| currentInjection | readonly |
Readonly<Injection> | undefined | Getter for the current injection |
| injectionStack | readonly |
Readonly<Injection>[] | Getter for injections on the stack |

Methods
| Method | Modifiers | Description |
|---|---|---|
| describeInjection(injection) | static |
Describe the injection for debugging purpose |
| fork(session) | static |
Fork the current session so that a new one with the same stack can be used in parallel or future resolutions, such as multiple method arguments, multiple properties, or a getter function |
| getBindingPath() | Get the binding path as bindingA --> bindingB --> bindingC. |
|
| getInjectionPath() | Get the injection path as injectionA --> injectionB --> injectionC. |
|
| getResolutionPath() | Get the resolution path including bindings and injections, for example: bindingA --> @ClassA[0] --> bindingB --> @ClassB.prototype.prop1 --> bindingC. |
|
| popBinding() | Exit the resolution of a binding | |
| popInjection() | Pop the last injection | |
| pushBinding(binding) | Enter the resolution of the given binding. If | |
| pushInjection(injection) | Push the injection onto the session | |
| runWithBinding(action, binding, session) | static |
Run the given action with the given binding and session |
| runWithInjection(action, injection, session) | static |
Run the given action with the given injection and session |
| toString() |
