Xiaogang Shi commented on FLINK-5023: ------------------------------------- The only old method affected is the `value()` method in ValueState. All other states have already implemented the `get()` method. We can implement `ValueState#value()` by wrapping the `get()` method to avoid any changes to existing code. The introduction of ReadableState<T> works. But I think the additional interfaces will make the code "verbose" :) > Add get() method in State interface > ----------------------------------- > > Key: FLINK-5023 > URL: https://issues.apache.org/jira/browse/FLINK-5023 > Project: Flink > Issue Type: Improvement > Components: State Backends, Checkpointing > Reporter: Xiaogang Shi > > Currently, the only method provided by the State interface is `clear()`. I > think we should provide another method called `get()` to return the > structured value (e.g., value, list, or map) under the current key. > In fact, the functionality of `get()` has already been implemented in all > types of states: e.g., `value()` in ValueState and `get()` in ListState. The > modification to the interface can better abstract these states. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
