allowEagerInit - used as a composite key.

value - value to store against the key, can be null.

Returns:

*previous* value held in the map for the given key.

                               boolean allowEagerInit)

Get the value stored against the key made of the parameters passed. Note it will return null if the value has not been stored. However if the key has been used in a put call it will return a BeanNameCacheResult that contains a null value.

Parameters:

type - used as a composite key.

includeNonSingletons - used as a composite key.

allowEagerInit - used as a composite key.
