Dawid Wysakowicz updated FLINK-17523:
-------------------------------------
Description:
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}
*Important:* Update the javadocs in {{*Table}} as well.
