----------------------------------------
Summary: Add call expression with a class of UDF
Key: FLINK-17523
URL: https://issues.apache.org/jira/browse/FLINK-17523
Project: Flink
Issue Type: Sub-task
Components: Table SQL / API
Reporter: Dawid Wysakowicz
Assignee: Dawid Wysakowicz
Fix For: 1.11.0
We should introduce a method that takes a class of UDF instead of an instance
similar to:
{code}
TableEnvironment#createTemporarySystemFunction(String name, Class<? extends
UserDefinedFunction> functionClass);
{code}
The API should look like:
{code}
public static ApiExpression Expressions:call(Class<? extends
UserDefinedFunction> function, Object... arguments)
{code}
