField that shares the indicated name.
If the named field is not found in the current class, the parent classes will be searched, so the value returned may not actually be a field within this class. Returns NULL if there is no such field defined.
Definition at line 200 of file dcClass.cxx.
DCField * DCClass::get_inherited_field | ( | int | n | ) | const |
Returns the nth field field in the class and all of its ancestors.
This *used* to be the same thing as get_field_by_index(), back when the fields were numbered sequentially within a class's inheritance hierarchy. Now that fields have a globally unique index number, this is no longer true.

This is set for classes that are generated by the parser as placeholder for missing classes, as when reading a partial file; it should not occur in a normal valid dc file.
