Description copied from interface: ReturnValue

Calling this method on a ReturnValue object, provided as an argument in a method from MapMethods, designates that the ChronicleMap's method (backed by this MapMethods's method) should return the given value.

It is not allowed to call returnValue() twice during a single MapMethods's method call.

Not calling returnValue() during MapMethods's method call will make the backed ChronicleMap's method to return null.

Parameters:

value - a Data object wrapping a value, which should be returned from a ChronicleMap's method, backed by the MapMethods's method, to which this ReturnValue instance was passed as an argument
