--------------------------------
Summary: Unify FunctionInterfacesWithException implementations
Key: FLINK-12826
URL: https://issues.apache.org/jira/browse/FLINK-12826
Project: Flink
Issue Type: Improvement
Affects Versions: 1.9.0
Reporter: TisonKun
Assignee: TisonKun
Fix For: 1.9.0
An elegant FunctionInterfacesWithException is like {{BiConsumerWithException}},
which contains
1. Functional method, e.g., {{#accept}}
2. Unchecked adapter static method.
Current {{org.apache.flink.util.function}} use 3 strategies to implement point
2.
1). As above
2). Use another class, e.g., {{CheckedSupplier}}. This is quite tricky because
we have both {{ThrowingSupplier}} and {{CheckedSupplier}} and the latter is no
more than a static factory wrapper...
3). {{FunctionUtils#uncheckedXXX}} Yet another approach.
I propose to unify these 3 ways into the first way, especially giving
{{ThrowingSupplier}} and some others are marked as {{Public}}.
