| 31 // were loaded into a single process. | |
| 32 // | |
| 33 // This is a basic concrete implementation of CodeModules. It cannot be | |
| 34 // instantiated directly, only based on other objects that implement | |
| 35 // the CodeModules interface. It exists to provide a CodeModules | |
| 36 // implementation a place to store information when the life of the original | |
| 37 // object (such as a MinidumpModuleList) cannot be guaranteed. | |
