CallFrame Properties | 
The CallFrame type exposes the following members.
| Name | Description | |
|---|---|---|
| CallFrameId | 
            Call frame identifier. This identifier is only valid while the virtual machine is paused.
              | |
| CanBeRestarted | 
            Valid only while the VM is paused and indicates whether this frame
            can be restarted or not. Note that a `true` value here does not
            guarantee that Debugger#restartFrame with this CallFrameId will be
            successful, but it is very likely.
