Class ExecutorAsyncOperations

java.lang.Object

io.micronaut.data.runtime.operations.ExecutorAsyncOperations

All Implemented Interfaces:

AsyncRepositoryOperations

public class ExecutorAsyncOperations
extends Object
implements AsyncRepositoryOperations

An implementation of AsyncRepositoryOperations that delegates to a blocking operations and specified Executor. This can be used in absence of true asynchronous support at the driver level.

If a backing implementation provides a async API then the backing implementation should not use this class and instead directly implement the AsyncRepositoryOperations interface.

Since:

1.0.0
