Property Modifiers Type Description
[bindingStack](./context.resolutionsession.bindingstack.md) `readonly` Readonly<[Binding](./context.binding.md)>\[\] Getter for bindings on the stack
[currentBinding](./context.resolutionsession.currentbinding.md) `readonly` Readonly<[Binding](./context.binding.md)> \| undefined Getter for the current binding
[currentInjection](./context.resolutionsession.currentinjection.md) `readonly` Readonly<[Injection](./context.injection.md)> \| undefined Getter for the current injection
[injectionStack](./context.resolutionsession.injectionstack.md) `readonly` Readonly<[Injection](./context.injection.md)>\[\] Getter for injections on the stack
[stack](./context.resolutionsession.stack.md) `readonly` [ResolutionElement](./context.resolutionelement.md)\[\] A stack of bindings for the current resolution session. It's used to track the path of dependency resolution and detect circular dependencies.
## Methods
Method Modifiers Description
[describeInjection(injection)](./context.resolutionsession.describeinjection.md) `static` Describe the injection for debugging purpose
[fork(session)](./context.resolutionsession.fork.md) `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()](./context.resolutionsession.getbindingpath.md) Get the binding path as `bindingA --> bindingB --> bindingC`.
[getInjectionPath()](./context.resolutionsession.getinjectionpath.md) Get the injection path as `injectionA --> injectionB --> injectionC`.
[getResolutionPath()](./context.resolutionsession.getresolutionpath.md) Get the resolution path including bindings and injections, for example: `bindingA --> @ClassA[0] --> bindingB --> @ClassB.prototype.prop1 --> bindingC`.
[popBinding()](./context.resolutionsession.popbinding.md) Exit the resolution of a binding
[popInjection()](./context.resolutionsession.popinjection.md) Pop the last injection
[pushBinding(binding)](./context.resolutionsession.pushbinding.md) Enter the resolution of the given binding. If
[pushInjection(injection)](./context.resolutionsession.pushinjection.md) Push the injection onto the session
[runWithBinding(action, binding, session)](./context.resolutionsession.runwithbinding.md) `static` Run the given action with the given binding and session
[runWithInjection(action, injection, session)](./context.resolutionsession.runwithinjection.md) `static` Run the given action with the given injection and session
[toString()](./context.resolutionsession.tostring.md)
