JdbcFunction.SurroundOperator (JDUT:parent 1.0.0-SNAPSHOT API)

Type Parameters:

T - The type of fed object

R - The type of returned object

All Known Implementing Classes:

Transactional

Enclosing interface:

JdbcFunction<T,R>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public static interface JdbcFunction.SurroundOperator<T,R>
```
This operator is used to surround fed JdbcFunction by the implementation of surrounding.
For example:
```
 static <T, R> JdbcFunction.SurroundOperator<T, R> buildLogging(Logger logger)
 {
     return surroundedFunc -> v -> {
         logger.info("Before Invoke: {}", v);

         R result = surroundedFunc.apply(v);

         logger.info("After Invoke: {}", v);

         return result;
     };
 }

 JdbcFunction<Integer, Integer> loggedFunc = sourceFunc.surroundedBy(buildLogging(logger));
 
```
