Method Detail

isSuccessful

boolean isSuccessful()

Some commands may want to provide information on whether the command was successful or not. This is different from a failure, which usually would result in an exception being thrown. An example is a putIfAbsent() not doing anything because the key in question was present. This would result in a isSuccessful() call returning false.

Returns:

true if the command completed successfully, false otherwise.
