## Methods

| Name | Description |
| --- | --- |
| [Get<T\>\(\)](https://docs.sisk-framework.org/api/Sisk.Core.Entity.TypedValueDictionary.Get.md#Sisk_Core_Entity_TypedValueDictionary_Get__1) | Gets a singleton previously defined in this context bag via it's type `T`. |
| [GetOrAdd<T\>\(Func<T\>\)](https://docs.sisk-framework.org/api/Sisk.Core.Entity.TypedValueDictionary.GetOrAdd.md#Sisk_Core_Entity_TypedValueDictionary_GetOrAdd__1_System_Func___0__) | Gets a singleton previously defined in this context bag via its type `T`. If it does not exist, it adds the object to the context bag using the provided `getter` function. |
| [GetOrAdd<T\>\(\)](https://docs.sisk-framework.org/api/Sisk.Core.Entity.TypedValueDictionary.GetOrAdd.md#Sisk_Core_Entity_TypedValueDictionary_GetOrAdd__1) | Gets a singleton previously defined in this context bag via its type `T`. If it does not exist, it adds the object to the context bag by creating a new instance of `T`. |
| [GetOrAddAsync<T\>\(Func<Task<T\>\>\)](https://docs.sisk-framework.org/api/Sisk.Core.Entity.TypedValueDictionary.GetOrAddAsync.md#Sisk_Core_Entity_TypedValueDictionary_GetOrAddAsync__1_System_Func_System_Threading_Tasks_Task___0___) | Asynchronously gets a singleton previously defined in this context bag via its type `T`. If it does not exist, it adds the object to the context bag using the provided asynchronous `getter` function. |
