implementation that will match with query
handlers which return a multiple instances of the expected response type. If matching succeeds, the

function will be called, which will cast the query handler it's response to a

MultipleInstancesResponseType(Class<R> expectedCollectionGenericType)
Instantiate a
MultipleInstancesResponseType with the given
expectedCollectionGenericType as the type to be matched against and which the convert function will use
as the generic for the List return value. |

Match the query handler its response
Type with this implementation its responseType
R . |

Will return true in the following scenarios:

For example a <E extends ExpectedType> E[]

Will ensure that if the given response
is of another collections format (e.g. an array, or a
Stream
) that it will be converted to a List.
Should only be called if ResponseType.matches(Type)
returns true. Will throw an
IllegalArgumentException
