@Deprecated(since="3.0", forRemoval=true) public abstract class ReactiveWrappers extends Object
Deprecated, for removal: This API element is subject to removal in a future version.
since 3.0, use ReactiveWrappers instead as the utility was moved into the org.springframework.data.util package.
Utility class to expose details about reactive wrapper types. This class exposes whether a reactive wrapper is supported in general and whether a particular type is suitable for no-value/single-value/multi-value usage.

Supported types are discovered by their availability on the class path. This class is typically used to determine multiplicity and whether a reactive wrapper type is acceptable for a specific operation.

2.0
