    executionContext - The ExecutionContext to which this object is bound to.
    
    beanIdStore - The BeanIdStore to which this object is bound to.

public void clear()
```
    Description copied from interface: BeanContext
    
    Removes all the beans from the bean map
    
    Specified by:
    
    clear in interface BeanContext
  - getBeanMap
```
public Map<String,Object> getBeanMap()
```
    Description copied from interface: BeanContext
    This returns a map which is backed by this repository. Changes made in the map are reflected back into the repository. There are some important side notes:
    - The write performance of the map isn't as good as the write performance of the BeanRepository because it needs to find or register the BeanId every time. The read performance are as good as any normal Map.
    - The entrySet() method returns an UnmodifiableSet
    - When a bean gets removed from the BeanRepository then only the value of the map entry is set to null. This means that null values should be regarded as deleted beans. That is also why the size() of the bean map isn't accurate. It also counts the null value entries.
    Only use the Map if you absolutely needed it else you should use the BeanRepository.
    Specified by:
    
    getBeanMap in interface BeanContext
  - setBeanInContext
```
public void setBeanInContext(BeanId beanId,
                             boolean inContext)

    Description copied from interface: BeanContext
    
    Mark the bean as being in context.
    This is "set" when we enter the fragment around which the bean is created and unset when we exit.
    
    Specified by:
    
    setBeanInContext in interface BeanContext
    
    Parameters:
    
    beanId - The bean ID.
    
    inContext - True if the bean is in context, otherwise false.
  - toString
```
public String toString()
```
    Specified by:
    
    toString in interface BeanContext
    
    Overrides:

    executionContext - The Associated ExecutionContext.
