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 interface OptionalIntBinaryOperator
```
Variation of IntBinaryOperator that returns OptionalInt instead of the raw value. OptionalIntBinaryOperator is typically obtained from ExceptionHandler.fromIntBinaryOperator(IntBinaryOperator), in which case its return value is empty when the underlying IntBinaryOperator throws an exception. See noexception tutorial.

ExceptionHandler.fromIntBinaryOperator(IntBinaryOperator), IntBinaryOperator

OptionalInt apply(int left,
                  int right)
```
    Variation of IntBinaryOperator.applyAsInt(int, int) that returns OptionalInt. If this OptionalIntBinaryOperator is obtained from ExceptionHandler.fromIntBinaryOperator(IntBinaryOperator), the OptionalInt will be empty only if the underlying IntBinaryOperator throws. Otherwise the returned OptionalInt just wraps the return value of underlying IntBinaryOperator.
    
    Parameters:
    
    left - see IntBinaryOperator.applyAsInt(int, int)
    
    right - see IntBinaryOperator.applyAsInt(int, int)
    
    Returns:
    
    OptionalInt typically wrapping return value of IntBinaryOperator.applyAsInt(int, int), or an empty OptionalInt (typically signifying an exception)
    
    See Also:
    
    ExceptionHandler.fromIntBinaryOperator(IntBinaryOperator), IntBinaryOperator.applyAsInt(int, int)
  - orElse
```
default IntBinaryOperator orElse(int result)
```
    Converts this OptionalIntBinaryOperator to plain IntBinaryOperator using default value. The returned IntBinaryOperator will unwrap present value from the OptionalInt if possible, or return result if the OptionalInt is empty.
    
    Parameters:
    
    result - default value to return instead of an empty OptionalInt
    
    Returns:
    
    plain IntBinaryOperator that either unwraps OptionalInt or returns default value
    
    See Also:
    
    orElseGet(IntSupplier), OptionalInt.orElse(int)
  - orElseGet
```
default IntBinaryOperator orElseGet(IntSupplier source)
```
    Converts this OptionalIntBinaryOperator to plain IntBinaryOperator using fallback IntSupplier. The returned IntBinaryOperator will unwrap present value from the OptionalInt if possible, or fall back to calling source if the OptionalInt is empty.
    
    Parameters:
    
    source - IntSupplier to query for fallback value when OptionalInt is empty
    
    Returns:
    
    plain IntBinaryOperator that either unwraps OptionalInt or falls back to source
