HBASE-24650 introduced CheckAndMutateResult class and changed the return type of checkAndMutate methods to this class in order to support CheckAndMutate with Increment/Append. CheckAndMutateResult class has two fields, one is *success* that indicates whether the operation is successful or not, and the other one is *result* that's the result of the operation and is used for CheckAndMutate with Increment/Append.
The new APIs for the Table interface:
```
/**
* checkAndMutate that atomically checks if a row matches the specified condition. If it does,
* it performs the specified action.
*
* @param checkAndMutate The CheckAndMutate object.
* @return A CheckAndMutateResult object that represents the result for the CheckAndMutate.
* @throws IOException if a remote or network exception occurs.
*/
default CheckAndMutateResult checkAndMutate(CheckAndMutate checkAndMutate) throws IOException {
return checkAndMutate(Collections.singletonList(checkAndMutate)).get(0);
}
/**
* Batch version of checkAndMutate. The specified CheckAndMutates are batched only in the sense
* that they are sent to a RS in one RPC, but each CheckAndMutate operation is still executed
* atomically (and thus, each may fail independently of others).
*
* @param checkAndMutates The list of CheckAndMutate.
* @return A list of CheckAndMutateResult objects that represents the result for each
* CheckAndMutate.
* @throws IOException if a remote or network exception occurs.

throw new NotImplementedException("Add an implementation!");
